Sukhoi Su-1 or I-330 ( _ru. Сухой Су-1) was a prototype Soviet high-altitude fighter aircraft built at the beginning of World War II. Su-3 (I-360) was an improved version of the original design.

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.cite book|author=Shavrov V.B.|year=1994|title=Istoriia konstruktskii samoletov v SSSR, 1938-1950 gg. (3 izd.)|publisher=Mashinostroenie|id=ISBN 5217004770] 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). However, the turbochargers proved unreliable and without them the aircraft was inferior to the Yakovlev Yak-1.cite web|url=http://www.sukhoi.org/eng/planes/museum/su1_3/|title=Sukhoi Su-1, 3|work=Sukhoi Company Museum|accessdate=2007-01-14]

u-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.
