Boeing 777 200 aircraft description. The plane that flies the farthest! Production and modifications

Boeing 777 according to various world ratings, the safest aircraft. Boeing 777 (Boeing 777) is a wide-body turbojet airliner for long-haul airlines. The aircraft has been developed since 1991. The first aircraft entered service on June 7, 1995. The Boeing 777 is powered by two General Electric GE90 turbofan engines. Boeing 777 aircraft can carry from 300 to 550 passengers.

The Boeing 777 aircraft was developed entirely on computers. During the development of the airliner, not a single paper drawing was made. All documentation was created using a 3D design program. In addition, the Boeing 777 set a flight distance record for aircraft with a takeoff weight of 250-300 tons on the route Seattle (USA) - Kuala Lumpur (Malaysia) with a length of 20,045 kilometers. The record was set on April 2, 1997. In 2013, the world flight distance record was exceeded and the Boeing 777 covered a distance of 21,501 kilometers. The Boeing 777 can fly almost without landing to any airport in the world. Boeing 777 has gained great popularity among all airlines and passengers. Since the 90s, several aircraft modifications have been developed. Aircraft of the Boeing 777 family have places for crew rest: two armchairs and two beds.

In total produced Boeing 777 aircraft (all models) for 2012 - 1372 units.

Economy class salon. The economy class cabin of the Boeing 777 can accommodate up to 555 passengers. The interior of the cabin is made in the style of Boeing Signature Interior. The salon has enlarged luggage racks and interior lighting is made according to the scheme of indirect lighting. In the economy version, the salon is equipped with ten seats in a row. Compared to previous models of Boeing aircraft, the 777 has larger windows. In 2011, Boeing decided to change the interior of the Boeing 777. The interior of the Boeing 787 was taken as the basis. This program is called the common cabin experience.

Salon business and VIP class. In the 1st class cabin (business class) there are 6 seats in a row. Business class cabins have more free space for passengers. Salon 1 class is equipped with more comfortable chairs. Some Boeing 777 aircraft are equipped with VIP class cabins. All conditions for a comfortable flight are created in the VIP lounges. Armchairs can be transformed into a full bed. Airline Boeing 777 Imperial Salon. Transaero has equipped several Boeing 777s with Imperial saloons. Salon Imperial was created for those who love luxury and comfort. Salon Imperial is the highest achievement of civil aviation service. The passenger of the Imperial cabin has individual attention and excellent service. The best employees of the company work on board the Imperial cabins. The armchairs of the Imperial saloon have gold upholstery and can be laid out 180 degrees, turning into a bed. The chairs are arranged so that there is a porthole next to each (possibly two portholes). The salons of the Boeing 777 Imperial have excellent cuisine: they serve dishes from sterlet, venison, with caviar and quail eggs. Passengers can also taste the desserts of French confectioners.

Boeing 777-200
The first modification of the Boeing. The first commercial flight took place on May 15, 1995. The Boeing 777-200 was developed for US domestic flights. The aircraft is designed for lines up to 8300 kilometers long. Boeing 777-200 is the base model. The Boeing 777-200 aircraft was designed specifically for US domestic transportation. The first Boeing 777-200 aircraft was purchased by United Airlines.

Boeing 777-200ER
Boeing 777-200 ER aircraft were purchased by the Russian airline Transaero. Boeing 777-200ER is designed for long-haul airlines. Boeing 777-200 ER aircraft are designed for transatlantic flights. The ER (Extended Range) index means an extended range aircraft. The Boeing 777-200ER set a record single-engine flight (ETOPS emergency flight) of two hours and 57 minutes. Boeing 777-200ER is the best selling aircraft in the world. In 2013, more than 500 aircraft of the 777 model are operated in the world.

Boeing 777-300
The Boeing 777-300 differs from the Boeing 777-200 in a longer fuselage (more by 11 meters) and more efficient engines (saving up to 40%). The Boeing 777-300 is designed to replace the Boeing 747. In terms of roominess and flight range, the 777 is not inferior to the 747, but exceeds it in terms of comfort and better flight qualities. The first flight of the Boeing 777-300 took place on May 21, 1998. In 2010, Boeing developed a modification of the Boeing 777-300 ER for extended range airlines. Boeing 777-300 ER aircraft were purchased by Emirates for flights to Russia. Emirates operates 86 Boeing 777 aircraft. The Boeing 777-300 was purchased by the following airlines: Air Canada, Singapore Airlines, Air France (the Boeing 777 Freighter model was produced for the French airline and is a cargo version of the Boeing 777),

Boeing 777F
The Boeing 777F is a cargo variant of the Boeing 777-200 ER. With a maximum load, a Boeing can fly over 9,000 kilometers. The Boeing Company plans to convert the first Boeing 777-200 and Boeing 777-300 aircraft into cargo variants under the Boeing Converted Freighter program and will have the designation Boeing 777 BCF.

