Boeing 737 800 Specifications Fuel consumption. How fast is the plane flying

Popularity travel through the air puts new tasks in front of the developers of passenger liners. Today Boeing 737 800 Experts consider a fairly successful design - these vessels use Pegasus Flyer, UTair, Aeroflot, Nord Vinda and other well-known carriers. However, the passengers are inexperienced in flights do not know how to choose the right place on board this model during registration. This review will highlight such a kindty topic.

Borf for the first time passed tests in 1998. Creating a liner - a consequence of competition. The aircraft is designed as an analogue of another iconic model -. The vessel refers to the third generation group and has improved characteristics relative to the base model.

The passenger salon here suggests two options for configuration - an aircraft designed to one class seats, including up to 189 seating and a two-class analogue, designed to accommodate up to 160 people. Less frequently encounter liners in which there is a separate compartment with the VIP class places.

Salon width 3,54 meters allows passengers to travel with comfort, and the total liner length in 39, 41 m made it possible to increase the quantity seating. The increased area (125 m) and the scope of the wings (34.31 m) in combination with a powerful engine of the aircraft helps Lainera to make flights at a distance of 5,765 km at maximum speed 852 km / h.

However, these parameters say nothing to the passenger who wants to fly by such an aircraft. For readers, we present specific information that is a Boeing 737 800. Salon scheme, the best places and numbers of the series, from which it is better to refuse - all this you will see in our article. The video below shows general characteristics Salon and flight on these sides.

General Principles Seating Passengers

People who have repeatedly flying regular and charter routes know that the acquired air ticket does not contain information about the passenger occupied place. This information is specified by an employee of the airport. However, at this time, a person does not see how the location of the places in Boeing 737 800 looks like, so newcomers make a decision at random. Moreover, quite often, such situations are the cause of spoiled impressions of the trip.

Experts recommend to study such nuances at home, before leaving the airport, to be fulfillment by the time of choice. A slightly declared the principles of landing on liners will help the plan of the Boeing 737 800 aircraft, which is presented in the articles gallery. Armchairs in the standard liner salon are located in two rows, each of them contains 3 places.

Now a few words about the fundamental aspects of the choice. People who fear fly, it is advisable to choose extreme seats located near the passage. This technique will help to avoid accidental views in the porthole and use the help of stewards as quickly as possible. In addition, these chairs make it possible to move freely, without causing the inconvenience of neighbors.

Although there are some negative sides here - the passenger who took the seat at the passage, will have to skip the travelers when they have the need to leave the place. In addition, passing past the service staff is sometimes lacound with passengers sitting with the edge.

The chair located in the center of a number of experts consider not the most the best choice For single passengers. After all, his location implies a flight in close proximity to unauthorized people. Many have discomfort in such circumstances. And the armrests engaged in neighbors will only strengthen such sensations.

Places next to the window will allow you to enjoy the surrounding view of the whole flight, but leave the seat will be difficult. To go out into the salon, you have to raise both neighbors. So in general, the first principles of selection of aircraft places 800 look like. The liner cabin scheme allows you to demonstrate this moment, but there are other ways to determine the location of the chair optimally for the flight.

Choice among classroom liner salons

Let's start with the consideration of each row for the comfort of the flight. Airline "Russia" It offers passengers the aircraft of this particular category in several different modifications. We will look at the model of this airfield VQ-BCJ and find out what criteria to choose sitting by buying a ticket for such Boeing 737 800.

Salon scheme, the best places and chairs, from which it is appropriate to refuse, we will list below using the letters of the Latin alphabet given to the labeling.

Here, the first three places are near the toilet of pilots and partitions of the cabin, but there is enough free space in front of the seats to go out, without bringing anything inconvenience. Somewhat different situations with second row. 2F, 2e, 2D are located directly behind the partition. Therefore, passengers that suffer from the fear of a closed space are better to abandon such a choice - after all, the wall in front of the eyes during the flight will only aggravate this phobia.

Plus, there is a good choice of food - after all, food is spread, starting with a liner's nose. Yes, and inconvenience with a crowned back of a person sitting in front of a person here is excluded. Wanting to purchase tickets in 14 row, consider that here is usually cooled than in the rest of the cabin.

All seats 15 and 16 of the row have restrictions on the laying of seats, because emergency exits are located in the sixteenth and seventeenth rows. 17 V, 17 C, 17 D and 17 E - the so-called Spase Seats - the places are quite comfortable, because the seats are here on a decent distance from the previous series. But here it should be borne in mind that all the specified places tickets will be sold only to adult passengers who have no disability and restrictions on movement. After all, in an emergency, the duty to open a spare outlet lies in people who occupy them.

Perhaps very not bad seats in the liner - it is 18a and 18f chairs - Before them is enough free space to exit. As for the least attractive options, here specialists call the seats installed in 33 rows, followed by toilets. Here there are always limitations of the folding chairs folding function. In addition, due to the permanent visit to the toilet passengers, there is always noisy.

Model Overview with Business Class Zone

Consider another model belonging to the same airline. VQ-BIZ liner - the only copy in the Russian park "Russia".

Here, the first three rows are occupied by the place of business class - dual seats. Of course, these places are sufficiently comfortable, but 1a, 1B, 1C and 1D are located immediately behind the pilot cabin partition. Accordingly, there is not enough free space in front of the armchairs, and the view of the wall is unlikely to impress tourists. Although it is advisable to purchase tickets here to work on the road.

