72179 YAKOVLEV YAK-50 AND YAK-52 FLIEGER REVUE AEROBATIC TEAM(2 MODELS)

The Yak-52 was a Soviet, and is now a Russian low-wing training aircraft from the post-war period. The prototype flight took place in 1976. Serial production was carried out in the years 1978-1998, and license production in Romania - is still in progress. The drive is provided by a single motor Vienna M-14P with 360 HP. The length of the machine is 7.75 meters with a wingspan of 9.3 meters. The Yak-52 aircraft was developed at the Yakovlev design bureau as a successor to the very successful Yak-50 aerobatic machine. Compared to its predecessor, the machine has the same engine, but slightly changed aerodynamic properties. It is also clearly heavier and has different sizes. The Yak-52 also features a full metal construction. It is worth adding that despite the changes, the Yak-52 was and is still used successfully as an aerobatic machine! The plane turned out to be a highly successful design and in the 1970s and 1980s it was the basic training and training aircraft of the Soviet aviation. It was used on a large scale in the DOSAAF organization.The Yakovlev Yak-50 (1949) was a Soviet mid-wing prototype fighter from the post-war period. The prototype's flight took place in 1949, but the machine never entered mass production. The drive was provided by a single turbojet engine with a WK-1 centrifugal compressor. The deck armament was to consist of two 23mm NR-23 cannons. The Yakovlev Yak-50 was designed as a new interceptor with a Korshun radar station and the highest possible top speed of 1100 km / h. Trying to achieve these ambitious goals, the Yakovlev design office strived to reduce the weight of the aircraft as much as possible and to refine its aerodynamics as much as possible. Finally, a machine with a high maximum speed was created - in a dive flight exceeding the speed of sound. At the same time, however, the machine was characterized by poor longitudinal stability at a speed of about 1000 km / h, clearly difficult to fire accurately and susceptibility to crosswind when landing. Finally, in 1951, the development of the design was abandoned in favor of the much more successful MiG-17 aircraft.
