Abstract:
A method for mitigating restart pinch during a hot restart. The method comprises providing a gas turbine engine including a stator and a rotor rotatably situated within the casing of the stator and providing an external heat source capable of selectively supplying auxiliary heat to the casing. The method further comprises operating the gas turbine engine for a first period of time at a steady state condition without supplying the auxiliary heat to the casing and supplying the auxiliary heat to the casing for a second period of time when shutting down the gas turbine after operating at the steady state condition for the first period of time.
