ABSTRACT:
For a failure of a sensor utilized in the controls for a gas turbine engine, calculations from other parameters based on the thermodynamics of the cycle serve to simulate the value otherwise manifested by the failed sensor. In this instance, the ratio of burner pressure to engine inlet total pressure generated as a function of corrected rotor speed multiplied by a calculated engine total pressure from aircraft altitude and Mach No. simulates burner pressure utilized in the main fuel control for continuing automatic engine operation.
