Abstract

An operating method is provided during which a command is received to decrease thrust generated by a propulsor rotor (26) from a first thrust level to a second thrust level. The propulsor rotor (26) is operatively coupled to an engine core (14) and an electric machine (66). The engine core (14) includes a flowpath (32), a compressor section (28), a combustor section (29) and a turbine section (30). The engine core (14) is operated in a transient state to decrease total power of the engine core (14) from a first power level to a second power level in response to the command. The electric machine (66) is operated as a generator to reduce power output from the engine core (14) to the propulsor rotor (26) while the engine core (14) is operating in the transient state. A clearance control system (20) for the engine core (14) is operated based on the operation of the electric machine (66).
