Abstract
A rotor bow mitigation system for a gas turbine engine includes a control system in communication with an actuator, the control system actuates a power source to repeatedly actuate the actuator for a duration of time to intermittently rotate a rotary component such as a high spool of the gas turbine engine. A method of rotor bow mitigation for a gas turbine engine includes intermittently actuating an actuator of a rotor bow mitigation system in selective mechanical connection with a gear within an accessory gearbox to intermittently rotate the rotary component of the gas turbine engine to mitigate rotor bow conditions.
