Abstract: 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.

Abstract: A pair of storage condensers having charging and discharge circuits, and a change-over circuit therebetween, are interconnected under control of a monostable multivibrator so that, when the monostable multivibrator is triggered into unstable state by input pulses, the trailing edge of the flanks of the pulses therefrom are connected to the charging circuit for one of the condensers to charge the condenser; and, connected to the discharge circuit to activate the discharge circuit and permit discharge of the condenser during the reset time of the monostable multivibrator and, additionally, to the change-over circuit to selectively block the change-over circuit. To provide good linearity, a function generator, preferably a dioderesistance network having an approximately parabolic or hyperbolic transfer function interconnects the storage condenser and the discharge circuit therefor. The monostable multivibrator is so connected that an output transistor thereof simultaneously forms part of the discharge circuit, to reduce the number of required components.

Abstract: Arrangement for controlling fuel injection. Transducers generate first and second signals indicative of first and second engine operating conditions. Fuel-quantity selector generates electrical quantity signal indicative of the quantity of fuel to be injected per combustion cycle as a predetermined function of said first and second signals. Timer generates electrical timing signal indicative of time of commencement of fuel injection with respect to the combustion cycle as a predetermined function of said first and second electrical signals. Fuel-injection means commences fuel injection at a time with respect to the combustion cycle indicated by said timing signal, and at such time injects an amount of fuel indicated by said quantity signal.
