Abstract: A fuel boost pump assembly for an aircraft includes a first inlet for receiving a first pressurized fuel flow, a second inlet, an assembly outlet, a pump for transferring fuel between the second inlet and the assembly outlet, and a hydraulic motor adapted to drive the pump. The hydraulic motor is fluidly connected between the first inlet and the assembly outlet, and is mechanically coupled to the pump. Further, in use, the hydraulic motor converts hydraulic energy of the first pressurized fuel flow into driving energy of the pump such that the pump generates a second pressurized fuel flow between the second inlet and the assembly outlet.