Let us turn to and see what is a Boeing 737 800 aircraft scheme, how many places are provided by designers in this liner and which seats will become the best choice of passenger. In this salon there is 154 chairs.

Fly in the fourth row will be comfortable due to the free space in front of the seats - only a partition separating places ahead increased comfort. At 12 and 13 rows are an emergency hatch. That is, people who acquire places in 11 and 12 row should think about the probable absence of the opportunity to throw back the back of the chair.

13 C, 13E, 13V and 13D - seats located near spare doors - not bad option. Moreover, good option It will be a choice of 14 rows with places A and F. After all, there is enough free space in front of them.

Accordingly, the place of the latter, 29 rows become not the most optimal option. It is always crowded here and noisy because of the proximity of the toilets. In addition, the backs of the seats can not be folded completely. Yes, and the stewards, offering food, will reach here only after bypassing the entire aircraft. As you can see, the criteria for choosing a lot, and most of the nuances depends on the personal preferences of the passenger.

In order not to spoil the mood at the very beginning of the holiday during the flight, inexperienced passengers it is advisable to take advantage of the advice of experienced people. We present general guidelines for seating in the liner cabin. A person previously not flying on board this model is appropriate in detail examine the layout of the aircraft salon and get acquainted with the main characteristics of the model. In addition, it will not hurt at registration to ask the airline's employees about the choice or ask them to be advised.

Take into account the personal perception of turbulence. Here, experts suggest choosing places closer to the nose of the aircraft - shaking is not felt as much as in the tail. It is advisable to avoid acquiring tickets to the ranks located in front of evacuation hatches or toilets. Remember, here it is usually impossible to travel half a walk due to restrictions on security reasons and design features.

Seats located next to the liner's utilized zones are unlikely to meet the expectations of the passenger that dreams of flight in silence. There are always noisy and many people. Take your own personal preferences and qualities. Traveling with a domestic pet on hand is advisable to plan closer to the passage of the cabin.

RESULTS

As you can see, the criteria for choosing are simple. Thoughtful and planned approach will be the key to pleasant impressions of flight, because the space-selected place sets the tone to any trip. And the ability to choose a comfortable option will be wrapped with a good mood.

For many decades, Boeing Corporation holds a brand of the largest in its industry. The main capacities involved in the production of military and civil engineering used in aviation and space are located in Seattle. Boeing 737 800 Aircraft Releases Boeing Commercial Airplanes Unit.

Overview

Civil Turbofolder Nursing Surface Surfaces 737 Boeing Corporation began to produce since 1967. The model under consideration refers to the numerous family of Next Generation, which should have become worthy of the AIRBUS A320 competition.

The first order of the Corporation to create Boeing 737 800 was received in 1994, and after 4 years of the airline "Tuifly" (called "Hapag-Lloyd Flug") received this model. After that, the increased release of the new modification of the aircraft of the NG family, and many leading air carriers of the world began to update their park thanks to these machines.

Not left aside and Russia. Her airlines are also serviced by these liners:

• enjoying the Boeing 737,800 Aeroflot - at the moment they are in the park of the company 25 pieces;
• at the airline "UTair" several modifications of the boobies, of which 737-800 - 9 pcs.;
• along with Eirbusami, the company "S7" uses both Boeing, among which there are 19 model of model 737-800;

• lookestovskaya airline Victory flies exclusively on the aircraft of the NEXT Generation family - they are in the park 12 pcs.

Additional Information. Passenger Boeing 737 800 Corporation has released about 2135 pcs over the years, plus several modifications - a business version with the BBJ2 prefix and military technique 737-800ERX. Models civil aviation This family still stands on the stream in mind their demand.

Specifications

In technical terms, the Boeing 737 800 liner turned out to be a good option that made the model popular among air carriers. This suggests the competitiveness of the 737 Next Generation aircraft - they are practically not inferior in their characteristics of Eirbusam.

The comparative parameters of 2-branded aircraft are shown in the table below.

The Boeing model is equipped with 2 CFMI CFM56-7B24 / 26 motors with maximum facilities in 11930 kgf, with fuel tanks with a capacity of 26020 liters. Motors placed under the wings make less noise and more economical, compared with previous models.

Boeing 737 800 differs from other aircraft of its family modified wing, the area of \u200b\u200bwhich has become 25% more. It helped to increase the wing scope of almost 5 m, which led to the ability to take an additionally on board by 30% more fuel reserve. Technical characteristics of the Boeing of this model make it possible to use it for transcontinental flights.

The externally, this model is no different from other representatives of the family 737. One for all modifications of the nasal section and the cross section of the fuselage. But there is a supplement: under the front left door, a trapp on an electric drive, which is used in their work by aircraft. Although in some cases some airlines use it and for disembarking passengers.

Scheme of seating in the cabin of the aircraft

Initially, the interior of the Boeing 737 800 salon was created under the economic class, which makes it possible to increase the number of seats and save on operating costs. This option is just enjoyed by the budget domestic airline "Victory".

Large international airlines Conclude an agreement with the manufacturer on the supply of aircraft with a breakdown of the cabin on grade 2 - economic and business. On the liners of Russian carriers of the Boeing 737 800 aircraft scheme may differ slightly among themselves.

Here, an example will be considered a salon of one of the cars of the company S7, where 12 chairs are reserved for priority places, located in 3 rows pairwise on both sides of the passage.

In the economic class there is a triple layout of the chairs. Only a middle series of emergency exits, in the 13th row location of pairs. Catering and toilets compartments are located at the beginning of the cabin (in front of the business class) and in the tail part (for the last rows). The Boeing 737 800 aircraft salon scheme of the company "S7" is shown in Fig. above.

