ABSTRACT:
A pressure signal synthesis method is provided to accommodate failure of a pressure sensor in a gas turbine engine. The pressure signal is synthesized from the torque produced by the engine, and further determined from the corrected speed of a gasifier rotor and power turbine for a free-turbine engine configuration. The synthesized pressure 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.
