[edit] Development
The appearance of German turbojet-powered Messerschmitt Me 262 near the end of WWII prompted Soviet Union to develop faster fighter aircraft. Since USSR lacked a production-ready turbojet engine, the efforts were directed toward mixed-power aircraft utilizing a conventional piston engine-driven propeller for the majority of propulsion with a small rocket or jet engine for bursts of speed.[1]
The Su-5 (initially I-107) and the conceptually similar Mikoyan-Gurevich I-250 (N) were designed in 1944. The aircraft first flew on 6 April 1945 and underwent limited flight testing. It was subsequently fitted with a laminar flow wing and attained 793 km/h (428 knots, 493 mph) at 4350 m (14,270 ft) with the thermojet on.[2] On 15 June 1945, the Klimov VK-107A piston engine was damaged beyond repair in flight. Following acquisition of another VK-107A, flight testing continued until 18 October when the engine reached the end of its service life. No further VK-107As could be procured and the project was canceled.[3]
The Su-5 was a conventional monoplane of all-metal construction. The VDRK (Russian: Воздушно-Реактивный Двигатель Компрессорный) thermojet in the rear of the fuselage was powered by a driveshaft from the VK-107 piston engine and could provide an additional 100 km/h (54 knots, 62 mph) of speed for three minutes.[1]