Description of places on blocks of rows

In any of the salons, the same place in the Boeing 737 plane is more comfortable, others are endowed with inconvenience. When it is possible to choose yourself appropriate place In the liner, not only the passenger with experience or a thorough challenge plan in the cabin will be able to make a mistake.

Business class

Even in the priority compartment of the liner there are its own characteristics that define good and not very zones. To guess with the best place in the aircraft Boeing 737 800 airline "S.7, it is worth considering each of the 3rd row:

• The 1st row can boast the free space and the absence of chairs folded in front. But the entire flight passengers will have to see a partition separating a business salon from the kitchen and a dressing room;
• The inconvenience of the 2nd row consist only in the folding chairs in front of the sitting passengers;
• For the 3rd nearby the partition is placed, which separates from the economy class. It is thin enough, so the noise coming from the rear salon will be well heard.

But all these nuances can close the eyes, taking into account the increased comfort, comfortable chairs and high service.

Economy class

In the Salon of the Economic Class of the Boeing 737 aircraft, most seats can be called standard. Several chairs are considered uncomfortable, but there is a very good seat location:

1. The 1st row of the economic salon (or the 4th numbering) is located immediately behind the partition, which will prevent enough comfortably accommodation in the chair. The entire flight will have to consider the dividing screen. There are fasteners for children's crackers, so it is better to sit with young children in this row, but such a neighborhood may seem too noisy to other passengers; of the advantages, 2 nuances can be distinguished:

• there are no folding chairs ahead;
• service begins with the beginning of the cabin, so there is a priority choice of dishes.

1. In the 9th row, extreme places in the sides can be called bad; If you like to look in the window, there are no portholes here;
2. To a row 12, you can make some comments - it is located in front of average outputs. Therefore, the backs of the chairs here either have a small angle of inclination, or do not recline at all;
3. The 13th row like it, other passengers from him are not delighted:

• the location of the chairs is uncomfortable - the row is between 2 episodes of outputs, so the backs on these seats do not recline;
• but there is an additional space that allows you to straighten your legs;
• these places attract those who travel a pair;
• on this series you can not travel with children, transport animals, and people with disabilities are not allowed;
• there is no place to post a manual sting.

1. Row 14 give preference - here are the best places in the plane. There is enough space ahead to comfortably accommodate in the chair. But the side seats (in sides) slightly bevelled, and on them from the emergency exit there is no armrest;
2. In the 27th row inconvenient turns out to be a place of place due to the proximity of the toilet. Not only the frequent walking of passengers on the salon can be interfered, but also created by them in the bathroom;
3. The most uncomfortable next is the last - 28th. The backs of the chairs do not lean away, resting in the partition, behind which the toilet is located. Passengers interfere with the flue of doors, the movement of passengers and the noise of the drain tank.

Taking into account the features of some seats in the economic and business cabin, it will be easier to select a place in the Boeing 737 800 plane for a comfortable flight (especially if you have a trip with children).

People having problems with the vestibular apparatus, it is better to choose chairs in a liner's nose - here less turbulence. People traveling alone can feel uncomfortable on central places.

Note! Those who are afraid of aircraft or suffers from claustrophobia, it is worth choosing the seats at the passages in the zones located closer to the outputs. Especially undesirable for them armchairs in sides, where there are no portholes.

Facilities

In the Boeing 737,800 aircraft salons, the chairs are equipped with sockets to recharging electronic devices. As for the Internet, domestic air transporters consider the Wi-Fi connection projects in the aircraft that they exploit.

In the salons of some liners operated by Aeroflot, monitors mounted on the rear panels. It is possible to connect your gadgets to mobile application Companies. The Panasonic EXW entertainment system is filled with a large video, - and a phonometh, which will not let me be bored during the flight.

In the aircraft of the company "S7" in armrests, in addition to recharging, a system for listening to music is mounted. Other entertainment is not provided. In the Boeing of the model under consideration, which are used by Russian carriers "UTair" and "Victory", no electronic systemproviding passengers a fascinating journey, not available.

In general, the 737th model of the Boeing of the 800th modification is quite convenient, comfortable transport for traveling abroad with good aerodynamic properties. Airplanes of the NEXT Generation Family of the State Boeing Corporation make a worthy contribution to the development of world aviation.

Location of the best places in the cabin

Passenger Salon airplane Boeing. 737 is able to accommodate from 100 to 215 passengers (depends on the layout option of the aircraft and its modification). The most common option is the presence of two classes (business and economy), so it is worth considering it in more detail. In this case, this is the Boeing 737-800 salon.

As shown in the scheme, the business class salon is equipped with 4 rows of places. There is a fairly wide central passage, and the seats are located according to the "2-2" scheme. Thanks to this, a considerable width of chairs in the business class is provided. In general, the business class shows very soft and comfortable seats, the distance between which is enough to throw back the back to the sufficient angle and turn the seat in comfortable beds. Places are enough and in order not to worry about the foot space, even people with high growth. The menu for passengers of this class is elegantly and features a wide selection of beverages and dishes.

The best for business class are places marked with literals a and g in the ranks with numbers 2 and 3. Their convenience is explained by the fact that they are located in the middle of the salon (and not in front or behind) and at the portholes, and therefore passengers sitting here Guaranteed a beautiful view from the height.

