Armstrong Siddeley Swiss-Mamba SM-1


The full scaled F+W N-20 aircraft was estimated to have a maximum speed of 1,095 km (680 mph), but the initial converted Mamba, the SM-1, which was test-flown under a de Havilland Mosquito in 1948 and was the first turbofan to fly, did not generate adequate thrust. Considerable further work was required for the definitive two-shaft SM-5 engine, which was meant to generate 14.7 kN (3,300 lbf) thrust. The prototype N-20 was completed in 1952 and, fitted with four SM-1 engines, flew briefly during a taxi test on 8 April 1952, but the development of the engine and the N-20 aircraft was cancelled soon afterwards.
