hand-cranked inertia starter

hand-cranked inertia starter

A starter for a large aircraft reciprocating engine. The hand crank drives a flywheel, which spins at a high speed. Once sufficient flywheel inertia is built up, the hand crank is disconnected and the flywheel is coupled to the engine crankshaft to turn the engine to start it. See hand cranking.
