The Tupolev Tu-244 was a proposed supersonic transport (SST) aircraft, developed from the Tu-144. It implemented novel features such as cryogenic fuel to enable flight distances of up to 10,000 km (6,214 mi) and would have carried up to 300 passengers. The project was cancelled in 1993. HistoryThe draft work began in 1979, and when the project ended in 1993 substantial progress had already been made during the interpretation. Specifically, the air resistance in the range of Mach 2 was only 50% higher than a conventional passenger airliner traveling at a speed of Mach 0.9. The nearly-circular fuselage (3.9 m width, 4.1 m height) and the wing unit would have consisted to a large extent of titanium-composite materials. The engines were to be higher performance hydrogen-fuelled versions of the Kuznetsov NK-321-Turbofan, used also with the Tu-160. Adjustable air intake ramps from the Tu-160 might have been included. Projected passenger capacity was 311. Fly-by-wire was intended for flight control. Rather than using a tilting nose, video cameras were to provide the crew with the necessary view for landings.
