    Abstract: A fuel system for a gas turbine engine includes a fuel conditioner. The fuel conditioner has an ice debris separator, a fuel pump, a heat exchanger, and an air oil cooler. The ice debris separator has a fuel inlet and a fuel outlet. The fuel pump connects to the fuel outlet of the ice and debris separator for receiving a fuel flow, pressurizing the fuel flow, and providing the pressurized fuel flow to an outlet of the fuel pump. The heat exchanger is connected to receive pressurized fuel from the fuel pump outlet and has an oil inlet for receiving heated oil, an oil outlet for discharging cooled oil, and a fuel outlet for discharging heated fuel. The air oil cooler is connected to the heat exchanger oil outlet and has an air cooled body configured for further cooling oil from the heat exchanger using an air flow.

    Abstract: A fuel system for an auxiliary power unit includes a mechanical fuel pump, an electric fuel pump, and a controller. The mechanical fuel pump provides fuel flow to the auxiliary power unit and has an output dependent upon an operational speed of the auxiliary power unit. The electric fuel pump is located in flow series with the mechanical fuel pump. The controller causes the electric fuel pump to circulate and thereby warm fuel prior to start up of the auxiliary power unit.

    Abstract: A fuel system is disclosed. The fuel system may include a fuel supply, a fuel supply conduit fluidly connecting the fuel supply to an engine, and a fuel pump in fluid communication with the fuel supply conduit. The fuel system may also include a bypass conduit including a first end fluidly connected to the fuel supply conduit proximate an inlet of the fuel pump, and a second end fluidly connected to the fuel supply conduit proximate an outlet of the fuel pump. The fuel system may also include a bypass valve in fluid communication with the bypass conduit. The bypass valve may be configured to allow fuel to flow from the first end to the second end of the bypass conduit.
