摘要： A stall protector system is provided for a gas turbine engine wherein the compressor pressure is measured, differentiated, and compared with a reference indicative of the maximum rate at which the compressor pressure decreases during normal operation. When the actual rate of decrease of compressor pressure exceeds the reference rate, then the signal is integrated and compared with a second reference indicative of the minimum change in compressor pressure before a stall occurs. If the second reference is exceeded, the fuel flow to the combustor is automatically restricted.
