    Abstract: In a fuel control system for turbine engines, it is beneficial to provide a minimum fuel signal which prevents the fuel demand of the turbine engine from being decreased below a lower limit which can cause flameout or extinction. The fuel control system of the present invention provides an electronic circuit that includes a portion which dynamically determines the minimum fuel demand of the turbine engine during operation. A circuit is provided to compare the power output of the turbine engine to a predetermined threshold magnitude. The no-load or low-load minimum fuel demand level is continually monitored until the power output of the turbine engine exceeds the predetermined threshold magnitude at which time the stored value of fuel demand is inhibited from being subsequently changed. During later operation of the turbine engine, the stored value of minimum fuel demand is provided to a most fuel bus to operate as a minimum limit of fuel demand for the turbine engine. A temperature compensation device adjusts the minimum fuel demand in response to temperature changes that can occur after the minimum fuel demand is stored.

    Abstract: Pushbutton controls are provided for the power management of a turbine powered aircraft; and these pushbuttons may be mounted on the aircraft pilot's control handwheel. The turbine engine has a maximum rated permissible rotational speed which initially increases with increasing air temperature and with increasing altitude or reduced pressure; and has an absolute maximum limitation, with this maximum permissible rotational speed decreasing at increasing temperatures starting at about 10 or 15 degrees below zero, centigrade; and these limitations are reduced when supplemental equipment such as de-icing equipment is turned on. In accordance with the present invention, a series of "maps", or rotational speed control characteristics reflecting the factors mentioned above, are provided, and the pushbutton controls select among these characteristics, with the "take-off" power button permitting the highest maximum speeds, etc. In addition, automatic timing to reduce the maximum power levels, such as "Take-Off" power or "Performance Climb" power, is provided, to avoid over-stressing the turbine engines. The system may include additional arrangements for limiting the maximum allowable rotational speed of the turbine engine to a speed below that indicated by any of the "maps", when certain pushbuttons such as the "Approach" pushbutton is actuated.

    Abstract: The engine includes a main engine fuel flow, an augmentation fuel flow, and a variable area exhaust nozzle. Primary speed control means is powered by first electrical power supply means. Fan speed is controlled by modulation of main engine fuel flow. Loss of electrical power to the primary speed control means during augmented operation results in a reversion from fan speed control to core engine speed control while simultaneously reducing the augmentation fuel flow toward a minimum level and closing the variable area exhaust nozzle. Backup speed control means is coupled to the primary speed control means for limiting fan overspeed in augmented operation during loss of electrical power to the primary speed control means. The backup speed control means is powered by second electrical power supply means which is independent of the first power supply means. For example, in one embodiment involving aircraft application, the first electrical power supply means comprises an engine-driven alternator and the second electrical power supply means comprises an aircraft positioned power supply. The primary and backup speed control means may be coupled to separate windings of a single torque motor.

    Abstract: For a failure of a sensor utilized in the controls for a gas turbine engine, calculations from other parameters based on the thermodynamics of the cycle serve to simulate the value otherwise manifested by the failed sensor. In this instance, the ratio of burner pressure to engine inlet total pressure generated as a function of corrected rotor speed multiplied by a calculated engine total pressure from aircraft altitude and Mach No. simulates burner pressure utilized in the main fuel control for continuing automatic engine operation.
