[edit] Development
In 1939, Sukhoi was tasked with designing a high-altitude fighter. The resulting Su-1 was a conventional monoplane with a streamlined wooden semi-monocoque fuselage and a low-set all-metal wing made of duralumin. The cockpit was not pressurized. The key feature of the aircraft was a pair of TK-2 turbochargers driven by exhaust gases from the Klimov M-105P engine.[1] The prototype was completed in May 1940. It first flew on 15 June 1940 with A.P. Chernyavsky at the controls and underwent limited flight testing until April 1941, reaching a top speed of 641 km/h (345 knots, 400 mph) at 10000 m (32,810 ft).[1] However, the turbochargers proved unreliable and without them the aircraft was inferior to the Yakovlev Yak-1.[2]
[edit] Su-3
The second Su-1 prototype was built as a Su-3 which differed in having a revised wing with wing area reduced to 17 m² (183 ft²). It was completed in 1941 but did not fly. The project was abandoned due to continuing problems with the TK-2 turbochargers.[1]