The best seats in the Boeing 777 cabin

The best seats depend on the layout of the cabin. We can say about the general signs:
- it is better to buy seats at the emergency exit, there is more space,
- Comfort seats (from 11th to 16th row in Boeing 777-300),
- any seats in three chairs, but not in front of the toilet,
- relatively more favorable places near the aisle, you can stretch your legs for a while,
- when arranging the Boeing 777 according to the 2-5-2 scheme, when flying together, it is better to take paired ones from the window.
- in all Boeing 777 economy cabins - the closer the seat to the nose, the greater the distance between the rows.
- the biggest shaking is felt in the tail, the least at the wings,
- when the flight is not busy in the tail, it happens that there are no neighbors at all and there is more freedom than necessary.

- a long-range wide-body aircraft, is one of the largest twin-engine airliners in the world. The Boeing Company considers this aircraft the most consumer-oriented in the world, since airlines and passengers took part in its creation.

Story

In the early 1970s, demand for air travel was growing at a rapid pace and airlines were in dire need of large capacity aircraft. Thus, the first generation of wide-body aircraft was born: the Boeing 747, McDonnell Douglas DC-10 and Lockheed L-1011 TriStar. In 1978, after careful market research and airline requests, Boeing introduced three new designs: the economical twin-engine 757 (designed to replace the venerable Boeing 727), the long-haul twin-engine 767 (to challenge the Airbus A300), and the tri-engine 777 concept (to compete with DC-10 and L-1011). As a result, the models 757 and 767 successfully debuted, and the 777 project was curtailed until better times due to lack of demand.

By the end of the 1980s, the market situation had changed, old aircraft were losing their relevance, and airlines needed new, more economical ones. At the same time, Boeing conducted studies that predicted further growth in demand for wide-body aircraft. Thus, there was an urgent need to have an aircraft that would be in a niche between the Boeing 767-300ER and the Boeing 747-400.

Competitors also did not relax. McDonnell Douglas was preparing to replace the DC-10 with its extended MD-11 modification. Airbus has been working on the A330 and A340 family of wide-body aircraft.

Boeing 777 development

Initially, Boeing planned to take the 767 as a basis and redesign it, resulting in the concept of the so-called 767-X. It was in many ways reminiscent of the 767, but had an elongated fuselage, increased wing area and could carry about 340 passengers over a distance of up to 13.5 thousand kilometers.

However, the airlines were unhappy. They wanted an aircraft capable of flying not only intercontinental but also shorter distances, with a cabin configuration similar to the Boeing 747, which, moreover, could be changed by adding or removing the required number of seats in the cabin of one class or another. Another necessary condition was the reduction in operating costs - they would have to be significantly lower than those of the Boeing 767. As a result, the original design was significantly redesigned.

In 1988, Boeing presented the twin-engine Boeing 777 project. Airlines showed interest in it, and sales of the aircraft began in December 1989.

The design process for the 777 differed significantly from Boeing's past experience. For the first time in the firm's history, eight major airlines (All Nippon Airways, American Airlines, British Airways, Cathay Pacific Airways, Delta Air Lines, Japan Airlines, Qantas and United Airlines) were involved in the design of the aircraft, helping with recommendations. The process itself was the creation of a working group called "Working Together" ("Working Together"), the first meeting of which took place in January 1990. Airlines have created a list of recommendations based on their needs and passenger surveys.

In March 1990, the working group decided on the basic configuration of the aircraft: the cockpit should be unified with the Boeing 747, it should be equipped with liquid crystal displays and Fly-By-Wire control, the fuel efficiency of the aircraft should be 10% better than that of competitors (A330 and MD-11).

Further, Boeing admitted that thanks to this assistance, the 777 has become the most consumer-oriented aircraft in the world.

The production site for the Boeing 777 was the gigantic plant in Everett, Washington, the same one built in the mid-1960s to manufacture .

Of the interesting facts, it is also worth noting that it became the first commercial airliner, 100% developed on computers. For all the time of its development, not a single paper drawing was released, everything was made using a three-dimensional design system, now known as CATIA. The aircraft was pre-assembled in a computer, which made it possible to avoid a large number of errors during production.

On October 14, 1990, United Airlines became the first Boeing 777 customer. The airline placed an order for 34 aircraft (with an option for another 34 aircraft).

Production

The production process of the Boeing 777 involved an unprecedented number of subcontractors from around the world. Mitsubishi Heavy Industries and Kawasaki Heavy Industries supply the fuselage panels, Fuji Heavy Industries, Ltd supply the wing center section, Hawker de Havilland supply the elevators, Aerospace Technologies of Australia supply the rudder, etc.

In terms of engines, three companies offered their services: General Electric, Pratt & Whitney and Rolls-Royce. Each of the manufacturers took on the development of an engine with a capacity of 77,000 pounds (340 kN) and above.

To start assembling the 777, Boeing had to nearly double the size of its plant in Everett. It cost the company nearly $1.5 billion. Two assembly lines were built in the new areas, which allow the aircraft fuselage to rotate 180 degrees.

