the early 1960s, military proposed to “thoroughly understand the MiG-21, based on self-designed high-altitude high-speed fighter.”
1965 March, Shenyang Aircraft Design Institute proposed to the higher development of the “double” F-8 fighter of the new report, the design principles: outstanding high-altitude high-speed, not to engage in multi-purpose, all-weather as much as possible . Technical indicators for the main battle: service ceiling 20,000 meters or so, the basic range of 1,500 km, a maximum range of portable missiles 2, 105 gun 1, the radar detection range than the MiG-21 aircraft.
1965 September, F-8 aircraft design in full swing. December of that year, by examining the wooden prototype. Early 1966, the design staff to Shenyang Aircraft Factory and technology, skilled workers to carry out on-site design along with a full set of drawings issued at the end.
the Cultural Revolution period, F-8 aircraft development work difficult. Factory production order was severely damaged, but to participate in the development of the workers regardless of personal safety, keep working. To July 1968, the first two F-8 aircraft assembly is completed.
1968 年 9 15, F-8 aircraft, 02 were static destructive testing machine. When loaded into 92% of design load, multiple broken body, test results failed. The face of setbacks, the majority of technical staff did not give up, continue to research, to December 1968, strengthened the structure of the weak parts, verify and clarify the technical issues.
1969 年 7 月 5 morning 9 am, airport, aircraft factory in Shenyang, Huan test pilot for its first test flight, height of 3,000 meters, speed of 500 km, was a complete success.
Since then, the F-8 aircraft in flight Yanliang Institute continue to test as a test pilot from the East Deer. Continued flight, the aircraft suffered a failure of transonic buffeting, a long time can not exceed the speed of sound. Designers repeated research, to take a variety of ways, and finally completely eliminated in 1977, transonic buffeting failure. Then, F-8 aircraft and engine air parking, etc. to solve the major technical problems.
1979 年 12 31, Air Products F-8 shape Committee agreed to aircraft design shape. March 2, 1980, the State Committee for approval of military products stereotypes shape. F-8 aircraft, the captain (with pitot tube) 21.52 m, wingspan of 9.344 m, height 5.4 m, service ceiling 20,500 meters, a combat radius of 800 km, maximum life time of 2:35.
F-8 aircraft from the flight to the design shape, which lasted 10 years, its development process is the “introduction, digestion, re-innovation” process, indicates that China has embarked on the aviation industry from the imitation design their own path.
