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: A fuel system for a gas turbine engine controls operation of the engine by varying flow of fuel to the engine. When there is a substantial deceleration of the engine, the fuel control shuts off fuel flow. This normally would result in extinction of flame in the combustion apparatus. To avoid the necessity of reigniting the engine, with possible undesirable emissions, a small gas pressure loaded accumulator is connected to the engine fuel line. This charges with fuel when fuel pressure is increased and discharges, to provide a gradually decreasing flow for a short time, when fuel pressure is decreased. The temporary flow from the accumulator is sufficient to maintain combustion during deceleration.

Abstract: A regenerative gas turbine engine has a burner apparatus with a combustion zone and a dilution zone therein and valve means for controlling the amount of air flow into the combustion zone under the control of a deceleration detector including a pressure sealed housing with a movable diaphragm therein forming first and second pressurizable chambers one of which senses discharge pressure of a compressor driven by gas turbine means responsive to vehicle deceleration produced by reduced fuel flow to the burner apparatus. Orifice means in the diaphragm controls pressurization of the chambers by the compressor and spring means are operative to maintain contacts closed during steady state and increasing compressor discharge pressure modes of operation so as to condition the valve means for increased air flow to the combustion zone and the orifice means serve to produce an imbalance of pressure across the diaphragm under vehicle deceleration conditions so as to open the contacts and thereby condition the valve means to reduce air flow to the combustion zone.
