Beschreibung
Zusammenfassung:	A bowed rotor start mitigation system (200) for a gas turbine engine is provided. The bowed rotor start mitigation system (200) includes a controller (102) operable to receive a vibration input indicative of an actual vibration level of the gas turbine engine and a speed input indicative of a rotor speed of the gas turbine engine. The controller (102) generates a bowed rotor start mitigation request based on comparing the actual vibration level to a modelled vibration level at the rotor speed. A corresponding method of bowed motor start mitigation as well as a gas turbine engine system having is also provided.
