摘要： A control system for a two-shaft regenerative gas turbine has a low emission burner with a pedal operated throttle for proportioning the flow of primary and secondary air into a combustion chamber of the low emission burner and includes means for controlling fuel flow to maintain the outlet temperature of the burner in a range of temperatures to cover the power and speed range of the turbine engine. Secondary air is modulated to temper the turbine inlet temperature for a particular power level and speed of operation of the engine. The controller regulates the fuel supply at the burner in accordance with primary air flow by means for sensing the mass air flow to the engine compressor and means for automatically adjusting the fuel flow in correct proportion to the primary air flow to the burner so that the temperature of the primary combustion zone will be held at a desired level without adjusting the burner variable geometry or without sensing primary combustion zone temperature. An improved thermostat multiplier mechanism adjusts a fuel orifice to compensate for inlet air temperature to the burner.

摘要： A hydraulic position servo system drives an output to follow a mechanical input over a normal range. An electrically-operated valve provides for output travel beyond the normal range independently of the mechanical input. The servo system includes a primary control valve moved by the mechanical input and output movements and a slave valve controlled by pressure differential generated by the other valves. The primary control valve embodies a pintle laterally shiftable in a cylinder to differentially throttle two orifices to establish a variable control pressure. The slave valve differentially throttles the inputs to a doubleacting servo cylinder. Reciprocal jet pumps in the connections to the return line from the slave valve act to energize return flow from the servo cylinder in either direction of movement.

摘要： A fuel supply and control system for a gas turbine engine includes a pump, a fuel metering valve, and a cutoff valve connected in series between a source of fuel and the fuel nozzle of the combustion apparatus. The rate of fuel supply responds to a manually operable power level control. The flow area of the metering valve is determined by the product of the power level input and the pressure of air supplied to the combustion apparatus. A by-pass valve controlling the pressure drop across the metering valve responds to this pressure drop and to a bias proportional to ambient temperature so that the metering head is proportional to ambient temperature. The cutoff valve closes when the pressure of the fuel delivered to the fuel nozzle is above that called for by the power control input.
