rotary engine

n.
An engine, such as a turbine, in which power is supplied directly to vanes or other rotary parts.

rotary engine

n
1. (Automotive Engineering) an internal-combustion engine having radial cylinders that rotate about a fixed crankshaft
2. (Automotive Engineering) an engine, such as a turbine or wankel engine, in which power is transmitted directly to rotating components

ro′tary en′gine


n.
1. an engine, as a turbine, in which the impelling fluid produces torque directly rather than by acting upon reciprocating parts.
2. an internal-combustion engine, as the Wankel engine, whose power is developed by a rotor revolving in the combustion chamber.
3. a revolving radial engine.
