The Fairey P.16 Prince was a British experimental 1,500 hp (1,118 kW) class H-16 aircraft engine designed and built by Fairey in the late 1930s. The engine did not go into production.[1]
Design and development
The Prince P.16 was a radical design by Captain A.G. Forsyth who was the Fairey company's chief engine designer. Similar in layout to the Napier Rapier, the cylinders were arranged vertically in two separate blocks, driving contra-rotating propellers via separate shafts and gears. Each bank of cylinders could be shut down in flight to drive only one propeller, an idea that was reused much later in the Armstrong Siddeley Double Mamba turboprop. The engine was test flown in a Fairey Battle.[2]
The idea came from the desire to deliver high power in a reliable form for naval use. A twin engined aircraft could not be designed such that even when "folded" it came within the limits for aircraft carrier use; with two power blocks the failure of an accessory would not lead to failure of the engine as a whole.[3]
