Jakowlew Jak-19 ( Russian Яковлев Як-19 , NATO code name Type 7 ) is the name of a fighter aircraft developed in the late 1940s . It was Yakovlev's first all-metal construction and was built in two copies.
development
While the two previous models Jak-15 and Jak-17 were still based on the piston engine- Jäger Jak-3 , the Jak-19 was completely redesigned.
The drive used was the RD-10F , the first jet engine with an afterburner, developed at the Central Institute for Aircraft Engines (ZIAM) at the end of 1946 . At the beginning of 1947 the first prototype Yak-19-I took off on its maiden flight with Sergei Anochin . The guy was presented to the public at the air parade in Tuschino that same year. On the second Jak-19-II machine , the tailplane was given a slight V position and additional fuel tanks were attached to the wing tips. The flight tests ended in October 1947 and certified the model to be suitable for pilots with medium qualifications . In the end, the series production was abandoned because aircraft with significantly better performance data were already available at that time.
technical description
The Jak-19 was made of all-metal construction with an almost circular fuselage cross-section. The trapezoidal wings had a laminar profile and were not swept. The struts of the main landing gear drove into the wings, the main wheels and the nose wheel into the fuselage. The fuel tanks were arranged in a ring around the central air duct in the middle of the fuselage.
