Abstract
A hybrid electric gas turbine engine system includes a first compressor and an auxiliary compressor. The first compressor is configured to output first compressed air. The auxiliary compressor is configured to operate in parallel with the first compressor to output second compressed air. A controller is configured to selectively activate the first compressor or the auxiliary compressor based on an operating condition of the hybrid electric gas turbine engine system.
Claims19
A hybrid electric gas turbine engine system comprising:
- a first compressor configured to output first compressed air;
- an auxiliary compressor configured to operate in parallel with the first compressor to output second compressed air;
- a controller configured to selectively activate the first compressor or the auxiliary compressor based on an operating condition of the hybrid electric gas turbine engine system,
- wherein in response to detecting a non-idle operating condition of the hybrid electric gas turbine engine system the controller deactivates the auxiliary compressor and activates the first compressor to output the first compressed air, and
- wherein in response to detecting an idle operating condition of the hybrid electric gas turbine engine system the controller deactivates the first compressor and activates the auxiliary compressor to output the second compressed air.
A method of controlling an electric gas turbine engine system, the method comprising:
- operating the electric gas turbine engine system according to a current operating condition among a plurality of different available operating conditions;
- selectively controlling, via a controller, a first compressor and an auxiliary compressor configured to operate in parallel with the first compressor, by;
- in response to detecting that the current operating condition is a non-idle operating condition, activating, via the controller, the first compressor to output first compressed air therefrom;
- and
- in response to detecting that the current operating condition is an idle operating condition, activating, via the controller, the auxiliary compressor to output second compressed air therefrom.
