The Polikarpow I-185 ( Russian Поликарпов И-185 ) was a Soviet fighter aircraft from the early 1940s. Although it had good flight performance, it was not mass-produced, probably because its designer Nikolai Polikarpow had fallen out of favor with Josef Stalin .
history
When Stalin personally ordered the development of the Polikarpov I-180 to be stopped, Polikarpov developed the completely redesigned I-185 in just three months. In April 1940 two copies, equipped with an M-90 engine, were completed. Four more copies were equipped with the newly released M-71 and M-82 engines.
The beginning of the Great Patriotic War and the accompanying evacuation of the Polikarpov plant into the hinterland delayed the start of the testing by almost a year.
The I-185M-71 was not able to take off for its maiden flight until February 10, 1942, followed by the I-185M-82 on June 13.
The machines were then tried out with the 728th Fighter Regiment under real combat conditions and proved to be equal, if not superior , to the Lavochkin La-5s deployed at the time .
In 1943 a project called I-187 was still being planned, which was to receive an M-71 drive with adjustable cooling air flaps. It was no longer realized.