However, it should be remembered that certain disadvantages should be characterized for some business points. First of all, we are talking about places in a number under the number 1. The main minus is that they are located near the toilet and utility rooms. Consequently, all the disadvantages associated with such a "neighborhood" will experience the passengers of the first row to the fullest. Also not the best for business class will be places located in the fourth row (according to the passenger interior scheme). The thing is that they are closely adjacent to the thin partition separating the business class from a more noisy economy class. This means that noise from the economy class is likely to be heard to passengers of the places of this series, which will certainly not contribute to a full-fledged rest in flight. In a word, when booking tickets, it is necessary to take into account these features and buy tickets on the ranks with numbers 1 and 4 only if there are simply no tickets to other rows.

Following the field of business class there is an economy class salon. Chairs here are placed on the sides somewhat narrower than in the business class, the central passage according to the 3-3 scheme. The economy-class places occupy the ranks (as shown in the diagram) with numbers from 10 to 33. Chairs here are also sufficiently soft and comfortable, and their backs are able to lean at an angle of up to 45 degrees (depending on the aircraft model). The distance between the chairs is approximately 80 cm.

The best in the economy class are places indicated by the literals B, C, D and E in a number of 18. Their convenience is explained very simply: the chairs are arranged directly near the emergency exits. Therefore, the armchairs located in front of 18, as a rule, have very limited corners of the rejection of the back (or do not deviate at all), and the distance to them is somewhat more. This is necessarily due to emergency situation Provide passengers unobstructed access from the aircraft. However, this does not concern the places of 18 rows marked with the literals A and F. The fact is that the places located at the portholes slightly "beveled" to the parties, which makes them somewhat inconvenient. Also quite good (but in with reservations) are places in the 17th row. They are also located near emergency exits, therefore, and places for legs here are more, not to mention the small angles of folding the backs in front of the arrangements. However, on the other hand, due to the fact that these places are located in front of another emergency exit, their backs are practically not crowded.

Special attention should be paid to both places located in a number of 10. Before them is a partition that shares business and economy classes. Thanks to this, there is more space for the legs, and no one can reject the chair, located ahead, thereby limiting your space. Another plus is that the distribution of food begins with these places, which provides a large assortment of passengers sitting here. Nevertheless, it is opposite these seats, special cradles for infants are installed, which can create a number of inconvenience - after all, not every person will be able to relax peacefully when children cry near or cry. In addition, for the seats of the tenth row, the folding tables for feeding are mounted in armrests, which can also be somewhat inconvenient.

Not the best choice will be the locations of a number under number 16 (according to the scheme). They are located before an emergency exit, and their backs have a limited casting angle. The least attractive option for the economy class of the Boeing 737 aircraft are places located in 33 row, especially designated C and D according to the scheme. These places are located directly from the toilets, which means that the queues from passengers will accumulate here. The sound of clapping doors and buses may seriously spoil the impressions of flight and liner. To avoid this, you need to carefully choose places when booking and take into account the features of the aircraft.

History Boeing 737.

In the early 1960s, McDonnell Douglas and British Aircraft Corporation and British Aircraft Corporation worked on the creation of the near hospital passenger aircraft With low capacity. Initially, the Boeing Corporation in this competitive struggle was almost no chance. In addition, creating a new passenger aircraftThe name of Boeing 737 started a few years later than his competitors. To accelerate the development of the liner, technologies used in the construction of Boeing 707 and Boeing 727 were used. Nevertheless, a number of tests of the building of the new aircraft showed the shortcomings in the design, and some of its parts (for example, the wing) made fundamentally new.

The first customer Boeing 737 became the German airline Lufthansa. It was thanks to her that the number of passenger seats of the liner increased from 60, which were originally planned, to 103.

In 1965, the end of the development of a passenger liner Boeing 737 was announced, and two years later, the first aircraft was transferred to the customer. Commercial operation of the model began in 1968.

During the production of this liner, lively disputes and discussions were not died regarding the number of crew members for such an aircraft. Thus, trade union organizations achieved recognition of the fact that the plane of a similar class should have a crew exclusively of 3 people (three pilots or two pilots and a flight engineer). This decision, of course, was very unprofitable airlines due to the need to keep the larger state of pilots and increase costs.

After the meeting of the leaders of Alpa (Air Line Pilots Association - Association of Airline pilots), an appropriate resolution was adopted. She envisaged Boeing 737 crew from 3 people. At the same time, the Federal Civil Aviation Department of the United States allowed Boeing Corporation to pre-hasen 2 pilots in the crew for its aircraft. Nevertheless, the disputes lasted for a long time and to a certain extent "scared" from the Boeing 737 a number of potential customers, while playing, thereby, on the hand of competitors.

In the 70s of the 20th century, the popularity of the new Boeing 737 liner (then he had two modifications: 737-100 and 737-200) grew rapidly, and soon the number of orders for the aircraft exceeded thousands, especially on the model 737-200, having Extraked case and increased passenger capacity.

In the 1980s, the liner was seriously changed. The most significant of them was the installation of new turbofer engines, as well as a change in the shape of the gondola for them with a circular to a slightly "fuel". This is due to a small clearance of Boeing 737, due to which during takeoff or landing there was a threat of damage to engines. The liner cabin was equipped with the latest onboard electronics systems. In 1984, a new modification was developed and allowed - Boeing 737-300.

