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. An electromechanical actuator (EMA) is operatively connected to actuate the variable displacement mechanism. A flow sensing valve (FSV) connected in the outlet line. The FSV includes a sensor configured to generate sensor data indicative of flow out of the outlet line. A controller is operatively connected to the EMA to control the variable displacement mechanism based on the sensor data to support flow demands from one or more downstream systems.

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 fuel metering system includes a pump with an inlet and an outlet, a first flow path including a first valve fluidically connected to the outlet of the pump, and a second flow path including a second valve fluidically connected to the outlet of the pump, a third valve, and a fourth valve. An electrohydraulic servo valve in a first position hydraulically connects the inlet of the pump to the first, third, and fourth valves to close the first valve, open the third valve, open a first window of the fourth valve, and close a second window of the fourth valve. The electrohydraulic servo valve in a second position hydraulically connects the outlet of the pump to the first, third, and fourth valves to open the first valve, close the third valve, close the first window of the fourth valve, and open the second window of the fourth valve.

Abstract: A system includes an actuation pump sub-system (APS) with an inlet configured to feed fuel from a fuel source into the APS, a first outlet configured for connecting the APS in fluid communication with an actuation system to supply fuel flow for actuation, a second outlet feeding into a supply line, and a third outlet feeding into the supply line. A fuel oil cooler (FOC) is included in a first branch of the supply line. The FOC is in fluid communication to receive flow from the second outlet. 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 main pump and control sub-system has a main inlet connected in fluid communication with the supply line downstream of the BPV and FOC.

Abstract: A journal bearing for a gear driven pump includes a bearing body having a bearing body circular opening that defines a bearing surface along a length of the bearing body and a face plate adjacent to the bearing surface. The bearing surface is configured to carry a gear shaft load through a hydrodynamic fluid film pressure between a load surface of a gear shaft and the bearing surface. The bearing surface is formed from a leaded bronze material and the face plate is formed from a copper-nickel alloy.

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. 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. An electromechanical actuator (EMA) is operatively connected to actuate the variable displacement mechanism. A temperature sensor is operatively connected to the outlet line to generate sensor output indicative of fluid temperature in the outlet line, wherein the temperature sensor is operatively connected to a controller for active control of the EMA and/or of the actuator based on temperature in the outlet line.
