Gas Turbine Engine Fuel Control System Abstract of Disclosure An improved fuel control system for a turboshaft gas turbine engine wherein fuel is metered in proportion to the magnitude of a con- trol pressure and a governor operates in a first mode to regulate compressor discharge pressure down to the control pressure and in a second mode causes the control pressure to increase toward compressor discharge pressure at a relatively rapid rate, the improvement residing in the provision of a valve and an accumulator which operate during the second governor mode to retard the rate of increase of the control pressure toward compressor discharge pressure so that compressor instability is avoided even if the engine is accelerated before internal temperature stability is achieved.