However, after the 70s and 80s of the 20th century, when Boeing 737 unconditionally possessed domination in the sector of narrow-body nearmight aircraft, the position of the liner was seriously undermined by the A320 passenger aircraft by Airbus. In this regard, Boeing was decided to establish a new family of 737, called NG (New Generation - a new generation). This line of aircraft entered such modifications as: Boeing 737-600, 737-700 and 737-800. Later, the model Boeing 737-900, developed in 2001, joined these models. The main feature of the passenger liners of the "New Generation" was an advanced system of on-board electronics, a new wing design, a more cozy crew cabin and a passenger interior, as well as a reduced mass and, as a result, the best flight specifications.

As of 2014, the Boeing Corporation carried out more than 8000 supplies of the 737 family of a family of 737, and the total number of orders for the liner exceeded 12,000. Thus, the Boeing 737 can safely be called the most mass passenger aircraft in history. It is also worth noting that the mass production of the 737th continues to this day.

Modifications of the aircraft

Boeing 737 aircraft are divided into 4 families, which, in turn, are represented by various modifications.

The Original family is presented by modifications 737-100 and 737-200.

• Boeing 737-100 - the first modification of the aircraft with the number of passenger places to 103. was produced mainly in 1965-1969.
• Boeing 737-200 - extended by 2 meters (compared to Boeing 737-100) modification, which has increased passed passenger and flight range. Manufactured from 1967 to 1988.

The Classic family is represented by 237-300, 737-400 and 737-500 modifications.

• Boeing 737-300 - a version of the aircraft with an increased (compared to the Boeing 737-200) of the fuselage length and passengerism. Commercially exploited since 1984.
• Boeing 737-400 - Modification with an even more elongated case, which caused a serious processing of air conditioning system in the cabin. Boeing 747-400 is characterized by an increased capacity.
• Boeing 737-500 is a model that is essentially a shortened version of 737-300. Flight range increased to 5,200 km.

The NEXT Generation family is represented by modifications 737-600, 737-700, 737-800 and 737-900.

• Boeing 737-600 - the first modification of the family. In fact, the replacement of the model Boeing 737-500, as characteristic has the same as accuracy. However, in the future, due to non-economic, the aircraft was notopullen.
• Boeing 737-700 - Modification with an increased amount of passenger places (compared to 737-600) and an increased range of flights. There is also a Boeing 737-700ER model (Extended Range - enlarged range).
• Boeing 737-800 - Liner, assumed as a replacement for Boeing 737-300. It has increased capacity (up to 190 passengers) and an elongated fuselage.
• Boeing 737-900 - Modification of the aircraft with the longest body in the family (42 meters). Number of passenger seats - until 190.

Also, based on the Boeing 737-900, 737-900ER was created with an increased passenger complex (up to 215 people) and an enlarged range of flights.

The 737 MAX family is currently being developed, it is assumed that it will be presented by models 737 MAX 7, 737 MAX 8 and 737 MAX 9.

Bóeing 737. - The most popular in the world narrowly fuselative jet passenger aircraft. Boeing 737. It is the most masses produced by the reactive passenger aircraft in the entire history of passenger aircraft building (6160 cars ordered and 5109 delivered). The aircraft is made by Boeing Corporation since 1967. Boeing 737. It is exploited so wide that at any time in the air is on average 1200 aircraft 737 , and every 5 seconds somewhere in the world, one "737th" in fact takes Boeing 737. - this is common name More than ten types of aircraft.

History

Boeing 737. It was designed for the passenger aircraft market of relatively low capacity and low range, where BAC 1-11 and DC-9 played the main role. In this struggle, initially Boeing was far behind its competitors: in 1964, when the development of the aircraft was launched, its competitors have already passed a flight certification. To speed up the development process, Boeing borrowed technologies used on Boeing 707 and Boeing 727 (most noticeable similarity of the fuselage Boeing 737. With the fuselages of these aircraft), however, on static tests with a 95 percent load, one of the wing devices was damaged by rearing the lack of this design. After reloading, a new, more perfect wing appeared, which allowed to use the aircraft on short runways and an increase in the cruising height of the flight. As a result, fuel efficiency increased. In general, the development of the aircraft cost relatively inexpensively and was carried out very quickly. Chairs in the cabin were located 6 in a row, which ensured a large capacity than their competitors who had five chairs in each row.

Modifications -100 and -200 recognizable thanks to the cigar-like engine gondola, almost fully built into the wing from its front to the rear edge. In the first models Boeing 737. PRATT AND WHITNEY JT8D engines with a low degree of double-circuit. Also, these models are easy to learn about the smooth bending of the upper edge of the keel.

Boeing 737-100 I made my first flight on April 9, 1967 and was commissioned by West German Lufthansa in February 1968. 737-200 For the first time, took off on August 8, 1967. Only 30 aircraft modifications were delivered. 737-100 . Boeing 737-200 With the elongated fuselage, it became much more popular and was produced until 1988. The first customer of this modification was the American airline United Airlines. After the release of 135 aircraft Boeing developed a fundamentally new, more efficient reverse mechanism, but such an improvement cost Boeing $ 24 million.

In the early 80s Boeing 737. Submitted first serious reconstruction. The largest change was the use of CFM International CFM56 engines instead of JT8D. CFM56 is a turbojet engine with a high degree of double-circuit. It is much longer in diameter, so it was suspended under the wing on the pylons, and the principle of the built-in engine was refused. But the small clearance of the aircraft (the feature borrowed from the Boeing 707) in this case created the problem, so the aggregates were solved, located usually at the bottom of the engine sections, place on the sides of the compressor section. Unusual "flattening" gondola is connected with this. At the same time, cab 737 It was improved to Boeing 757 and Boeing 767. The first model of the aircraft of the new series Classic. - 737-300 It was commissioned in 1984. In the future, this generation has been replenished with airplanes. 737-400 and 737-500 .

