Since 195 1 was formally established, Shen Fei Group Company has created one after another "firsts" in the aviation history of China: it successfully trial-produced the first jet fighter in China, the J-5 aircraft; The first jet trainer J-I aircraft: the first supersonic fighter-J-6 aircraft; The first surface-to-air missile-Hongqi-1 missile; The first two-speed fighter-J-7.
The first self-designed high-altitude high-speed fighter-歼 8 aircraft; The first supersonic fighter trainer-JH -6 aircraft; The first high, medium and low-altitude reconnaissance plane-歼 6; The first aircraft with good all-weather high-altitude and high-speed maneuverability-歼 8 Type II aircraft; The first receiver at the top of the tower. Over the past 50 years, Shen Fei Group has successively developed and produced more than 20 types of thousands of aircraft, which has made great contributions to the development of China's aviation industry and the modernization of national defense, and is known as the "cradle of China fighters".
Cheng Fei (Group) Co., Ltd., founded in 1958, was transformed into Chengdu Aircraft Industry (Group) Co., Ltd. in 1998. It is an important base for the design, development and mass production of fighters in China and has the ability to develop a new generation of fighters (J- 10A/B). Chengdu Aircraft Industry (Group) Co., Ltd., referred to as Cheng Fei (Group) Company, code 132 Factory, is a super-large enterprise directly under China Aviation Industry Corporation I, and an important base for developing and producing fighter planes in China.
Since 1978, the company has been making profits for many years, and has successively won the honorary titles of National May 1st Labor Award, National Advanced Unit for Creating Spiritual Civilization, National Excellent Enterprise for Ideological and Political Work, AAA Enterprise with China Corporate Image, and First National Excellent Corporate Culture Award-winning Unit.
Xifei Group Company has developed and produced more than 20 types of military and civil aircraft in the past 40 years. Military aircraft mainly include "Flying Leopard of China" and Bomb Six series aircraft. Among them, 30 planes of 5 models participated in the military parade of the 50th anniversary of the National Day. Civil aircraft mainly include Yun Qi series aircraft and Xinzhou 60 aircraft. Among them, Xinzhou-60 aircraft is the first aircraft designed, produced and tested in strict accordance with CCAR-25 in China, which is in line with international standards.
In terms of safety, reliability, comfort, economy and maintainability, it has reached or approached the level of similar advanced regional aircraft in the contemporary world. From 65438 to 0980, Xifei Group took the lead in going abroad and cooperated with world-renowned airlines such as the United States, Canada, Italy, France and Germany to produce aviation products.
The foreign aviation components produced by Xifei Group mainly include American Boeing 737-700 vertical tail and 747 assembly, door and wing box of Air France passenger plane, CL4 15 assembly of Air Canada, ATR72 aircraft of Alitalia 16 section, etc. Non-aviation civilian products mainly include "Xiwo" luxury passenger cars, "Xifei" aluminum profiles, metal hanging plates, aluminum doors and windows series products, VCM plastic-coated plates, variable frequency fuzzy controllers, compact shelves, anti-static floors and so on.
Main projects: coach aircraft, attack aircraft, agricultural and forestry aircraft, coastal defense products, projectile looms, motorcycles and engines. Nanchang Aircraft Manufacturing Company has produced several classic models: Qiang -5 single-seat double-engine supersonic attack aircraft, developed by Nanchang Aircraft Manufacturing Company; K-8 trainer, developed by China Nanchang Aircraft Manufacturing Company in cooperation with foreign countries, mainly exported; And the advanced trainer L- 15 Falcon developed by Nanchang Hongdu Aviation Industry Group (Haig).
From the first flight of Jiao -5 in 1954 to now, the military aviation manufacturing industry in China has developed for more than 60 years. At present, it has the production capacity of various types of military aircraft and the latest generation, making it the second country after the United States to independently develop five-generation aircraft at the same time.

Brief introduction of aircraft structure
Main components and functions of flight Up to now, except for a few special types of aircraft, most aircraft are composed of five main parts: wing, fuselage, tail, landing gear and power plant:
1, wing
The main function of the wing is to generate lift to support the flight of the aircraft in the air, and at the same time, it also plays a certain role in stability and control. Generally, ailerons and flaps are installed on the wing. The aileron can make the plane roll, and lowering the flap can increase the lift. The engine, landing gear and fuel tank can also be installed on the wing. The shape and size of airplane wings are different for different purposes.
2, the fuselage
The main function of the fuselage is to load passengers, crew, weapons, goods and various equipment, and connect other parts of the aircraft such as wings, tails and engines into a whole.
3. Tail wing
The tail includes a horizontal tail and a vertical tail. The horizontal tail consists of a fixed horizontal stabilizer and a movable elevator. Some high-speed aircraft combine horizontal stabilizer and elevator with full-motion horizontal tail. The vertical tail consists of a fixed vertical stabilizer and a movable rudder. The function of the tail wing is to control the pitch and deflection of the aircraft and ensure that the aircraft can fly smoothly.
4. Landing gear
The landing gear of aircraft is mostly composed of shock-absorbing struts and wheels, which are used to support aircraft during takeoff and landing, ground taxiing and parking.
5. Power plant
The power plant is mainly used to generate tension and thrust to make the plane move forward. Secondly, it can also provide power for other electrical equipment on the plane. At present, the widely used aircraft power devices are: aviation piston engine plus propeller, turbojet engine, turboprop engine and turbofan engine.
In addition to the engine itself, the power plant also includes a series of systems to ensure the normal operation of the engine. In addition to these five main parts, the aircraft is also equipped with various instruments, communication equipment, pilot equipment, safety equipment and other equipment according to the needs of aircraft operation and mission execution.
manufacturing process
Aircraft airframe manufacturing should go through the processes of process preparation, process equipment manufacturing, blank preparation, parts processing, assembly and testing. In aircraft manufacturing, matching technology (such as molding line and template working method) and a large number of process equipment (such as various fixtures, molds and frames) are used to ensure that the manufactured aircraft has an accurate shape. Process preparation includes the determination of coordination methods and routes in manufacturing and the design of process equipment.