Assembly of the first Boeing 777 began on January 4, 1993. By that time, the aircraft received 118 firm orders from 10 airlines. The total investment in the program amounted to more than 4 billion dollars.

First flight and certification

On April 9, 1994, the first Boeing 777 with serial number WA001 was rolled out of the hangar. More than 100,000 guests gathered to see the first copy.

The Boeing 777 first flew on June 12, 1994, with Boeing Chief Test Pilot John E. Cashman at the controls. After that, an 11-month aircraft test program began, which, in comparison with previous models, was supposed to be the most intense.

On April 19, 1995, the aircraft was certified by the US Federal Aviation Administration (FAA).

The commercial operation of the aircraft began on May 15, 1995, when United Airlines took delivery of the first Boeing 777.

Around the same time, the airliner was certified under the ETOPS-180 rules (flight safety rules, according to which the route of a twin-engine aircraft must be laid within no more than 180 minutes of flight to the nearest airfield, where an emergency landing could be made in the event of an engine failure. ).

Production and modifications

Following the debut of the original model, Boeing began developing a version with increased takeoff weight and increased range. Initially, the model was given the name 777-200IGW (Increased Gross Weight - increased take-off weight), but later it was shortened to (Extended Range - increased range).

The first flight of the Boeing 777-200ER was made on October 7, 1996, and its commercial operation began on February 9, 1997 at the airline.

On April 2, 1997, a Boeing 777-200ER owned by Malaysia Airlines made a record non-stop flight from Seattle (USA) to Kuala Lampur (Malaysia), at a distance of 20,044 km, the flight lasted 21 hours and 23 minutes.

After the introduction of the 777-200ER, Boeing began developing an extended version. On October 16, 1997, he set off on his first flight. In general, before the appearance, 777-300 was the longest passenger aircraft in the world (total length - 73.9 m). Compared to the 777-200, the capacity has been increased by 20%. Commercial operation of the liner began on May 27, 1998 with Cathay Pacific.

On February 29, 2000, Boeing offered airlines the new 777-300ER, an aircraft with increased capacity and range. On February 24, 2003, the first flight took place, and its commercial operation began on April 29, 2004, in the airline.

The Boeing 777-300ER proved to be the best-selling model among all 777s, as it is comparable in capabilities to four-engine aircraft, but requires lower operating costs.

February 15, 2005, Boeing introduced another long-range modification (Long Range). The first flight of this model took place on March 8, 2005. And on November 10, 2005, the plane set a world record (included in the Guinness Book of Records), flying 21.602 km non-stop from Hong Kong (China) to London (UK). Flight time - 22 hours 42 minutes.

On May 23, 2008, Boeing unveiled a freighter version of the 777F (Freighter - “truck”), which was based on the 777-200LR. The first flight of the aircraft took place on February 6, 2009. The first buyer of the aircraft was Air France, which began its commercial operation on February 19, 2009.

Further developments

The Boeing 777 has become the second largest aircraft in the Boeing lineup, after the flagship 747. Moreover, the 777 has become the company's most profitable airliner. In 2000, the profit from its sales reached about 400 million dollars. In 2004, the aircraft brought in more revenue than the 747 and 767 combined. In 2007, orders for the second generation Boeing 777 reached 350 units, and in the same year, Boeing announced that all production facilities for the creation of the liner were occupied until 2012. Undoubtedly, this is a great success, but it was not without problems. In 2008, the 777 production program fell far behind schedule, with losses estimated at around $95 billion. In 2010, Boeing announced plans to increase production capacity from 5 aircraft to 8 by 2013. For reference, each 777-300ER takes 49 days to assemble.

In 2009, Boeing closely followed their development of the A350 XWB, which promises to be more fuel efficient than the 777 and 787. Subsequently, the aerodynamics and engines of the 777-300ER have been improved.

In September 2011, Boeing and General Electric released preliminary information about the next generation Boeing 777-8X and 777-9X. It is expected that the wingspan of the aircraft will increase from 64.8 meters to 71.3 meters. Thanks to the use of composite materials, the total weight of the aircraft should be reduced from 352,000 kg to 344,000 kg (for the 777-9X version).

Meanwhile, General Electric announced the development of a new GE9X engine. Its diameter will remain the same as the GE90-115B (325 cm), thrust will be 88,000 (390kH) for the 777-8X version, and 99,500 pounds (443 kH) for the 777-9X version.

Rolls-Royce and Pratt & Whitney did not stand aside, which also offered their services. In particular, the new RB3025 engine based on the Trent 1000 and Trent XWB structure as well as the PW1000G have up to 100,000 lbs (440kH) of horsepower.

To date, Boeing continues to explore the capabilities of the aircraft, and is developing an ultra-long range version based on the 777-200LR, which has received the working name of 777-8LX. The range of this model is 17,560 km (compared to 17,400 for the 777-200LR). The estimated length of the aircraft fuselage is 76.5 m, and the capacity is about 407 passengers. According to preliminary data, the commissioning of the 777-8LX is scheduled for 2019.

