Abstract
An aircraft propulsion system includes a gas turbine engine; a generator; a storage battery; a motor which drives a rotor, using at least one of the electric power which is output from the generator and the electric power which is output from the storage battery; a detection unit which detects the number of revolutions of the engine shaft; an engine control unit which controls at least a fuel flow rate of the gas turbine engine; and a generator control unit which controls the operation of the generator. When the number of revolutions satisfies a predetermined condition, at least the generator control unit executes a control for reducing a sudden change in the number of revolutions.
Claims9
An aircraft propulsion system comprising:
- a gas turbine engine mounted on an aircraft;
- a generator which is coupled to an engine shaft of the gas turbine engine and generates electricity using rotation of the engine shaft;
- a storage battery which stores an electric power generated by the generator;
- a motor which drives a rotor, using at least one of the electric power which is output from the generator and the electric power which is output from the storage battery;
- a detection unit which detects the number of revolutions of the engine shaft;
- an engine controller which controls at least a fuel flow rate of the gas turbine engine;
- and
- a generator controller which controls the operation of the generator,
- wherein when the number of revolutions satisfies a predetermined condition, at least the generator controller executes a control for reducing a sudden change in the number of revolutions.
