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 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: A hydraulic actuator system of an aircraft includes a hydraulic actuator having a housing with a piston having a piston shaft with a piston head attached thereto and arranged within the housing. The piston head divides in internal volume of the housing into an extend cavity and a retract cavity and the extend cavity is configured to be connected to low pressure fluid source. The system also includes a pressure selector unit fluidly connected to the retract cavity and configured to be connected to the low pressure fluid source and to a high pressure fluid source. The unit include three solenoids with the first and second connected in parallel to the fluid sources and the third solenoid having a third solenoid first input connected to the first solenoid output, a third solenoid second input connected to the second solenoid output, and a third solenoid output connected to the retract cavity.

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.

Abstract: A two stage fuel delivery system for an aircraft includes a first stage pump including an inlet connected to a source of fuel and an outlet connected to a combustor assembly, and a second stage pump including an inlet portion connected to the source of fuel and an outlet portion connected to the combustor assembly. A bypass valve is connected between the source of fuel, the inlet, and the inlet portion. The bypass valve selectively disconnects the second stage pump from the source of fuel. A metering valve is connected to the inlet and the inlet portion. The metering valve includes a metering valve inlet and a metering valve outlet. A pressure regulating valve is connected to the metering valve. A stage monitoring system is configured to detect a change in operation of the second stage and control the bypass valve.