In November 2011, the assembly of 1000 copies of the 777-300ER owned by Emirates began. Its presentation took place in March 2012.

At the end of 2011, the FAA gave the 777 and 787 aircraft an overall type rating (Type Rating), thanks to the unification of the cockpits, pilots can gain qualifications working on both models.

In the future, it is possible that the 777 aircraft can be replaced by a new family of Boeing Yellowstone 3 liners, which is based on Boeing 787 technologies.

Aircraft systems

In the 777 project, Boeing introduced a number of advanced technologies, including: a fully digital fly-by-wire control system, fully programmable avionics, a glass cockpit (Glass Cockpit) with Honeywell liquid crystal displays, an avionics fiber optic network (which on a commercial aircraft was performed for the first time). At the same time, Boeing used already known developments from the canceled project of the Boeing 7J7 regional aircraft, which had a similar level of technology.

The Boeing 777 wing has a supercritical airfoil optimized for a cruising speed of Mach 0.83 (updated to Mach 0.84 after testing). The wing structure has a greater thickness and span than previous aircraft, which has increased the range and payload, improve flight performance and increase the cruising altitude. At the launch of the 777 project, it was proposed to develop a folding wing (Folding wingtips) so that airlines could use hangars for small aircraft, but no airline agreed to this option.

The Boeing 777 also has the largest landing gear and largest tires ever used in a commercial jetliner. Each tire from the 777-300ER's main six-wheel landing gear can carry a load of 27 tons, more than the tire load of a Boeing 747-400 aircraft.

The aircraft has three redundant hydraulic systems, of which only one is needed for landing.

An emergency aircraft turbine is located in the wing fairing under the fuselage - a small propeller that extends out of the aircraft in emergency situations to provide a minimum power supply.

fly-by-wire

The Boeing 777 is the first aircraft in the company's history to be equipped with a fly-by-wire control system. However, for the convenience of the pilots, it was decided to leave the usual steering columns. Along with the traditional steering wheel control system, the cockpit has a simplified layout that retains similarities with previous Boeing models.

The fly-by-wire control system is also equipped with flight parameter protection, which ensures that pilot movements on the control sticks do not exceed the set flight configuration limits. Also, the system prevents dangerous maneuvers. True, in case of emergency, the system can be turned off at the command of the pilot, if it is deemed necessary.

Salon

The cabin of the Boeing 777 is designed in the style of the Boeing Signature Interior, it has enlarged luggage racks and indirect lighting. Seat configuration ranges from 4 in a row of first class to 10 in economy class. The 380x250mm window size was the largest of any commercial airliner until the introduction of the 787. The cabin layout allows airlines to quickly move seats, galleys, and lavatories to suit their desired configuration. Some aircraft are equipped with VIP lounges for charter flights. Of the features, the development of Boeing engineers deserves special attention - a new hydraulic hinge of the toilet lid, which closes slowly.

On July 7, 2011, it was reported that Boeing had decided to replace the Signature Interior in the 777 with a new interior from the 787, as part of Boeing's all-aircraft unification program.

Comfortable working conditions for the crew

In 2003, as an option for the 777, Boeing introduced crew rest areas. They are located above the main cabin and are equipped with ladders. Seating consists of two seats and two beds in the front of the fuselage, as well as several seats in the rear of the fuselage. In general, similar solutions are also used on other narrow- and wide-body Boeing models, including, and new modifications.

Boeing 777 in all modifications is a long-haul airliner capable of serving non-stop commercial flights up to 18 hours. However, the rules of various aviation regulators, professional and trade union organizations limit the continuous work of the crew and cabin crew. For the rest of pilots, seats are usually reserved in business class or special containers are installed in the luggage compartment, equipped with berths and communication with the cockpit and cabin of the aircraft. Unfortunately, such solutions reduce the passenger capacity or the volume of cargo carried. Therefore, Boeing proposed an original solution - to use the space between the luggage racks and the fuselage for this purpose (English-speaking engineers call this part of the aircraft the “crown”).

On Boeing 777-200ER, −200LR and −300ER aircraft, a pilot rest compartment is installed in the front of the aircraft above the first class cabin. It includes two comfortable armchairs, 2 or 3 beds separated by partitions, a wardrobe, a TV set and a washbasin. The entrance to this compartment is via the stairs located at the door number 1 (front left door). This solution allows you to free up from 4 to 7 seats in business class.

Places for rest of flight attendants are also equipped in the space between the passenger compartment and the fuselage, but in the rear of the aircraft. On modifications -200ER and -200LR, the entrance is via a staircase in the central part of the aircraft, and the compartment itself is designed for 6 or 7 flight attendants. In the −300ER modification, the airline can order a compartment with a capacity of 6 to 10 people. Entrance, depending on the number of seats, is carried out through the door, either in the central part of the aircraft (6-7 seats) or in the tail (8-10 seats). The compartment is equipped with berths, lighting and communication with the salon.

