<P>PROBLEM TO BE SOLVED: To continue suitable fuel flow rate control even when abnormality occurs in a sensor for detecting an outlet pressure of a compressor. Ž<P>SOLUTION: The control device of a gas turbine engine for making air compressed by the compressor flow into a combustor and rotating a turbine by combustion gas in the combustor is provided with an inlet temperature acquiring means for acquiring an inlet temperature of the compressor; an inlet pressure acquiring means for acquiring an inlet pressure of the compressor; an outlet temperature acquiring means for acquiring an outlet temperature of the compressor; an efficiency acquiring means for acquiring efficiency of the compressor; and an outlet pressure deriving means for deriving the outlet pressure of the compressor based on the inlet temperature, the inlet pressure, the outlet temperature and the efficiency of the compressor. Thus, the control device side functions as the alternative means even when abnormality or failure occurs in the sensor for detecting the outlet pressure of the compressor, and suitable fuel flow rate control can be continued.
