Claim 11:
12. A turbine engine comprising:
a rotor assembly;
a starter motor coupled to the rotor assembly; and
a control system configured to perform a plurality of motoring cycles configured to mitigate thermal rotor bow in the rotor assembly, respective ones of the plurality of motoring cycles comprising:
receiving feedback on a temperature within the turbine engine in a post-shutdown state; and
during the post-shutdown state, initiating actuation of the starter motor when the temperature is greater than a predetermined threshold;
operating the starter motor for a motoring time to exhaust some residual heat from the turbine engine; and
shutting down the starter motor after the motoring time.