The installation of crew rest areas required a reconfiguration of the cabin space, rerouting of cables and lines, and even the development of some new systems.

In the 777F cargo modification, the entire internal space of the fuselage is completely occupied by cargo compartments, so 4-5 comfortable seats are provided behind the cockpit for crew rest and couriers.

Boeing 777 modifications

777-200

Boeing 777-200 - became the first aircraft in the 777 family. Basically, this modification was focused on US airlines. Throughout history, 88 777-200s have been produced. Commercial operation of the liner began with United Airlines on May 15, 1995. The aircraft's main competitor is the Airbus A330-300.

777-200ER

The Boeing 777-200ER, compared to the basic modification, has additional fuel tanks, as well as increased takeoff weight. The main purpose of the aircraft is transatlantic flights. The maximum flight range is 14,260 km.

The first 777-200ER was handed over to British Airways on 6 February 1997. The main competitor of the liner is the Airbus A330-300.

777-200LR

The Boeing 777-200LR is the longest-range aircraft on the planet. Boeing called this model the "Worldliner," referring to the airliner's ability to connect virtually any two airports. The modification set a world record for the longest non-stop flight among commercial airliners. Flight range - 17.370 km. In a word, the modification is designed for extra-long flights.

The aircraft was developed almost simultaneously with the 777-300ER. The Boeing 777-200LR has an increased maximum takeoff weight and three additional fuel tanks in the rear luggage compartment. Other distinguishing features are new wingtips, new undercarriage legs and a reinforced airframe. The first 777-200LR was handed over to Pakistan International Airlines on 26 February 2006. The main competitor of the liner is.

Boeing 777-300 - is a modification extended by 11 meters. Thanks to this, the aircraft is able to accommodate up to 550 passengers in a single-class configuration. Initially, it was intended to replace the obsolete Boeing 747-100. Compared to the older 747, the 777-300 has a similar passenger capacity and range, but consumes a third less fuel and has 40% lower operating costs.

The long length of the 777-300 forced the developers to provide a special ski under the tail to protect it from hitting the ground, as well as chambers for easy maneuvering on the platform. The maximum flight range is 11,120 km, which makes it possible to serve heavily loaded routes, which were previously handled only by the Boeing 747.

The first 777-300 was handed over to Cathay Pacific on May 21, 1998. By and large, among Airbus aircraft there is no competitor for the 777-300, however, it is usually called.

777-300ER

Boeing 777-300ER is a modification with increased maximum takeoff weight and capacity. The aircraft has extended wingtips, new main landing gear, a reinforced nose strut and additional fuel tanks. Also, in the 777-300ER, the fuselage, wings, plumage and engine pylons were redesigned. Standard on this model, the GE90-115B turbofan engines are by far the most powerful jet engines in the world, with a maximum thrust of 513 kN.

The range of the 777-300ER fully loaded is increased by approximately 34% compared to the 777-300. The maximum flight range of the Boeing 777-300ER is 14,690 km.

The first 777-300ER was handed over to Air France on April 29, 2004. The main competitor is the Airbus A340-600. However, due to the two engines, the 777-300ER is 8-9% more economical than the A340-600, which has 4 engines. Compared to the 747-400, the 777-300ER has 20% less fuel consumption.

Boeing 777F - cargo modification. The aircraft inherited the airframe and engines from the 777-200LR modification, and the fuel capacity was the same as that of the 777-300ER modification. The maximum payload of 103t makes the 777F a direct competitor to the 747-200F (110t). With maximum load, the aircraft has a range of 9047 km. With a decrease in load, the range can be increased. Since the aircraft has better performance compared to existing cargo aircraft, airlines plan to replace the aging 747-200F and MD-11F with the 777F modification.

- a family of wide-body passenger aircraft for long-haul airlines. Aircraft of the family are among the largest passenger aircraft.

The Boeing 777 is a twin-engine turbojet low-wing swept-wing aircraft with a single-fin tail.

It is the first aircraft completely designed without paper drawings, but only using 3D computer graphics.

The first Boeing 777-200s entered service with United Airlines in 1995. Later, extended-range versions of the Boeing 777-200ER (extended range) and Boeing 777-200LR (longer-range) were also released.

In 1998, the Boeing 777-300 aircraft entered the air lines of Cathay Pacific Airways, differing from the previous model in an elongated fuselage and increased passenger capacity. Since 2004, a longer-range version of the Boeing 777-300ER has also been produced.

Based on the Boeing 777-200LR Worldliner aircraft, a cargo modification of the Boeing 777 Freighter has been developed and is being produced.
Currently, the Boeing Corporation is developing an upgraded version of the aircraft under the symbol Boeing 777X, which will be equipped with new engines and a composite wing.

The Boeing 777-200 is an aircraft for carrying 300-400 passengers over a distance of up to 6,000 kilometers (basic version), 11,000 kilometers (777-200ER) and 14,000 kilometers (777-200LR).

