Armstrong Siddeley Double Mamba
- Armstrong Siddeley Double Mamba
The Double Mamba was an Armstrong Siddeley gas turbine turboprop engine design of around 3,000–4,000 hp (2,500–3,000 kW). It was used mostly on the Fairey Gannet anti-submarine aircraft developed for the Fleet Air Arm of the Royal Navy.
The Double Mamba (also known as the Twin Mamba) was a development of the Armstrong Siddeley Mamba with two Mambas driving contra-rotating propellers through a combining gearbox.
Engine starting was by cartridge, however, forced air restart was achieved in flight. One engine could be shut down in flight to conserve fuel.
Variants and applications
The numbering system for these engines reflects the obvious linkage to their Mamba lineage:
AS = Armstrong Siddeley
M = Mamba
D = Double
num = model
The Double Mamba engine was also proposed for the Westland Westminster, a 30-seat helicopter that was later prototyped with another engine.
