The Mamba was a British turboprop engine produced by Armstrong Siddeley's in the late 1940s and 1950s, producing around 1,500 effective horsepower (1,100 kW).
The Mamba has was a compact engine [1] with a 10-stage axial compressor, 6 combustion chambers and a two-stage power turbine. The epicyclic reduction gearbox was incorporated in the propeller spinner. Engine starting was by cartridge. The internal deisgnation was A.S.M (Armstrong Siddeley Mamba). ASM.3 gave 1,475 ehp and the ASM.6 was rated at 1,770 ehp.
A 500-hour test was undertakenout in 1948[1]. The Mamba has the first turboprop engine to power the Douglas DC-3 Dakota. In 1949, a Dakota testbed was converted to take two Mambas.
The Mamba was developed into the form of the Double Mamba, which was used on the Fairey Gannet anti-submarine aircraft for the Royal Navy. This was essentially two Mambas lying side-by-side and driving a contra-rotating propellers through a common gearbox. A turbojet version of the Mamba was developed as the Armstrong Siddeley Adder, by removing the reduction gearbox.
