Nordholz - Fairey Gannet A.S.4
This is a German Navy Gannet anti-submarine warfare airplane, UA+113, on static display at the Nordholz "Aeronauticum" naval aviation museum.
Quite unique on the Gannet are the two counterrotating props, each powered by it's own turbine engine. The complete power plant was called an Armstrong Siddeley Double Mamba, consisting of two Armstrong Siddeley Mamba driving the counterrotating props through a combining gearbox. The Double Mamba provided 3,145 shp.
The use of coaxial, counterrotating props eliminated the prop torque moment as long as both props received the same amount of power.
And the coaxial arrangement meant that the plane could be flown on one engine (e.g. to save fuel and extend the range) without the adverse effect (yaw moment) that occurs when twins with wing mounted engines are flown as "single".
