Boeing 767（Boeing 767）It's the United StatesThe Boeing CompanyMedium and large, long range, wide body twin engine jet aircraft developed for use withAirbusA300 and A310 compete.It's the first Boeing aircraft with two crew membersGlass Cockpit The aircraft.Boeing 757The cockpit design of the 767 is the same as that of the 767. It is easy for the crew and maintenance personnel to master both aircraft at the same time.767 and 757 are the first two person cockpit in Boeing's civil aircraft, and also the first electronic aircraft in Boeing's passenger aircraftFlight instrument。The first model of 767 is - 200, and then the longer model - 300 is produced.There are also 400 models planned for abortion. In addition, there are - 200ER, - 300ER and - 400ER for long-distance use.
Boeing 767yesThe Boeing CompanyProduction of double engines (engines), half wide body, medium and long distance transport aircraft.The cabin of the Boeing 767 adopts a dual channel layout, which is mainly oriented to the 200-300 seat market, and is used to connect with theAirbus A300/A310 series competition, mainly for the 1980sBoeing 707、DC8、DC10、Boeing 727Such as the market formed by the retirement of 200 seat medium and long range passenger aircraft.Boeing 767 series is between the size of single channelBoeing 757And larger dual channelBoeing 777between.[1]
In April 1980, the first Boeing 767 left the factory. On September 26, 1981, the first Boeing 767 flew for the first time. In July 1982, the model certificate was delivered in September of the same year, and it was used for commercial flight for the first time in December of the same year.In 1990-1992, the delivery quantity was 60, 62 and 63 respectively, reaching the peak.Boeing originally planned to stop production of the 767 series at the end of 2007, but it received 27 orders for 767 freighters in March 2007, so the stop production plan was delayed.
In 1985, China first introduced this model, and on May 6, 2014, Air China sold the last oneBoeing 767-300ER。Its sale announced the completion of the Boeing 767 fleet inAir ChinaAnd formally withdrew from the historical stage.[2]
On December 5, 2018, the last 767 aircraft in the domestic fleet was retired.[3]
In 1970,Boeing 747It became the first wide body jet to enter service.The 747 is the first aircraft wide enough to have a dual aisle cabin.Two years later, the manufacturer began a development study, code named 7X7, to replace the 707 and other early generation narrow body aircraft with new wide body aircraft.The aircraft will also provide dual channel seats, but the fuselage is smaller than the existing 747,McDonnell Douglas Douglas DC-10andLockheed L-1011The three-star wide body is smaller.In order to pay high development costs, BoeingItalyCompany Aeritalia andJapanTransport Development Corporation (CTDC), a consortium of aerospace companies, signed a risk sharing agreement.This marks the manufacturer's first majorInternational joint ventureAs a result, Aeritalia and CTDC received the supply contract in exchange for their early participation.The original 7X7 was considered as a short takeoff and landing aircraft for short distance flight, but customers were not interested in this concept, which led to its redefinition as a medium-sized, transcontinental aircraft.At this stage, the proposed aircraft has two or three engines, and possible configurations include an outboard engine and a T-tail.
By 1976, the layout of a twin jet aircraft was similar to that inAirbus A300It made its first appearance on, becoming the baseline configuration.The decision to use two engines reflects the industry's increasing interest in the new generationJet engineReliable and economical confidence.Although the airline requirements for the new wide body aircraft are still unclear, the 7X7 generally focuses on the medium and high-density market.Therefore, it intends to transport a large number of passengers between major cities.Advances in civil aviation technology, including high bypass ratioturbogenerator, new cockpit system,aerodynamicsImproved and lighter building materials were applied to the 7X7.Many of these functions are also included in a new medium-sized narrow body airliner, code named 7N7, which will become a parallel development work of the 757.The work of these two proposals was realized through the rise of the aviation industry in the late 1970s.
