69 years ago today, on September 8, 1956 (August 4, 1956 lunar calendar), China successfully trial-produced a new type of jet aircraft. On September 8, 1956, China successfully trial-produced a new type of jet aircraft. After the founding of New China, the work of copying and producing jet fighters quickly began. In October 1951, the Chinese and Soviet governments officially signed the "Agreement of the Union of Soviet Socialist Republics to Give the People's Republic of China Technical Assistance in Organizing the Repair of Aircraft, Engines and Organizing Aircraft Plants". On April 18 of the same year, the Ministry of Heavy Industry established the Aviation Industry Bureau to be responsible for the maintenance of aircraft. By the end of 1951, the Aviation Industry Bureau had 18 factories under its jurisdiction and nearly 10,000 employees. In December 1951, Premier Zhou personally presided over a meeting to study and decide that the Soviet-made Yak-18 primary trainer and the MiG-15 would be successfully trial-produced within 3 to 5 years. The rear fighter project was changed to trial-produce the more advanced MiG-17 jet fighter. In 1954, China's first batch of aircraft and their engines were successfully trial-produced. Two years later, on September 8, 1956, Shenyang Aircraft Factory successfully produced China's first jet fighter, the J-5, the MiG-17V, and was subsequently approved for mass production. China became one of the few countries in the world at that time capable of mass production of jet aircraft. Developed by Shenfei Industrial Company, the J-5 is a single-seat single-engine high-subsonic jet fighter, mainly used for daytime interception, with certain ground attack capabilities. The J-5 is a copy of the Soviet MiG-17F (MiG-17F) fighter. The MiG-17F first flew in September 51 and began mass production at the end of 52. The test pilot for the first flight was Wu Keming. At that time, the J-5 was called the Type 56, and it was not renamed the J-5 until 1964. The picture shows the first J-5. The numbered paint at that time was different from the current paint. The trial production work began in October 1954. On July 19, 1956, the prototype flew successfully for the first time, and 13 J-5s were assembled with Soviet parts. On July 13, 1956, the first J-5, all assembled with self-made parts, completed the final assembly. By September 15 of that year, four domestic J-5 aircraft had been manufactured. These four aircraft participated in the National Day Ceremony of 1956. By the second half of 1959, production was discontinued, and a total of 767 J-5F aircraft were produced, which effectively supported the construction of the People's Air Force. The J-5 adopts a single-seat, single-engine, nose intake, and swept-back mid-single-wing layout. The swept-back mid-single wing has a sweep angle of 45 °, which is a double-girder structure. There are angle-controlled retreat flaps on the inside of the wing. Aileron deflection angle range is ± 18 °. The landing gear compartment is at the root of the wing, and the main landing gear is closed in the two compartments of the wing. All-metal semi-hard shell construction The fuselage is a streamlined body with a circular section, and the nose is air-fed. The rear of the fuselage is equipped with a maneuverable speed reducer. The vertical tail is divided into upper and lower sections. The lower section is fixed on the load-bearing inclined frame of the rear fuselage, and the upper section is removable. The vertical tail sweep angle is 55 ° 41 ¡ä. The rudder can be turned 25 °. The horizontal tail swept angle is 45 °, and it is installed on the top of the lower section of the vertical tail. The elevator can be turned 32 ° up and 16 ° down. The front three-point landing gear is all single-wheel. The front landing gear is enclosed in the wheel compartment at the lower part of the front fuselage, and the main landing gear is enclosed in the wing. The main landing gear is equipped with buffers, and the front landing gear is equipped with shock absorbers The main wheel tire pressure is 8.34 × 105 Pa (8.5 kg/cm2). The sealed single-person cockpit can throw off the hatch cover in an emergency, and the ejection seat ensures that the pilot can quickly and safely disengage from the aircraft in an emergency. The control system is hard-type control. The aileron adjustment piece and the elevator adjustment piece are electrically controlled. The hydraulic system is used to retract and lower the landing gear, flaps, reducers, adjustable nozzles and control the aileron. The air-conditioning system is used for braking, sealing the cockpit, emergency retractable landing gear and emergency braking, etc. A turbojet-5 centrifugal afterburner turbojet engine is used, with a static thrust of 2,600 kg and an afterburner thrust of 3,380 kg. The engine is a copy of the VK-1F engine of the Soviet Krimov Design Bureau, which is the engine of the MiG-17. After the establishment of the Aviation Industry Bureau in 1951, it began to organize engine production and learn the Soviet Union's new jet engine production process materials. With the assistance of the Soviet Union, the patent manufacturing right of VK-1F was introduced. In June 1956, a team including Wu Daguan, a well-known engine designer in our country, successfully copied the turbojet-5 at Shenyang Aero Engine Factory (now "Shenyang Liming Machinery Company"). In 1964, the production task was transferred to Xi'an Hongqi Machinery Factory, and the production was finalized and 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 2160 kg. The fuel consumption rate in different states ranges from 2 kg/kg/hour to 1.05 kg/hour. The fuel inside the aircraft is 1170 kg, and two 400-liter auxiliary fuel tanks are mounted externally. The onboard equipment includes ultrashort wave command radio, radio compass, radio altimeter, beacon receiver, identification of friend or foe, tail guard, rangefinder, etc. The wings are swept-back medium single wings, and the deflection angle of the ailerons is ± 18 degrees. There are two 23-1 23mm cannons on the lower left side of the nose, and a 31-type 37mm cannon on on the lower right side of the nose. The loading capacity is 200 rounds. The 23-1 cannon has an initial speed of 680 meters per second and a rate of fire of 800 rounds per minute. The types of ammunition include Hang23-1 fire-killing, Hang23-1 fire-killing tracer, Hang23-1 burn-through, and Hang23-1 training self- The 37-1 type has an initial speed of 690 meters per second and a firing rate of 400 rounds per minute. It was developed in 1954. At the beginning, due to the backward performance of the gun and the existence of successor models in the Soviet Union, only a small amount of production was planned to avoid waste. Later, due to the increase in demand for the J-5, production was finally discontinued in 1959 after 236 bombs were produced. Two bombs of 100-250 kilograms can be hung under the wing. The J-5 has made many achievements. It shot down two F-84Gs and six F-86Fs from July to October 1958, and countless other battles. Interestingly, in April 1956 during the Vietnam War, four F-4s invaded our airspace on Hainan Island. During the interception period of our J-5, the F-4 hastily launched the AIM-7 "Sparrow" missile. Unexpectedly, the J-5 escaped with a small turning radius, and the missing AIM-7 flew to a distant F-4 and shot it down. The J-5 pioneered the jet fighter for our army and laid the foundation for our army to control jet fighters. At present, all J-5s have been withdrawn from active service. In September 1958, our J-5 formation encountered 24 F-86 formations of the Taiwan Air Force over Wenzhou, Zhejiang. Air Force pilot Wang Zizhong was besieged by 12 of the F-86s because he fell behind. After Wang Zizhong shot down two enemy F-86s alone, he was shot down by the AIM-9 "Diamondback" missile carried by the F-86. This is the world's first air-to-air missile in actual combat. But one of the AIM-9s launched by the F-86 that day did not explode, and was found by our soldiers after falling. The 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. Our country's imported imitation is the PL-2 air-to-air missile. However, in the historical records of the National Revolutionary Army, after successfully using the AIM-9 to shoot down the PLA fighter jet, all the pilots participating in the war took a group photo without any casualties. Which is true or false remains to be determined.