Boeing 777-300 (Boeing-777-300) - version with an extended fuselage, accommodating up to 450 passengers, flight range from 7 thousand to 10 thousand kilometers (in the 777-300ER version).

The cockpit is equipped with an Electronic Flight Bag (EFB) system. The data of the EFB system, necessary for pilots to control the aircraft, has been transferred to electronic form, which makes it easier to work with them.

In addition to the Electronic Flight Bag system, a number of solutions have been introduced on board the Boeing 777 to improve passenger comfort. In particular, the cabin is equipped with a video system with screens built into the backs of the seats, and the seats in the business class cabin have reclining ergonomic backs.

The aircraft is equipped with the Matsushita System 3000i, which provides storage for more than 300 hours of video and audio recording, played back at the request of passengers.

An important advantage of the Boeing 777 compared to other modern airliners is the use of a variety of light but strong alloys and composite materials in its design. Passenger cabin floor beams, aerodynamic fairings and other parts are made of composite materials. The total share of composite materials in the total weight of the entire aircraft structure is nine percent. Thus, the weight of the aircraft and the cost of its production are significantly reduced.

Boeing 777s are part of the fleets of the world's largest airlines, including British Airways, Air France, Alitalia, Lauda Air and El Al.

One of the largest passenger aircraft over the past 20 years in Russian and world aviation is the Boeing 777. It is also called the Boeng T7, which means Triple Seven, or "Three Sevens".

The largest number of these airliners is operated by Transaero (14 aircraft) and Aeroflot (16 aircraft).

The layout of the Boeing 777 cabin, the best places for flights, technical specifications - all this is in this article.

Short description

This Boeing model is the very first in history, its design was developed in the 90s of the last century without paper drawings, entirely on a computer using special programs.

This is the most reliable airliner in the history of aviation, which makes long flights without a single stop.

"Boeing 777" belongs to the wide-body passenger aircraft. It has been in operation since 1995 to the present day.

The capacity is 305-550 people, the flight range is 9,100-17,500 kilometers.

Specifications "Boeing 777"

It is the largest airliner in the world with only 2 engines. These are powerful gas turbine engines "General Electric". Landing gear consists of 6 wheels, which distinguishes it from other aircraft.

Consider the technical characteristics of the Boeing 777 for modifications 200 and 300.

Interior and cabin scheme

"Boeing 777", as noted above, has several varieties. Salons, each of the modifications has 3 or 4 - each has its own layout, which directly depends on the customer.

The interior of the saloons is dominated by curved lines, indirect lighting, wide luggage racks. The size of the porthole relative to the earlier ones is 380x250 mm.

Economy class capacity - up to 555 people. Armchairs are arranged 10 in a row. Compared to the first models of the Boeing 777, since 2011 the interior has been modernized, making it more modern.

In business class, the seats are arranged 6 in a row, and they fold out into a full bed, which is very convenient during long-haul flights. Due to the fact that the total number of seats is less than in economy class, there is more space here.

Imperial class is designed for the most comfortable and expensive flights. Increased attention, additional services, the best cuisine - all this for special guests.

The layout of the Boeing 777-300 cabin of Aeroflot airlines is shown in the photo below.

The best seats on the plane

Depends on the overall staffing of the cabin. When buying tickets, you can choose any seats, but it is preferable to find the most convenient ones so that the flight is pleasant and comfortable.

The best seats are located at the emergency exits: there is extra legroom. Convenient seats in the Boeing 777-300 are those located in rows 11-16 - these are places where 3 chairs are installed in a row (except those next to the toilet). Good places are located near the aisle - there is an opportunity for a short while, but with pleasure to spread your legs.

- if the modification provides for double seats near the porthole, then when flying in pairs it is better to choose them;

In economy classes, the closer to the nose of the aircraft, the wider the distance between the rows of seats;

Those who are in the tail shake most of all, least of all - near the wings;

If the airliner is not fully loaded with passengers, then there are fewer people in the tail and, accordingly, more space.

Of course, these are average figures, since different airlines have their own nuances in the design of the cabins of their aircraft, and it does not matter that in fact this is the same Boeing 777.

"Transaero"

The Russian aviation company Transaero owns 14 Boeing 777 aircraft. Of these, 9 are modifications of the Boeing 777-200.

This company uses configurations with a passenger capacity of 306 and 323 people, 4th and 3rd class cabins, respectively.

On a passenger aircraft, there are usually only 3 classes. But the air travel company supplements the standard set with additional subclasses.

In Transaero they are as follows:

Imperial;

Business class (premium);

Economic;

Tourist.

A photo of the layout of the cabin "Boeing 777" ("Transaero") modification 200 is presented below.

In the imperial class, all seats are as comfortable as possible for flights. There are only 12 seats in the cabin, which can be transformed into a bed if necessary and desired. Near each seat there is a liquid crystal screen and a table for eating or working on a PC. Access to the bathroom directly from the salon.

