The Fairey P.16 Prince was a British experimental 1,500 hp (1,118 kW) 16-cylinder H-type 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
The idea came from the desire to deliver high power in a reliable form for naval use. A conventional twin engined aircraft can provide more power than a single, and if an engine fails it can remain airborne on the remaining engine. Unfortunately, a conventional twin could not be designed so that it came within the size limits for aircraft carrier use on the cramped vessels of the era, even with wing folding; by combining two engines into a single engine block, each powering an independently-driven propeller installed fore-and-aft as contra-rotating units, you could get the power and engine-out safety of a twin engine aircraft in the envelope of a single engine aircraft. The added benefits included no dangerous asymmetrical thrust if one unit fails, as happens in a conventional twin that loses an engine, and the drag of both engine nacelles can be eliminated and combined within the cross-section of the fuselage.[3]
