Korolyov RP-318


The RP-318 or RP-318-1 was USSR's first rocket-powered aircraft or Rocket Glider which "RP" stands for in Russian language. Beginning in early 1936 it was first known as RP-218-1 or "Objekt 218" before it was renamed to RP-318-1 in 1938 due to inner reforms of the :ru:Реактивный институт|Rocket Science And Research Institute.
Built in 1936 by Sergei Korolev as an adaptation of his SK-9 glider, the RP-318 was originally designed as a flying laboratory to test rocket engines and :ru:ОРМ-65|ORM-65 designed by Valentin Glushko was the one selected to be used. In 1938, when both Korolev and Glushko were arrested in suspicion of Anti-Soviet activity, development of the RP-318-1 was continued by Alexei Scherbakov and Arvid Pallo, culminating in the first powered flight on Feb. 28, 1940. Test pilot V. P. Fedorov was towed to 2,600 m and cast off at 80 km/h before firing the rocket engine and accelerating the aircraft to 140 km/h and an altitude of 2,900 m. In all, the RP-318 flew nine times before World War II ended its development.