To the 90th Boeing 737. Lighted technological superiority in favor of A320. In 1993, a 737-X program was launched or NG. (Next Generalation - New generation).

Series 737NG. includes a series 737-600 , -700 , -800 and -900 noticeably different from the first aircraft of the family 737 . 737NG. - This is a completely new series, having little in common, except for the design of the fuselage, with original aircraft Boeing 737.. The largest changes have become new wings, new avionics, improved engines. The total number of parts of the aircraft decreased by a third, which reduced its mass and improved controllability. Additional transformations also include optional vertical finishes of wings - "Winglets" ("Winglets"), which significantly reduce fuel consumption and improving the take-off characteristics. The possibility of installing "Winglets" and on airplanes, originally not equipped with them, including early types.

In 2001, the aircraft was created by lengthening the fuselage Boeing 737-900which actually accommodates passengers more than Boeing 707 and performs in one class with Boeing 757. In one week orders for -900 Received more than all family 757 For the entire 2004 year. In 2005 Boeing 737. Lost one of its main distinguishing features - additional "abnormal" windows, located on top of the main windows, in the cockpit of pilots. In the 60s, such glasses were the requirement of the Federal Aviation Administration of the United States with a relevant certification for improving the review at large roll corners. However, today it is not required, and Boeing offers the customers of the aircraft this option to choose from.

In July 2005, Boeing announced the start of work on creating an option 737-900ER (Extended Range - enlarged range) previously known under the designation 737-900x. 737-900ER sizes the same with 737-900 But it installed an additional pair of doors. Passenger capacity is increased to 215, 26 more than that 737-900 . The first aircraft is planned to be put in the first half of 2007. The first operator is Lion AIR with the order of 30 aircraft.

Also announced works on the aircraft 737-700ER. In size it is again similar to its prototype, but additional ones are installed on it. fuel tanks And the maximum take-off weight was increased. The first customer is the Japanese All Nippon Airways.

Boeing has already hinted that the next big project after Boeing 787 will be the aircraft for replacing the family 737 Although it is not entirely clear whether a new design will be developed over the next 7-10 years. However, such a plane today is indicated as 737RS.

The first flight was carried out on February 24, 1984. The first serial cars were delivered to customers in the autumn of the same year.

737-400

Boeing. 737-400 It was lented by 3 meters up to 35.23 meters, compared with 737-300, primarily according to the requirements of charter carriers. In connection with the increase in the volume of the cabin, it was necessary to recycle the air conditioning system, which was the main difference of this aircraft in the family. With these changes related to the presence of two missed windows on each side, thanks to which aircraft -400 easily distinguish from other 737 Classic. Also the aircraft is equipped with additional emergency outputs on the wing (two on each side, whereas on -300 and -500 - one by one) and the tail fifth, which prevents the destruction of the structure of the tail part of the fuselage in the case of a circuit of the runway during takeoff. These features of the design of steel are characteristic and for subsequent "long" 737 (-800 , -900 ).

737-900 / -900ER

For more successful competition with airbuses, a model was developed Boeing 737-900 - The longest plane of the family. But the number of doors was not increased, as required by the Federal Aviation Administration. Therefore, the passenger capacity of the aircraft was significantly reduced not so much due to the flawlessness of the structure, as because of the laws. After the completion of the production of the 757th, a new aircraft was presented - Boeing 737-900EREquipped with additional tanks and doors. The advanced design of the wing provides a small fuel consumption at cruising speed of 0.78 mAh. The first customers are Alaska Airlines (737-900) and Lion Air (737-900ER). Based on the aircraft developed option BBJ3..

Main Competitor - A321, although Boeing 737-900 Noticeably less.

On seven planes 737 ClassicThe tank capacity is increased to 16,200 kg, it is also possible to install an additional fuel tank in the rear trunk.

In general, similar 737 NG.The tank capacity is increased to 20800 kg, fuel tanks changed: the central tank occupies not only the centerlane, but also part of the root from the root to the engine pylon. Also changed the location of the pumps and the water removal system from the tanks has been added.

Other facts

• The Boeing 737 is largely owned by the Southwest Airlines airline, which does not use any other aircraft in its fleet, except for the 737th.
• The first aircraft of the 737 family was nusted "Baby Boeing" ( english - Baby Boeing.), Since from the point of view of many pilots was similar to little Boeing 707.
• In United Airlines, the plane received another nickname - "Guppy", probably in honor of the eponymous fish.
• The engines of Classic (-300, -400 and -500) aircraft engines) and Next Generation (-600, -700, -800, -900) air intakes have a non-circular form, unlike most other aircraft. Engineers needed to be located inside the engines of the supplementary equipment to increase their power. Initially, Boeing was designed for small Pratt & Whitney engines, but the next generation was required to install larger CFM65 engines. Due to the small clearance, the engine could only be expanded horizontally. As a result, the cross section of the engine gondola turned out to be triangular rather than round. In industry, such a decision was called a "hamster" ( english - Hamsterisation) Due to the similarity of the engine with hamster cheeks.
• At 737th, the same fuselage is used, which is 7,07m, 727th and 757th, only shortened.
• Most cockpit planes of the 737 aircraft are equipped with additional windows over the main windshield. T.N. "Absorption" windows are borrowed from Boeing 707. Their main task is to expand the angle of review, especially with rolls. With the improvement of the air avionics, the windows have become superfluous, and the pilots often cover them with a newspaper to protect against sunlight. Since 2004, the cockpit 737 does not imply the presence of these braids.
• In the fuselage of any Boeing 737, you can put the GE90 aircraft motor, which equipped with Boeing 777. This is one of the largest engines installed on airplanes.
• The total number of Boeing 737 details is 3000551 (three million five hundred fifty one) thing!
• In the 737th there are no shadows of the main chassis racks. The main chassis is removed in the deepening in the center of the aircraft, while there are practically no aerodynamic resistance. If you watch the 737th, standing on the ground, it is easy to notice the black rings of the tires under the wings. In Boeing, they argue that such a scheme is aimed at reducing the weight of the aircraft.
• Given the number of Boeing 737 exploited, it is estimated that one aircraft takes off every 5 seconds.
• On 737th there is no emergency drainage system of fuel. In the event of an accident, the pilot is forced to circle, producing fuel, or if there is no time to sit with overload.

