Abstract
An aircraft engine assembly includes an engine, an engine control actuator responsive to flow of high pressure fuel therethrough for actuating engine controls, a fuel heat exchanger for heating fuel, a fuel controller for controlling flow of fuel in the aircraft engine assembly, a fuel pump having a low pressure section for pressurizing the fuel to a low pressure, and a high pressure section for pressurizing the fuel to a high pressure, an engine gearbox, a seal plate, and a manifold mounted on the engine gearbox and having the fuel pump and the fuel controller mounted thereon, with the seal plate between the fuel pump and fuel controller and the manifold. The manifold provides fuel flow paths between the fuel pump and fuel controller and the several other components of the aircraft engine assembly, replacing the several pipe connections of the prior art. Therefore, it is not necessary to disconnect and reconnect the several pipe connections when removing and reinstalling the fuel pump or fuel controller during repair or replacement. The seal plate assures that leaks are avoided.
