Abstract
An auxiliary propulsion apparatus of an air vehicle may include an engine mounted in a fuselage of the air vehicle, a generator configured to be driven using power from the engine, a compressor configured to be driven by the engine or the generator, a battery configured to store electricity generated by the generator, an electricity distributor connected to the generator, the battery and the main propulsion apparatus and configured to distribute electricity generated by the generator to the battery and to a main propulsion apparatus, and at least one nozzle device configured to jet high-pressure gas, supplied from the compressor, to an outside of the fuselage.
Claims5
A method of controlling an auxiliary propulsion apparatus of an air vehicle, the method comprising:
- providing the auxiliary propulsion apparatus including an engine mounted in a fuselage of the air vehicle;
- a generator engaged to the engine and configured to be driven using power from the engine;
- a compressor engaged to the engine and the generator and configured to be driven by the engine or the generator;
- a battery electrically connected to the generator and configured to store electricity generated by the generator;
- an electricity distributor connected to the generator, the battery and a main propulsion apparatus and configured to distribute electricity generated by the generator to the battery and the main propulsion apparatus;
- at least a nozzle apparatus connected to the compressor and configured to jet pressurized gas supplied from the compressor, to an outside of the fuselage;
- a first clutch mounted between the engine and the generator and configured to selectively engage transmission of power from the engine to the generator;
- and a second clutch connected to the first clutch in series to selectively engage transmission of the power from the engine to the compressor via the first clutch,
- engaging, by a controller electrically connected to the second clutch, the second clutch when an abnormal state occurs in the main propulsion apparatus;
- determining, by the controller, whether the engine has failed;
- disengaging, by the controller electrically connected to the first clutch and the generator, the first clutch and driving the generator using power from the battery to drive the compressor, upon determining that the engine has failed;
- and
- controlling, by the controller electrically connected to the nozzle apparatus, the nozzle apparatus to jet the pressurized gas supplied from the compressor, through the nozzle apparatus to supplement a thrust force of the air vehicle.

- a first clutch mounted between the engine and the generator and configured to selectively engage transmission of power from the engine to the generator;
- and a second clutch connected to the first clutch in series to selectively engage transmission of the power from the engine to the compressor via the first clutch, wherein the nozzle apparatus includes a lift-generating nozzle apparatus configured to jet the pressurized gas in a downward direction of the fuselage of the air vehicle;
- and a thrust-generating nozzle apparatus configured to jet the pressurized gas in a rearward direction of the fuselage of the air vehicle,
- engaging, by the controller electrically connected to the second clutch, the second clutch when an abnormal state occurs in the main propulsion apparatus during vertical takeoff and landing of the air vehicle;
- determining, by the controller, whether the engine has failed;
- disengaging, by the controller electrically connected to the first clutch and the generator, the first clutch and driving the generator using power from the battery to drive the compressor, upon determining that the engine has failed;
- and
- controlling, by the controller electrically connected to the lift-generating nozzle apparatus, the lift-generating nozzle apparatus to jet the pressurized gas supplied from the compressor, through the lift-generating nozzle apparatus to assist takeoff and landing of the air vehicle.