The largest competitors in the civil aviation market are two concern: in Europe - aerobus, in the USA - Boeing. The first flagship plane is considered the model A-320. The second answered an equally successful machine called Boeing 737-800.

Boeing has a whole family of seven hundred thirty-seventh aircraft, which has begun in 1967. After that, the model range is constantly upgraded. 737-800 - a common model that has become a continuation of a successful Boeing 737-400.

History of creation

The 737 family has become popular in civilian transport segment. Moreover, such positions company achieved throughout the civil aviation of the world. Statistics says that at each moment of time 1200 Boeing 737 aircraft flies in the sky. And every five seconds the liner of this model makes landing or take off.

The countdown of the family history began with the models of 737-100, and next - 737-200. But they were spent in terms of fuel consumption. The model number has influenced the change of the oil crisis.

Continued the Boeing 737-300 models, and then Boeing 737-400. The latter turned out to be successful and worked out dead for them. When it was time, on the basis of four hundredth Boeing created 737-800. A combination of economy, technological and good passenger capacity, he quickly won respect from leading carriers of the world.

To date, 737-800 is considered one of the most popular projects of the entire family.

The first delivery of liners was carried out in 1998. These aircraft fly so far and are used so wide that orders for them are painted for years ahead.

The entire Boeing Family 737 today is presented by more than 10,000 models working throughout the planet. And the demand for their production does not pass. The model range with the design of -800 is considered modern and technically developed, and still did not share its resource.

In general, the 737 family is so big that it is even conventionally divided into generations:

• original (which includes the first models with the designation of Boeing-100 and Boeing-200);
• classic (predominantly models of Boeing-300, Boeing-400 and Boeing-500);
• next Generation (Boeing-600, Boeing-700, Boeing-800 and Boeing-900);
• Max (a new generation, which is intended to change the popular Boeing-800 and Boeing-900).

Boeing 737-900, which began to go on sale in 2001, differs from the predecessor (737-800) longer fuselage. After presentation, this model received so many pre-orders for one day, which bypassed the whole family ordered for the whole year.

In general, each model 737 families have one characteristic feature. In addition to changing technical and constructive nature, each new machine has been longer than the previous one.

Construction of fuselage, wings and cabins, engines

Boeing 737-800 differs little from the remaining aircraft series of generation Next Generation on the aerodynamic scheme. But with the generics (737-100 and 737-200) already a little common feature.

The fuselage of the aircraft extended more than 3 meters (in comparison with the prototype - four hundred and model), while considerably increased passenger capacity.

New models 737-800 were created to replace an outdated 737-400 (170 seats), but were able to receive a number of improvements.

Thus, the new plane has already made 189 people as much as possible and has undergone significant changes in the design.

The Boeing Plane 737-800 is a low-flailed pulp with a wing form. The new generation of aircraft was created in order to return the advantage in the fight with the main competitor - 0. Therefore, serious changes touched first of all the design of the wing, control systems and engines.

The wing received a new most important difference - special finishes (Winglets). This design gives a great advantage in terms of efficiency and significantly improves liner performance on take-off and when landing (along the length of running and braking, separation speed).

Large differences from previous versions also received a cabin, which not only has been changed design, but has greatly advanced by technical equipment. So, traditional analog devices completely replaced. First used ray screens, and later - liquid crystalline.

New developments made it possible to reduce the weight of the aircraft by almost a third, increased the range and speed, and also improved safety indicators in the air.

Under the wing, two engines are installed, which operate on a turbofer pull.

Power plants are two (one on each console). Production is engaged in CFM International. Series of used engines - CFM-56-7B.

Such engines began to set since 1980, due to their high at that time of efficiency and sufficient power. But the design features of new power attitudes imposed a print on the appearance of the liner. Due to the large diameter, both engines moved to pylons under the wing (refusing to embedded structures). Reduced and clearance of the aircraft.

With full loading, the distance from the engines to the Earth is 46 centimeters. This makes the Boeing data low on landing (lowlands) and imposes an imprint for high demands on host airports (in particular, to the state of the runway).

Such a low location of engines, including led to constructive changes. It was decided to transfer some mechanisms and details in terms of engines (while they were usually located below). This led to some substantial change in the fuselage. It has already become visually slightly flattened. This is considered a characteristic feature of the Boeing 737 of the new generation (Series -600, -700, -800 and -900).

