Chyeranovskii BICh-11

The BICh-11 (a.k.a. RP-1) (Raketnyii Planer – rocket glider) was a twin-engined tailless research aircraft designed and built in the USSR from 1931.

Development
The BICh-11 was the first purpose-designed rocket-powered aircraft in the world. It was planned to power the BICh-11 with two Tsander OR-2 liquid fuelled rocket engines; however it was never flown with the rocket engines as they had not been proven safe for use in crewed aircraft. Flight testing began early in 1932 as a bungee-launched glider with ski undercarriage. Later flight tests used an ABC Scorpion piston engine.

The 50 kg (110 lb) thrust Tsander OR-2 engines were to have been mounted either side of the central nacelle in small over-wing fairings, with large liquid-oxygen and gasoline tanks mounted forward of the engines' combustion chambers. The rocket engines were successfully bench run in 1933, but were never installed in the aircraft.
