Abstract
A method for operating a hybrid electric propulsion system of an aircraft, the hybrid electric propulsion system comprising a turbomachine, an electric machine coupled to the turbomachine, and a propulsor coupled to the turbomachine, the method comprising: operating the turbomachine to drive the propulsor; receiving data indicative of a failure condition of the hybrid electric propulsion system; and extracting power from the turbomachine using the electric machine to slow down one or more rotating components of the turbomachine in response to receiving the data indicative of the failure condition.

A method for operating a hybrid electric propulsion system of an aircraft, the hybrid electric propulsion system comprising a turbomachine, an electric machine coupled to the turbomachine, and a propulsor coupled to the turbomachine, the method comprising:
- operating the turbomachine to drive the propulsor;
- receiving data indicative of a failure condition of the hybrid electric propulsion system;
- and
- extracting power from the turbomachine using the electric machine to slow down one or more rotating components of the turbomachine in response to receiving the data indicative of the failure condition.
A hybrid electric propulsion system for an aircraft comprising:
- a turbomachine comprising a combustion section;
- a propulsor coupled to the turbomachine;
- an electric machine also coupled to the turbomachine;
- and
- a controller configured to receive data indicative of a failure condition of the hybrid electric propulsion system during operation of the turbomachine and, in response, extract power from the turbomachine using the electric machine.
