ABSTRACT:
A torque signal synthesis method is provided to accommodate torque measurements for a gas turbine engine. The torque signal is synthesized from gas pressure sensed at an engine station. The synthesized torque signal may include a correction factor which accounts for the deviation of the engine from a nominal characteristic. This correction factor is determined during engine operation and periodically updated to account for changes in the deviation. The synthesized torque signal may further be determined from the corrected speed of a gasifier rotor and power turbine of a free turbine engine configuration.
