After the founding of the People's Republic of China, New China quickly began to imitate the production of jet fighters. On June 5438+095 1 10, the Chinese and Soviet governments formally signed the Agreement between the * * * Union of Soviet Socialist Republics and China on Organizing Aircraft Repair and Engine Repair and Technical Assistance to the People of China by Aircraft Factories. In April 18 of the same year, the Ministry of Heavy Industry established the Aviation Industry Bureau, which was in charge of aircraft maintenance. 195 1 At the end of the year, Aviation Industry Bureau * * * owned 18 factory with nearly 10,000 employees. 195 1 65438+February, Premier Zhou personally presided over the meeting and decided to successfully trial-produce the Soviet-made Jacques-18 primary trainer and MIG-15 in three to five years. The post-fighter project was changed to trial production of more advanced MIG-17 jet fighters. 1954, the first batch of aircraft and their engines in China were successfully trial-produced. Two years later, on September 8th, 1956, Shenyang Aircraft Factory successfully trial-produced China's first jet fighter, namely MiG-17Ф, and was subsequently approved for mass production. China became one of the few countries in the world that could mass-produce jet planes at that time.
Developed by Shen Fei Industrial Company, J-5 is a single-seat high subsonic jet fighter, which is mainly used for daytime interception and has certain ground attack capability. Ф 5 is an imitation of the Soviet MIG-17Ф fighter. MIG-17F 5 1 made its first flight in September and began mass production at the end of 52. The test pilot of the first flight was Wu Keming. At that time, 歼 5 was called Type 56, and it was renamed 歼 5 until 1964. The picture on the left shows the first frame 歼 -5, and the digital painting at that time is different from the current painting. Trial production of/kloc-0 began in June, 1954, and the prototype made its first flight in July19. 13 J-5s were assembled with Soviet-made parts. 1July 3, 956, the final assembly of the first 歼 5 was completed. By September of that year, 15, four domestic J-5 aircraft had been manufactured. These four planes attended the National Day ceremony of 1956. 1959 stopped production in the second half of the year and produced 767 J -5F 767 aircraft, which strongly supported the construction of the People's Air Force.
The J -5 adopts the layout of single seat, single engine, nose intake and swept middle wing. The sweepback angle of the swept middle wing is 45, which is a double-beam structure. There is a retractable flap with controllable angle on the inside of the wing. The aileron deflection angle range is 65438+08. The landing gear compartment is located at the root of the wing, and the main landing gear is installed in two compartments of the wing. The all-metal semi-monocoque structure fuselage is a streamlined fuselage with a circular cross section, and the nose is used for air supply. The rear of the fuselage is equipped with a steerable speed brake. The vertical tail is divided into upper and lower sections, the lower section is fixed on the inclined frame of the rear fuselage, and the upper section is detachable. The sweep angle of the vertical tail is 55 41'. The rudder can be turned by 25. The horizontal tail has a sweepback angle of 45 and is installed at the top of the lower part of the vertical tail. The elevator can rotate 32 up and16 down. The first three-point landing gear was a single wheel. The front landing gear is installed in the wheel well at the lower part of the front fuselage, and the main landing gear is installed in the wing. The main landing gear is equipped with a buffer, and the front landing gear is equipped with a shock absorber and a shimmy damper. The main tire pressure is 8.34× 105 Pa (8.5 kg/cm2). The sealed single cockpit can throw away the hatch cover in an emergency, and the ejection seat can ensure the pilot to get off the plane quickly and safely in an emergency. The control system is hard-controlled. Aileron wings and elevator wings are electric. The hydraulic system is used to retract the landing gear, flaps, speed brake, adjustable nozzles and control ailerons. Air conditioning system is used for braking, sealing cockpit, emergency landing gear retraction and emergency braking.
