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.
