The Rafaelyants RAF-11 was a Soviet transport aircraft of the late 1930s, designed by Aram Rafaelyants and first flown in 1938.
The RAF-11 was built from 1937 to 1938 and first flown in 1938. It was a twin-engine cantilever monoplane with a semi-monocoque fuselage, powered by two Kossov MG-31 engines. The aircraft was of wooden construction with ply covering at the back of the wings and fabric throughout. The wing was of two-spar construction. The landing gear retracted into the engine nacelles using a hydraulic system and an additional pneumatic system for emergency extension. The aircraft had a capacity of six passengers. The RAF-11 was too heavy and its performance unimpressive.
In 1940, the RAF-11bis first flew, which was a refined version of the RAF-11. It had reduced weight and slightly reduced fuel capacity. The aircraft was fitted with more powerful MG-31F engines. The RAF-11bis had outstanding performance and could be used in both airliner and trainer roles. Series production was to start in 1941 but never commenced due to World War II. Both examples flew during the war.