Business class (premium) contains 14 soft and comfortable seats in the cabin. But in the fifth row there are seats, the backs of which recline limitedly.

Economy class is a spacious cabin with a large number of comfortable seats.

There are several places here that are not as convenient as the rest: near bathrooms, near partitions and emergency exits (10th, 29th rows). The backs of these chairs are limited in reclining.

Tourist class is a type of economy class. There are many convenient places (for example, in the 30th row, A, B, H, K). Less comfortable are places C, D, E, F, G in the 30th row, 42nd and 43rd rows at the end of the cabin.

Aeroflot

The Boeing 777 of this airline sends modification 300 for long-distance flights. The passenger capacity of these liners is about 400 people, 3 cabins, 3 classes:

Comfort;

Business class is located at the nose of the aircraft. There are 30 armchair-beds in the salon, which are arranged according to the "two-two-two" scheme. The cabin has its own improved menu, drinks, internet, a retractable table for working at a PC, the ability to charge a mobile phone or computer, and an individual approach to passengers.

The comfort class cabin is designed for 48 seats. This is the 11th-16th rows. Comfortable seats with a width of 49 cm allow you to fly in comfort. Near each chair there is a retractable footrest, which makes it possible to recline. There is individual lighting, a table, a monitor, a socket for charging a mobile phone. In the 11th row there is a fastener for a baby cradle. You can pre-order baby food separately. Not the most convenient places of this class are located near the toilet.

The economy class is the most crowded, the passenger capacity is 324 people. Armchairs are arranged according to the scheme "two-four-two". For each passenger, Aeroflot provided a blanket, pillow, slippers, and a sleep mask. There is a monitor to brighten up the flight while watching a movie or listening to music. It is possible to use the Internet for an additional fee. Seat width - 43 cm. In the 17th, 24th, 39th rows there are attachments for the cradle. You can ask for games and books for children - this is provided by the services of the airline.

It is the world's largest twin-engine jet passenger aircraft. The Boeing 777 has set an absolute distance record for passenger aircraft: 21,601 thousand km! Boeing 777 ("Triple Seven" or "three sevens") - this aircraft was developed in the early 1990s, made its first flight in 1994, and has been in operation since 1995. The Boeing 777 was the first commercial airliner to be 100% computer-generated. And this is the safest long-haul airliner in the history of aviation!

I flew three sevens only once - from Dubai to Male with the Emirates airline, and then I was surprised to learn that they saved a lot on the layout of the economy class cabin, we will put one additional seat in the row, reducing the width of the rest! In this report, I will talk about the history of creation, design features and show the passenger cabin of the largest operator of this type of aircraft in Russia.

History of creation:

In the mid 1970s. Three-engined 777, which was conceived as a competitor for the McDonnell Douglas DC-10 and Lockheed L-1011. This aircraft was conceived as a modified version of the 767 with a redesigned wing and tail section. It was planned to create two main options: a short-haul aircraft that would be able to carry up to 175 passengers over a distance of 5,000 kilometers, and an intercontinental liner carrying the same number of passengers over a distance of 8,000 kilometers.

Work on twin-engined aircraft soon began, but the 777 project was shelved due to difficulties with the design of the tail of the aircraft, and the company also decided to focus on the more commercially promising 757 and 767. As a result, when both machines began to roll off the assembly line, it became it is clear that a link is missing in the line of Boeing aircraft. There was an urgent need to have an aircraft that would be in a niche between such machines as the Boeing 767-300ER and Boeing 747-400.

Initially, Boeing planned to simply refine the 767, resulting in the concept of the so-called 767-X. It was in many ways akin to the 767, but had a longer fuselage, larger wing, and could carry about 340 passengers for distances of up to 13,500 kilometers.

1.

But the airlines were not impressed with the new aircraft. They wanted to have an aircraft capable of flying shorter distances and with a cabin configuration similar to the Boeing 747, which, in addition, could be changed by adding or removing the required number of passengers in the cabin of one class or another. Another necessary condition was the reduction in operating costs - they would have to be significantly lower than those of the 767. As a result, the original design was heavily revised and the twin-engine Boeing 777 was born.

The Boeing 777 was the first commercial airliner to be 100% computer-generated. During the entire development period, not a single paper drawing was released, everything was made using a three-dimensional design system.

The development of the aircraft began in 1990 and immediately received the first order from United Airlines. In 1995, the first 777 began operating commercial flights. To date, the 777-200LR is the aircraft capable of making the longest passenger flights in the world.

2.

Modifications:

The 777-200 was the first modification of the aircraft and was intended for Segment A. The first 777-200 was transferred to United Airlines on May 15, 1995. With a range of 5235 nautical miles, the 777-200 modification was focused primarily on US domestic carriers. A total of 88 different aircraft of the 777-200 modification were handed over to ten customers. Airbus' competitor is the A330-300.

4.

