摘要： An active control system for use in gas turbine engines synchronizes exhaust nozzle area and burner fuel flow together with pas path variable engine parameters, such as fan variable vane and high compressor variable vane positions. As a result, extremely fast thrust transients are possible with optimized compression system stability, since fan and compressor rotor speeds are held high, allowing total engine power to be controlled by air flow and fuel flows directly.

摘要： The time responsiveness and engine stability for an acceleration and deceleration engine transient is enhanced by a control mechanism that synchronously adjusts fuel flow and high pressure compressor vane position as a function of corrected low pressure compressor speed in a twin spool axial flow turbine power plant. The acceleration and deceleration mode is targeted by power lever position and the target is attained by adjusting the vane position at a constant high pressure compressor speed and returned to a fuel efficient and engine stable steady state operating line by concomittantly adjusting fuel flow and vane position.

摘要： In a gas turbine power plant system having an engine of the variable geometry type, the variable geometry is controlled in response to an input demand speed signal rather than a signal representing actual engine speed. The geometry which may be varied may take many forms depending on engine design, including variable compressor guide vanes, variable turbine nozzle area or variable engine exhaust nozzle area.

摘要： Single shaft, air breathing auxiliary power units having a single stage centrifugal load compressor driven by a gas turbine engine. The latter has a single stage centrifugal compressor and a single stage radial inflow turbine mounted in back-to-back relationship on the same shaft as the load compressor. Control systems for these auxiliary power units feature turbine exhaust gas temperature and turbine speed responsive fuel flow control; a bypass valve control which causes air to be dumped overboard when the pneumatic load demand drops to prevent load compressor surge; and an inlet guide vane control.

摘要： The present invention is particularly concerned with the supply of fuel to fuel servos of gas turbine engines. A check valve (62) is positioned in a return pipe (40, 24, 22, 26) from a fuel spill valve (12) to the upstream low pressure side of a high pressure pump (10). An aperture (32) in a piston (30) of the check valve (62) produces a predetermined pressure drop across the check valve (62) when the flow of excess fuel reaches a predetermined value. A fuel servo shut off valve (64) is positioned in a pipe (42, 58) connecting a fuel flow regulator (14) to a fuel servo (80). A piston (46) of the fuel servo shut off valve (64) initially closes a chamber (56) to prevent fuel being supplied to the fuel servo (80), from the fuel flow regulator (14). The piston (46) of the fuel servo shut off valve (64) is moved against a spring (48) when the predetermined pressure drop is formed across the check valve (62) to allow fuel to be supplied from the fuel flow regulator (14) to the fuel servo (80) via chamber (56).This arrangement allows the use of a smaller pump and reduces recirculation and temperature rises in the fuel at ground idle.

摘要： A fuel and burner variable geometry (BVG) control for a gas turbine engine. Fuel is controlled in response to the product of desired overall fuel-air ratio and a value of air flow derived from gas generator turbine speed. The desired fuel-air ratio is controlled by a speed governor, and by acceleration and deceleration limits varied as a function of measured burner inlet temperature. A compensated turbine inlet temperature (TIT) signal is derived from measurement of actual turbine inlet temperature and acceleration or deceleration compensation based upon rate of change of the desired fuel-air ratio. The difference between the compensated TIT and the burner inlet temperature (BIT) is the burner temperature rise.The setting of air flow control devices in the combustion apparatus (BVG) determines the ratio of primary to total air. The desired ratio to control BVG is computed by dividing burner temperature rise by flame temperature rise. Flame temperature rise is the difference between the desired flame temperature and the measured BIT. The desired flame temperature is scheduled as a function of BIT and BVG. The ratio of primary to total air may be limited temporarily during starting of the engine.

摘要： A control for a variable pitch fan propulsor driven by a turbine type of power plant which fan is mounted in an engine bypass duct having a variable exit nozzle. The control serves to coordinate the control of fuel flow to the engine, the area of the fan exit nozzle, and the pitch of the fan blades by biasing the power lever position signal with Flight Mach No. An additional feature is the inclusion of fan surge control derived from signals of flight Mach No. and corrected free turbine speed.

摘要： One regulation loop controls the fuel supply of a gas turbine and another regulation loop controls the setting of the variable gate mechanism between the compressor turbine and the drive turbine. The second of these loops, unlike the first, has both differentiating and integrating elements. Upon depression of the gas pedal to produce acceleration, the rate of change of the lag between the actual engine speed and the desired engine speed (in particular, compressor turbine speed) is formed as a signal by a differentiator, the rectified output of which is provided as a signal additive to the operating temperature regulation signal so as quickly to provide a short period shift of the regulating gate position to prevent excessive rise of the operating temperature. A provision is also made in the second regulating loop for raising the operating temperature for an amount that is safe for a short period during actuation of a kickdown contact when the gas pedal is fully depressed. The various values for modifying the operation of the regulation loops are introduced in multiple input circuits responsive to a minimum or a maximum input signal, as the case may be, and function generators are used to synthesize modifications of signals from direct measurements and also to synthesize the desired operating temperature in terms of gas turbine speed and ambient temperature.
