ABSTRACT:
Foreign object ingestion damage detection and accommodation system for a gas turbine engine system having a gas turbine engine with multiple rotating members, such as a twin spool configuration. System includes speed sensors for sensing the rotational speed of at least two rotating members. Sensors are coupled to a controller which detects damage by comparing the sensed speed of the second rotational member to an expected speed. Expected speed is determined from the sensed speed of the first rotating member using a known characteristic relationship between the the first and second rotating member speeds for the given gas turbine engine design. Thrust loss accommodation is triggered when damage is detected. Accommodation mode provides a synthesized primary thrust control feedback signal in lieu of the sensed signal for a damaged rotational member. Synthesized signal is derived from the sensed speed for the undamaged rotational member.
