insanity workout 2 sets of 112 plant immediately

1958 年 3 month from the Shenyang Aircraft Factory (112 Factory) made Dongfeng -104 (DF-104)-type light fighter program, the maximum speed of M1.4 or so. 5,6 and July the same year, 112 plants and 410 plants in developing higher-speed fighters, 8 months, the Aviation Industry Authority, technical meetings of the 112 plants proposed catch up with the world advanced level design and planning, decided to The design index increased to M1.8, ceiling 20,000 meters, which DF -107 (DF-107)-type light fighter program, the overall layout of the reference to the U.S. F-8U aircraft, using a variable angle of attack on the wing design, insanity workout 2 sets of 112 plant immediately after approval of their superior trial work in full swing. January 1959, According to the test in the Soviet  north face denali  and the outcome of the consultation issued in January 1959 after drawing trial finished 2-May, 112 plants and on the drawings were modified to form a DF-107A program, in August 1959 after the trial stopped, due to expected use of the In the same year in September, according to plant party committee's decision, but also designed the DF-107Z reconnaissance aircraft, while the test machine as a wind 107A.