An extended version of the 777-300 was intended to replace the Boeing 747-100 and Boeing 747-200 aircraft. Compared to older versions of the 747, the extended version has a similar passenger capacity and range, but consumes a third less fuel and has 40% lower operating costs. The fuselage of the 777-300 is 11 meters longer than the base 777-200, allowing up to 550 passengers to be accommodated in a single-class configuration. The maximum modification range is 6015 nautical miles, which allows the 777-300 to serve the heavily loaded destinations previously served by the 747.

777-200ER

Modification 777-200ER ("ER" stands for Extended Range, increased range). The 777-200ER has increased fuel capacity and maximum takeoff weight compared to the 777-200 modification. Designed for international carriers and transatlantic flights, the nf modification has a maximum range of 7700 nautical miles (14260.4 km).

777-200LR

777-200LR ("LR" stands for "Longer Range" - long range), a model for Segment C, in 2006 became the most "long-range" commercial airliner in the world. Boeing called this model Worldliner, indicating the ability of an airliner to connect almost any two airports. The modification set a world record for the longest non-stop flight among commercial airliners - the flight range is 9,380 nautical miles (17,370 km). Modification 777-200LR is designed for extra long flights, such as Los Angeles - Singapore or Dallas - Tokyo. The 777-200LR has an increased maximum takeoff weight and three additional fuel tanks in the rear luggage compartment.

777-300ER

The 777-300ER ("ER" stands for Extended Range) is a modification of the 777-300. The modification has bevelled and elongated wingtips, new main landing gear, reinforced front strut and additional fuel tanks. Standard on this model, the GE90-115B turbofan engines are by far the most powerful jet engines in the world, with a maximum thrust of 513 kN. The maximum range is 7,930 nautical miles (14,690 km), made possible by increased maximum takeoff weight and fuel capacity. The range of the 777-300ER fully loaded is increased by approximately 34% compared to the 777-300. After flight tests, the introduction of new engines, wings and an increase in takeoff weight, fuel consumption decreased by 1.4%.

And all the modifications in the visual range:

A good illustration for comparing scales is ahead of the 737th. Please note that the diameter of the GE-115B engine installed on the 777 is only 30 cm smaller than the width of the Boeing 737 cabin!

11.

Design elements:

The design of the airframe includes the use of composite materials, which make up 9% of the weight of the structure. From such materials are made, including the floor of the cabin and the steering wheels. The main part of the fuselage has a circular section and at the rear passes into a blade-like tail cone, in which the auxiliary power unit is located.

The airliner also has the largest landing gear and largest tires ever used in a commercial jet airliner. Each tire on the 777-300ER's six-wheel main landing gear can carry a load of 27 tons, more than the tire load of a Boeing 747-400!

20.

The aircraft has three redundant hydraulic systems, of which only one is needed for landing.
An emergency aircraft turbine is located in the wing fairing under the fuselage - a small propeller that extends out of the aircraft in emergency situations to ensure minimal power supply.

The General Electric GE90 engines on the Boeing 7777 are the largest and most powerful jet engines in aviation history.

And all five Boeing 777-300s of Transaero Airlines are equipped with Rolls Royse RR211 Trent 892 engines:

Cockpit:

The cockpit is very spacious. Boeing 777 in all modifications is a long-haul airliner capable of serving non-stop commercial flights up to 18 hours. However, the rules of various aviation regulators, professional and trade union organizations limit the continuous work of the crew and cabin crew.

Interior:

The interior of the 777, also known as the Boeing Signature Interior, features curved lines, oversized luggage racks and indirect lighting. Seat configuration ranges from 4 in a row in first class to 10 in economy class. The size of the windows - 380 × 250 mm - was the largest of all commercial airliners before the introduction of 787.

The passenger cabin of each airline has its own layout. It depends on certain requirements of the customer, and not on the type of aircraft!
Please note that in the economy class, Transaero has one seat less in a row than, for example, Emirates (!) and Aeroflot. And this means that the seats themselves are wider and more comfortable!

Examples of the layout of the Boeing 777 -200 and -300 a / c Transaero:

Let's take a look at the Boeing-777-300 of Transaero Airlines. EI-UNM flew with Singapore Airlines, transferred to Transaero in 2012. The salon is completely updated, the Lumexis entertainment system is installed everywhere. The upholstery uses wear-resistant Alcantara material, and the seat manufacturer is the Italian company Aviointeriors.

Safety:

This liner is considered the safest aircraft among all long-haul liners. The Boeing 777 has had eight accidents in its 18 years of operation, including one crash and two hijack attempts. On July 6, 2013, the first fatal air crash occurred. An Asiana Airlines Boeing 777-200ER flying from Seoul to San Francisco crashed while landing at San Francisco Airport, hitting the end of the runway with its tail. 2 people died.

Boeing 777 in Russia:

In Russia, the largest operator of Boeing 777 aircraft is Transaero. The fleet of this company has 14 aircraft: 5 - Boeing 777-300, 9 - Boeing 777-200ER. In addition to Transaero, this aircraft is in the fleet of Aeroflot, Nordwind and Orenair.