In January 1978, Boeing announced a large-scale expansion of the Everett plant, and then committed to producing 747 to adapt to its new wide body series.In February 1978, a new jet aircraft was named 767, and three variants were planned: a 767-100 with 190 seats, a 767-200 with 210 seats, and a Trijet 767MR/LR version intercontinental route with 200 seats.767MR/LR was later renamed 777 for differentiation purposes.767 was officially launched on July 14, 1978, whenUnited AirlinesOrdered 30 of the 767-200 models, and thenAmerican AirlinesandDelta Air Lines Orders were placed for 50 other 767-200 models.The 767-100 was not sold because its capacity was too close to 757, and the demand for the 777 triple row jet was finally reduced due to the standardized dual jet configuration.[2]
Boeing put forward a plan in 1972 to cooperate with Italy and Japan to produce a three engine long range aircraft, initially named 7X7, but this plan was not realized.faceoil crisis Impact, for the first twin engine wide body airliner——Airbus A300After scheme demonstration and market research, Boeing announced to launch the Boeing 767 development plan in February 1978. In July of the same yearUnited Airlines30 confirmed orders,United AirlinesRepresentatives participated in the whole design process to better meet the requirements of users.At the beginning of 1979, after obtaining 80 orders and 79 intended orders, we began the comprehensive design and development work.The Boeing 767 development cost was 1.5 billion US dollars (1978).[1]
Boeing 767International cooperation is adopted in the development and production plan,The Boeing CompanyIt is mainly responsible for the final assembly of aircraft,Japan Civil Transport Aircraft Department(composed of Mitsubishi, Kawasaki and Fuji Heavy Industries) andAlenia, ItalyParticipated in the Boeing 767 Program and undertook 30% of all development costs and workload.In the production of Boeing 767, Boeing mainly undertakes the final assembly of aircraft.The division of labor in Japan is as follows:mitsubishi heavy industries Responsible for the production of rear fuselage panels, purlins, passenger and cargo doors and vertical tails;Kawasaki Heavy IndustriesBe responsible for the beam rib between the middle fuselage wall plate and the wing;Fuji Heavy IndustriesBe responsible for rectifying the wrapping andMain landing gearHatch;ItalyAleniaProduction of composite wingtips, nose radomes and all moving control surfaces.Boeing subcontracts the middle section of the wing and its lower half fuselage and fuselage spacer toGrumman；Flat tail subcontracting toWalter Company；The tail of the fuselage is subcontracted toCanadian Aircraft Corporation；The horizontal tail was subcontracted toLin Tanke Watt Company。[1]

Airborne equipment adopts automatic flight state control system, engine data display and warning system, and all engine data are displayed digitally;HoneywellInertial Coordinate System, DigitalAtmospheric data computer。numberFlight management system, three redundant digital flight control computer, including FCS-700 flight control system, EFIS-700 electronicFlight instrumentSystem and RMI-743 wireless electromagnetic display.Optional equipment includes Boeing'swind shearDetection and guidance system.Boeing 767Double engine extended flight(ETOPS) performed well. In May 1985,FAA(FAA) approved that the distance between Boeing 767 and alternate airport in long-distance flight can be up to 120 minutes, that is, 120 minutes ETOPS.In March 1989, it was the first to be approved by the Federal Aviation Administration for 180 minute ETOPS.In this way, Boeing 767 can fly more trans Pacific and trans Atlantic routes from the United States.[4]
As the internal diameter of the Boeing 767 is only 4.7 meters, which is the narrowest in wide body airliners, its comfort is not as good as5.64m of Airbus A300。The cargo compartment is also small, which can only accommodate the conventional aviation use of narrow body aircraftLD2 containerIt is not allowed to use the commonLD3 container。Finally, Boeing 767Airbus A300In the competition, it gave up the leading position in the market of intermediate twin engine airliner.[4]
The Boeing 767 series includes three basic models:Boeing 767-200、Boeing 767-300andBoeing 767-400(ER), the difference is mainly in the length of the fuselage. The basic model - 200/- 300 corresponds to an Extended Range (ER)767-300EROn the basis of this, we have also developed and produced cargo models.The difference between the three passenger models of 767 is mainly in the length of the fuselage767-2006.43m long;767-400 is 6.43m longer than 767-300.Boeing 767 can select four, five, six, seven or eight passenger cabin layouts in each row according to operational needs.The passenger capacity depends on the cabin layout:Boeing 767-200ERIt can carry 181 passengers in the third class cabin layout ofBoeing 767-400ERIt can carry up to 375 passengers in the high-density charter plane layout.The cabin design of the 767-200/- 300 and - 400 delivered recently has learned fromBoeing 777The style of.

From 1985 to 2000, Air China successively introduced 16Boeing 767With the increase of operating hours, the Boeing 767 aircraft has entered the heavy maintenance stage. From 1995 to 2000, the joint venture Ameco has carried out the highest level maintenance for the Boeing 767 aircraft - 2S4C inspection and modified the engine reverse thrust synchronous lock for the first time;Major structural repair;Hanger modification, etc., created many world civil aviation and China's civil aviation first at that time.[6]
On October 18, 1995, Ameco implemented the engine reverse synchronous lock modification for the Boeing 767 aircraft for the first time. The most involved in this modification was the modification of the aircraft circuit system. More than 500 lines were modified, and 1300 functions were debugged. At that time, Meng Xianggui, the captain of the squadron, served as the general coordinator of the construction. He said that the modification team worked 12 hours a day. In order to ensure the progress, he gave up rest at the weekend.During this period, the aircraft had been working in and out of the 747 hangar for five days in the open air. The narrow electronic cabin was used for line modification. In some places, it was very difficult to turn and squat, so they had to bend down. However, when they put themselves into work, they forgot all the hardships and tiredness.[6]
On October 31, 1995, after 630 power on tests and modifications, Mr. Hodgson, a Boeing representative present, said that I participated in this project for 23 times, and only Ameco succeeded in one power on test. You have created the world's first and China's first.[6]
