Abstract: A system includes an actuation pump sub-system (APS). A fuel oil cooler (FOC) is included in a first branch of a supply line. The FOC is in fluid communication to receive flow from a second outlet of the APS. The APS includes a bypass valve (BPV) in a second branch of the supply line, in parallel with the FOC and in fluid communication to allow flow from the third outlet into the supply line bypassing the FOC. A combined main and augmentor pump sub-system (CMAPS) has a main inlet connected in fluid communication with the supply line downstream of the BPV and FOC, a gas generator (GG) outlet for supplying fuel to a downstream gas generator, and an augmentor outlet for supplying fuel to a downstream augmentor.

Abstract: A system includes a main supply line and a thermal recirculation pump in fluid communication with the main supply line for supplying the thermal recirculation pump. The thermal recirculation pump is connected in fluid communication with a thermal recirculation line for providing fluid at an elevated pressure to the thermal recirculation line relative to the main supply line. A thermal recirculation control is connected in fluid communication to be supplied from the thermal recirculation line. A cooler system of one or more coolers is connected in fluid communication with a cooler supply line of the thermal recirculation control.

Abstract: The system includes a main supply line. A variable displacement pump (VDP) is in fluid communication with an inlet line and with an outlet line. An actuator is operatively connected for direct control of the variable displacement mechanism. A pressure sensor is operatively connected to the outlet line to generate feedback indicative of pressure in the outlet line. A controller is operatively connected to receive the feedback from the pressure sensor, and operatively connected to the actuator to control the variable displacement mechanism based on the feedback. An actuation system is in fluid communication to be supplied with fluid from the outlet line for use in hydraulic actuation. The actuation system includes an actuation return line connecting the hydraulic actuation system in fluid communication to return fluid to the main supply line.

Abstract: A system includes a variable displacement pump (VDP) with a pump inlet and a pump outlet. The VDP is configured to receive a flow at the pump inlet at a first pressure and to outlet a flow from the pump outlet at a second pressure elevated relative to the first pressure. A second pump is in fluid communication to receive flow at the pump inlet at the first pressure and to outlet flow from an auxiliary outlet. A backup selector is in fluid communication with the pump outlet and with the auxiliary outlet. The backup selector is configured to operate in a normal mode to supply the pump outlet from the VDP and to supply the auxiliary outlet from the second pump. The backup selector is configured to switch to a backup mode to supply the pump outlet from the second pump upon failure of the VDP.

Abstract: A system includes a variable displacement pump (VDP) with a pump inlet and a pump outlet. The VDP is configured to receive a flow at the pump inlet at a first pressure and to outlet a flow from the pump outlet at a second pressure elevated relative to the first pressure. The VDP includes a variable displacement mechanism configured to vary the second pressure. A controller is operatively connected to a pressure sensor and to the variable displacement mechanism for control of the VDP. An output splitter is configured to split flow from the pump outlet to a first outlet branch and to a second outlet branch for supplying two different systems each having a different pressure schedule. The output splitter is operatively connected to the controller, which is configured to control the output splitter to regulate pressure in both of the first and second outlet branches.

Abstract: A fuel supply system includes a pump to be connected to a fuel tank. A metering valve is downstream of the pump. A control is programmed to control at least one of the pump and metering valve. The control is operable to take in a flow demand signal and a fuel pressure signal from a controller associated with a gas turbine engine. The flow demand signal is indicative of a desired flow volume and the fuel pressure signal is indicative of a desired fuel pressure. Operation conditions are identified for the at least one of said pump and the metering valve. A gas turbine engine and fuel supply system is also disclosed.

Abstract: A pump system for a gas turbine engine including a first pump connected to a fluid flow demand line for delivering fluid to a fluid flow demand and a second pump connected, in parallel to the first pump, to the fluid flow demand line and supplementing fluid to the actuation or burner system based on the fluid flow demand. A pressure regulating valve (PRV) is fluidly connected to the flow demand line for bypassing flow to a pump inlet pressure of the first pump and second pump, and controlling a modulated pressure flow signal to a bypass valve, wherein the bypass valve is in fluid communication with the second pump and the PRV for receiving modulated pressure from the PRV and regulating delivery of fluid from the second pump to a bypass flow line.

Abstract: A bearing structure for abutting a pair of gears of a gear pump includes a body including a face on which the gears rotate, an inlet defined in the body, and an outlet defined in the body. The bearing structure includes a sealing portion of the face configured to fluidly seal the inlet from the outlet, the sealing portion being defined as a portion of the face in sealing engagement with the gears at a rotational position of the gears wherein a volume contained by teeth of the gears and the face is constant or about constant as the gears rotate.

Abstract: A system includes a variable displacement pump (VDP) in fluid communication with an inlet line and with an outlet line. The VDP includes a variable displacement mechanism configured to vary pressure to the outlet line. A bypass valve (BPV) includes a BPV inlet in fluid communication with the outlet line, and a BPV outlet in fluid communication with a bypass line that feeds into the inlet line upstream of the VDP. An actuator is operatively connected to control the BPV to vary flow from the BPV inlet to the bypass line. A controller is operatively connected to the actuator to control recirculation flow passed through the BPV based on requested flow from a downstream system supplied by the outlet line and based on a predetermined low threshold of flow through the VDP.
