SYSTEMS AND METHODS FOR ENGINE WEAR REDUCTION

Abstract: an engine may include a processor communicatively coupled to a pitch actuator configured to affect a pitch of a plurality of variable pitch blades and a secondary thrust effector device. the processor is configured to change the pitch of the plurality of variable pitch blades via the pitch actuator in response to changes in a target engine parameter a normal operating mode, detect a trigger condition for a wear reduction mode, and switch from the normal operating mode to the wear reduction mode, wherein in the wear reduction mode, the pitch of the plurality of variable pitch blades is maintained at a first angle, and the secondary thrust effector device is controlled in response to the changes in the target engine parameter.