Using turbojet -5 centrifugal afterburner turbojet engine, the static thrust is 2600 kg, and the afterburner thrust is 3380 kg. This engine is an imitation of VK- 1F engine of kerimov Design Bureau of Soviet Union, and VK- 1F engine is MIG-17 engine. 195 1 After the establishment of Aviation Industry Bureau, it began to organize engine production and learn the new production process data of Soviet jet engines. With the assistance of the Soviet Union, the patent manufacturing right of VK- 1F was introduced. From June 65438 to June 0956, Wu Daguan, a well-known domestic engine designer, and other teams successfully copied the turbojet -5 in Shenyang Aeroengine Factory (now "Shenyang Liming Machinery Company"). 1964 The production task was transferred to Xi 'an Hongqi Machinery Factory, and it was put into mass production in 66 years. The turbojet -5 afterburner thrust is 3380 kg, the maximum thrust is 2700 kg, the rated thrust is 2400 kg, and the cruise thrust is 2 1.60 kg. The fuel consumption in different states ranges from 2kg/kg/ hour to 1.05kg/ hour. The fuel in the engine is 1 170 kg, and two 400-liter auxiliary fuel tanks are externally connected.
Airborne equipment includes ultrashort wave command station, radio compass, radio altimeter, beacon receiver, friend or foe identifier, tail protector, range finder, etc.
The wing is a swept middle wing, and the aileron deflection angle range is 65438 08 degrees. Two 23- 1 type 23mm guns are installed on the lower left side of the nose, and 1 door 3 1 type 37mm guns are installed on the lower right side of the nose. The load is 200 rounds. The muzzle velocity of the 23- 1 machine gun is 680m/s and the firing rate is 800 rounds per minute. The types of bombs are air 23- 1, air 23- 1, air 23- 1, air 23- 1, self-training bombs. The 37- 1 model has an initial velocity of 690 m/s and a firing rate of 400 rounds per minute. Development started at 1954. At the beginning, due to the backward performance of the gun, there were subsequent models in the Soviet Union. In order to avoid waste, only a small amount of production was planned. Later, due to the increasing demand for J-5, 236 doors were finally produced and stopped production in 1959. Two bombs 100-250kg can be hung under the wing.
The famous pilot when New China was founded: Wang Ziwei.
歼 -5 has made many achievements, shooting down two F-84G and six F-86F from July 1958 to October 10. There are countless other examples. Interestingly, 1956 During the Vietnam War in April, four F-4s invaded the airspace of Hainan Island. In the process of intercepting our army 歼 5, the F-4 suddenly launched the AIM-7 Sparrow missile, but 歼 5 escaped because of its small turning radius. The off-target AIM-7 actually flew to the distant F-4 and shot it down.
1958 in September, 24 F-86s of Taiwan Air Force met with our army, and Wang Ziwei, an air force pilot, was besieged by 12 F-86s for falling behind. After Wang shot down two enemy F-86s single-handedly, he was shot down by the AIM-9 rattlesnake missile carried by the F-86. This is the record of the first actual air-to-air missile in the world. However, an AIM-9 launched by the F-86 did not explode that day, and it was discovered by our military and civilians after falling. This AIM-9 was sent to the Soviet Union. On this basis, the Soviet Union successfully developed the K- 13(AA-2) air-to-air missile. China imported an imitation Thunderbolt -2 air-to-air missile.

The main modifications of the J-5 include the J-5 A fighter, which is an improved night fighter based on the J-5 in China. The front fuselage is thick, and there is a shark beak radome at the upper end of the nose, which protrudes 365,438+03 mm from the front edge of the inlet, and a hemispherical antenna cone is installed in the inlet. These two parts are made of nonmetallic materials with less hardness and painted with blue paint. Thanks to the simple RP search and aiming radar, the 歼 5 A has stronger night fighting capability than the prototype. The engine adopts turbojet -5 B with improved performance. However, there is a certain cost to improve the J -5A. For example, the weapon system was changed to three HP-23 23 23mm cannons and 300 rounds of ammunition, which was slightly lower than the basic firepower. Two 250kg bombs can be externally hung. In the battle against the reconnaissance and refitting of the US B- 17G bomber, our military technicians improved the RP radar of the J -5A, changing the downward field of view from 14 to 7 degrees, and keeping the upward field of view unchanged, thus shielding the ground reflection clutter received by the radar when chasing the low-flying B- 17G. On May 29th, 1959, Jiang Zhelun, the captain of the interception brigade of the Air Force 18 Division, successfully shot down B- 17G with this modified fighter.
In addition, a small number of retired J -5 s have been converted into unmanned drones, which may be code-named "Target Five B".
