Abstract
An example system includes an electrical machine electrically configured to generate electrical energy used by one or more components of a gas-turbine engine; an energy storage system; and a controller electrically connected to the energy storage system and configured to receive electrical energy from the energy storage system, wherein, in response to the gas-turbine engine being shut off, the controller is configured to cause the electrical machine to rotate a rotor of the gas-turbine engine using the energy received from the energy storage system.
Claims14
A system comprising:
- an electrical machine electrically configured to generate electrical energy used by one or more components of a gas-turbine engine;
- an energy storage system;
- and
- a controller electrically connected to the energy storage system and configured to receive electrical energy from the energy storage system,
- wherein, in response to the gas-turbine engine being shut off, the controller is configured to cause the electrical machine to rotate a rotor of the gas-turbine engine at a speed of less than 100 revolutions per minute using the energy received from the energy storage system.
