Abstract: A gas turbine power plant includes an electric starter for cranking the engine and an electrical control system, both energized from a storage battery. The control system regulates the operation of the engine and includes a fuel valve solenoid and an atomizing air valve solenoid which are electrically energized. When the engine is started, these devices are energized along with the starter. Because of the heavy current required to operate the starter, the other electromagnetic devices are energized slightly before the starter to allow them to pull in while battery voltage is still at a normal level. The control system is energized by a first relay and amplifier or driver circuit and the starter by a second relay and amplifier or driver circuit. The starter amplifier circuit includes a capacitor which delays its operation for approximately 1/20 second after that of the other amplifier.

Abstract: An electrical fuel control system for a gas turbine engine balances a turbine inlet temperature signal against an allowable turbine inlet temperature signal as means for limiting fuel flow to the engine during acceleration. The turbine temperature signal is generated by a thermocouple which has time lag. This signal is compensated for the time lag and for other parameters to improve engine response by a compensating circuit including an operational amplifier. The amplifier has an integrating feedback to compensate for thermocouple lag and it has a differentiating input of a fuel flow signal to provide damping. It has also a feedback of engine acceleration which reduces the temperature compensation to allow for increased fuel flow in anticipation of increased airflow resulting from the acceleration.
