SYSTEM AND METHOD FOR ROTOR BOW MITIGATION

A system and method (300) for rotor bow mitigation for a gas turbine engine (10) are provided. An elapsed time since a shutdown of the engine (10) and an idle operation time of the engine (10) prior to the shutdown are determined. A rotor bow mitigation period is determined based on the elapsed time...

Beschreibung
Zusammenfassung:	A system and method (300) for rotor bow mitigation for a gas turbine engine (10) are provided. An elapsed time since a shutdown of the engine (10) and an idle operation time of the engine (10) prior to the shutdown are determined. A rotor bow mitigation period is determined based on the elapsed time and the idle operation time and, prior to initiating a start sequence of the engine (10), the engine (10) is motored for a duration of the rotor bow mitigation period.
