  • Publication number: 20200198764
    Abstract: A propeller pitch control system for a turboprop engine of an aircraft includes an engine control unit and a pitch control unit. The engine control unit is operable to determine a phase of flight of the aircraft and is configured to supply control commands. The pitch control unit is coupled to receive the control commands from the engine control unit and includes a housing, a beta piston, a position sensor, a beta tube, and an electrohydraulic valve. The engine control unit only commands the electrohydraulic valve to move the beta piston from the fully retracted position when the engine control unit determines the aircraft is conducting pre-takeoff roll taxiing operations or is conducting post landing touchdown operations.

  • Publication number: 20200198765
    Abstract: A propeller oil control system for a turboprop engine of an aircraft includes an engine control unit and a propeller oil controller. The engine control unit is operable to determine a flight phase of the aircraft and is configured to supply control commands. The propeller oil controller is coupled to receive a supply of oil and to discharge the oil at a discharge oil pressure. The propeller oil controller includes an electrohydraulic servo valve that receives the control commands moves to a plurality of positions between a first position and a mid-position, and a plurality of positions between the mid-position and a second position. The engine control unit only commands the electrohydraulic servo valve to move out of the first position when the engine control unit determines the aircraft is conducting a take-off roll or the aircraft is in flight.

  • Patent number: 7966995
    Abstract: A system and method provide dual level pressurization control of a fuel supply system based on whether fuel is being supplied to one or more secondary fuel loads. Fuel pump discharge backpressure is maintained above either a first minimum pressure value or a lower second minimum pressure value by determining whether fuel is being supplied to one or more secondary fuel loads. The fuel pump discharge pressure is maintained above the first minimum pressure value if it is determined that fuel is being supplied to the one or more secondary loads. The fuel pump discharge backpressure is maintained above the lower second minimum pressure value if it is determined that fuel is not being supplied to the one or more secondary loads.

  • Patent number: 7841841
    Abstract: A flow prioritizing system includes a regulating valve and a flow prioritizing valve. The regulating valve receives a first portion of the fluid supplied from a fuel supply pump, and is responsive to a control pressure to selectively allow or prohibit flow to secondary loads. The flow prioritizing control valve is responsive to fluid pressure representative of delivery pump discharge pressure to control the control pressure to which the regulating valve is responsive.

  • Patent number: 7836676
    Abstract: A system allows a user to manually manipulate fuel flow to a gas turbine engine during a loss of power to the fuel supply system fuel metering unit. The fuel metering unit includes a fuel metering valve, a metering valve actuator, a fail-fixed valve, a flow increase valve, and a flow decrease valve. The fuel metering unit is configured such that, upon electrical power interruption to the metering valve actuator, the fail-fixed valve shifts and provides a hydraulic lock on the fuel metering valve, to thereby maintain its position. The flow increase and flow decrease valves are powered from a power source that is independent of that used to power the fuel metering unit and, when appropriately energized will allow movement of the fuel metering valve.

  • Patent number: 7565793
    Abstract: A fuel control system (10) for a gas turbine engine includes a main fuel inlet line (18), an auxiliary fuel inlet line (20) and an engine fuel outlet line (16). A first flow path extends from the main fuel inlet line (18) to the engine fuel outlet line (16) and a second flow path extends from the auxiliary fuel inlet line (20) to the engine fuel outlet line (16). A check valve (22) in the first flow path allows fuel flow through the first flow path in a direction from the main fuel inlet line (18) to the engine fuel outlet line (16) and substantially prevents fuel flow through the first flow path in a direction from the engine fuel outlet line (16) to the main fuel inlet line (18). The check valve (22) is shiftable between a first position connecting the auxiliary fuel inlet (20) to the engine fuel outlet (16) and a second position blocking the second flow path. Also a method of controlling fuel flow in a fuel control system of a gas turbine engine.

  • Patent number: 7484522
    Abstract: The present invention provides a relatively simple way to automatically turn on and off the fuel to a starter/generator cooling system during engine start. The present invention takes advantage of a fuel pressure rise provided by an engine fuel boost pump during the period from engine start to engine idle conditions. This pressure rise is used to stroke a shutoff valve in a fuel return to tank valve (FRTTV), which shuts off the starter generator cooling fuel flow. This shutoff occurs automatically with no other external input from, for example, an engine controller. A check valve is also included that prevents back flow through the FRTTV in the event of an engine start with no aircraft pumps running.

  • Patent number: 7252068
    Abstract: The present invention discloses a relatively simple system and method to reduce fuel system pumping by automatically turning on and off servo flow to various non-needed devices or “start lockout” servos during engine start. The invention takes advantage of a fuel pressure rise provided by the fuel pump during the period from engine start until the pump speed is greater than windmill. This pressure rise is used to move a pressure activated piston in a servo shutoff valve from a normally closed position to an open position, which at higher pressures allow servo flow to the “start lockout” servos through the servo lockout valve. When the pressure is reduce, the piston return to a normally closed position due to a biasing spring closing the servo lockout valve. This opening and closing of the servo lockout valve occurs automatically with no other external input.
