Rotary engine (disambiguation)

A rotary engine is a type of internal combustion piston engine used in some early aircraft, motorcycles, and cars. Virtually the whole engine rotates about a fixed crankshaft.

Rotary engine may also refer to:

• Pistonless rotary engine - pistonless internal combustion engines, e.g. the Wankel engine used in some NSU and Mazda cars.
• Turbine - a rotary engine that extracts energy from a fluid flow
• Windmill - a rotary engine that extracts energy from wind
• Waterwheel - a rotary engine that extracts energy from water

For internal combustion piston engines with a fixed engine block of radially-mounted cylinders driving a rotating crankshaft, see radial engine.
