Abstract:
1. A starting and generating apparatus for an engine, comprising: a rotator configured to be used as a generator driven by the engine as well as used as a starter motor for starting the engine; a power transmission mechanism configured to connect the engine with the rotator; a starter drive unit configured to supply an electricity to the rotator in order to drive the rotator as the starter motor when the engine is to be started; a clutch mechanism configured to shut off a transmission of power from the engine to the power transmission mechanism when the engine is to be started; and a clutch control unit configured to bring the clutch mechanism into a connected state when a rotational speed of the rotator has reached a given rotational speed at which the engine can be started, wherein the power transmission mechanism includes a continuously variable speed traction transmission having an input disk and an input shaft configured to be connected with an output shaft of the engine, the input disk being mounted on the input shaft so as to be movable relative to the input shaft in axial directions, wherein the clutch mechanism includes a clutch actuation unit configured to make the input disk move in the axial directions so as to switch the clutch mechanism between a connect state or a disconnect state, and wherein the engine is an aircraft engine.
