Abstract
Systems and methods for detecting and accommodating for loss of a torque signal of a gas turbine engine are described herein. An engine deterioration offset may be determined while the torque signal of the engine is available. Then, in the event that the torque signal is lost, a predicted operating offset may be determined. A synthesized torque signal may be generated when the torque signal is lost at least in part from the engine deterioration offset and the predicted operating offset.
Claims20
A method for accommodating loss of a torque signal of a gas turbine engine, comprising:
- determining an engine deterioration offset while the torque signal of the engine is available;
- determining a predicted operating offset when the torque signal is lost;
- and
- generating a synthesized torque signal when the torque signal is lost at least in part from the engine deterioration offset and the predicted operating offset.
A system for accommodate for loss of a torque signal of a gas turbine engine, the system comprising:
- at least one processing unit;
- and
- a non-transitory computer-readable memory having stored thereon program instructions executable by the at least one processing unit for:
- determining an engine deterioration offset while the torque signal of the engine is available;
- determining a predicted operating offset when the torque signal is lost;
- and
- generating a synthesized torque signal when the torque signal is lost at least in part from the engine deterioration offset and the predicted operating offset.
