In the early 1950s, the primary trainer aircraft used by the Air Force was the Soviet Yak-18. At that time, the Nanchang Aircraft Factory was able to independently produce the aircraft in accordance with Soviet drawings. The steel frame of the Yak 18 type of steel frame, the structure of the outer cover was relatively backward, and the airborne power supply was insufficient. Designers such as Xu Shunshou believe that it is no longer necessary to introduce the improved Yak 18A, and it is entirely possible to independently develop a primary trainer based on domestic technical strength.
In July 1957, the Chujiao 6 design was begun, and the prototype flew for the first time in August of the following year. On January 5, 1962, Chujiao-6 completed the design finalization. After the successful test flight of the Chujiao 6 in Nanchang, many people in the aviation industry system and the air force still believed in the Soviet aircraft and advocated the production of the Yak 18A. Until a new leader of the Aviation Industry System took office, he decided to continue to improve the elementary trainer 6.
The body of Chujiao 6 adopts an all-metal thin-skinned shell structure, which is similar to the Yak 18 in appearance. The actual fuselage, wings and front three-point landing gear are all new designs.
A Chinese derivative of the Yak-18, and development of the CJ-5, the CJ-6 is aerobatic, with a fully retracting undercarriage.
A military primary trainer, approximately 2000 were built for the Peoples Liberation Army Air Force from 1962. It has also served with the air forces of Albania, Bangladesh, Cambodia, Tanzania and Zambia.
The improved CJ-6A still being built in the late 1990s in very low volume for the same radial piston-engined primary training role.
Elementary Education 6 also has many shortcomings: the onboard equipment is backward, there is no ejection rescue system, the cockpit is not sealed, the noise is loud, and the operating environment is not good in cold weather. Therefore, the domestic development of a new generation of primary trainers has been brewing since the 1990s. In August 2007, Chujiao 7 was formally established, and the first flight was successful in 2010, and it was publicly unveiled at the Zhuhai Air Show.
In 2015, Hongdu Company officially began to resume primary education 6. It can be seen in the news that there are a large number of newly manufactured Chujia 6 in the Hongdu Aviation Workshop. The production number of the fuselage shows that the output is at least dozens of aircraft. The Air Force has resumed bulk purchase of Chujia 6, and Chujia 7 is completely yellow.