Fuel system

The location of the fuel tanks in the 737-800 classic models. Two are located in the wing of the aircraft (in consoles on both sides). There is also a central tank, on the generation of Next Generation, occupying not only part of the fuselage, but also turns into the base of the wing and giving up to pylons on which the engines are suspended.

Fuel consumption is organized in such a way that it first rolls out a fuel from the central tank, and then from the wing.

The feature of the Boeing 737 is the inability to reset the fuel in case of emergency situations. For landing, you have to either risk and plant a machine with a maximum weight, or produce fuel in the air.

The BBJ model range aircraft provide for the installation of additional fuel tanks. They can be placed in luggage compartments (up to 9 tanks). This method increases capacity on board the fuel to 37 tons.

Chassis

The Boeing 737-800 chassis differs little from classic options, but have their own design features.

So, three racks are installed: one is taxiing and located in the nose, the other two (main) are fixed on the centerlane. Each rack has two wheels.

The characteristic feature of the Boeing of the Next Generation generation is large on the diameter of the engines. This trait influenced not only to change the fuselage, but also led to redevelopment of the chassis racks. They began to increase additionally and lengthen - to increase the clearance when landing.

Distinctive feature of the Boeing 737 - not closed with consoles rear racks chassis.

In folded form, they are part of the aerodynamic scheme. This measure increases resistance in flight (however, due to the work of the engineers is completely insignificant), but caused by a reduction in additional equipment on board and loss of weight. In particular, additional hydraulics are not installed for the rear racks.

Since 2008, NEXT Generation aircraft brakes have significantly changed. They began to put carbon brakes, which, with less weight and greater resources, work more efficiently.

Passenger Salon and Operators

Plane Boeing 737-800 is highly popular in the world. He deserved special love from budget carriers (Loocosostrov), which form whole parks of these models of American liners for themselves.

The 737-800 model is perfect for medium-sighted flights or short routes. Therefore, they are most often used in the framework of one continent and find them the replacement today is difficult (unless the A320 aerobus).

The biggest popularity of Boeing 737-800 enjoyed in the native market - in the USA. Most the largest air carriers From there:

• SOUTHWEST AIRLINES (696 aircraft);
• UNITED AIRLINES (325 aircraft);
• American Airlines (328 aircraft);
• Delta Air Lines (83 aircraft).

In Europe, Boeing 737-800 is also popular, although in many airlines works together with A320 airbuses. The most massive representative of the 800th models at the Irish budget carrier Ryanair (413 aircraft).

In Russia, the aircraft is widespread and used by Aeroflot, Russia, Victory, "Utair" and "S7 Airlines" by airlines.

The latter of the named companies is so ambitious that orders the name of the name aircraft according to an individual project at the factory, they are called Boeing 737 800 S7.

Boeing 737-800 is a narrow-body aircraft (in it one pass between the rows of seats). The layout of the salon in the economic class is found in the form "3-3", and in the business cabin - "2-2".

The maximum capacity of liners is 189 people. Such a number of passengers can be transported in an airplane fully equipped with economy class economy.
There are versions of the aircraft with a mixed layout of passenger seats: 12 places for business travelers and 150 - economical options. The total capacity is 162 people.

Outputs from the cabin are provided in front part, in the middle of the fuselage and in the tail part of the liner.

It is possible to plant passengers and access to both boards.

The technical characteristics of the Boeing 737-800 are presented in the table:

Length / width (with wing) / height	39.37 m / 34.32 m / 12.62 m
Fuselage / Salon Diemeter	3.76 m / 3.54 m (equally at the entire generation)
Ceiling in salon	2.20 M.
Cruising speed	852 km / h
Maximum range	5765 km
Maximum flight altitude	12.5 km
Empty aircraft mass / maximum take-off	41.4 t / 79 t
Fuel	26 000 L.
Mileage Length when take-off / landing	2241 m / 1630 m

Boeing 737-800 model range

Boeing 737 is used not only for civilian traffic. And not exclusively for regular flights. The BBJ2 modification is distinguished by an expensive layout of the cabin (business option, with sofas, finishing and low capacity).

The plant works tightly with military orders. For them, the company has created a model 737-800ERX and P-8 Poseidon.

Place of production

Initially, part of the work on the assembly of 737 families was carried out at the main factory of the company not far from Seattle. The fuselage and wing were placed there, and the tail part was going at the factory in Wichito. Some details (chassis, technical filling) were made joint forces or third-party organizations. The final assembly was carried out in Seattle, where the details of the liners were flushed.

Later the assembly was transferred to Wichito, where railway Small structural elements were transported, and even the fuselaces with wings.

The scheme with the delivery of details on the assembly conveyor, tested at the factory in Wichita began to be applied since 1970 and is used to our time.

Only today the assembly is moved south, to the city of Renton.

Perspectives

The main prospects for the development of the Middle Highways of Boeing Binds with the MAX generation. From January 2016, final tests and the first of the Boeing 737 model Max was sold in the spring of 2017. They can also carry a lot of passengers and are supplied with the latest security systems and avionics.

Already in the near future, they will gradually exhibit the 737-800 model from the market, and then 737-900.

Conclusion

Boeing 737-800 is a successful draft American company, which is characterized by a very thoughtful combination of high capacity, successful indicators for efficiency, flight range and safety.

Liner began to be used by most airlines in the world.

Pilots and passengers celebrate its convenience and security. Model 737-800 took into account the shortcomings of the past aircraft of the SU family and thanks to this became so popular. The number of cars released is so great that all records beats. This means that even with the arrival of new models, Boeing 737-800 will meet in heaven.
