    摘要： 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 provides fuel flow to the auxiliary power unit, and is located in flow series with the mechanical fuel pump. The controller causes the electric fuel pump to provide fuel flow during starting of the auxiliary power unit.

    摘要： 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.

    摘要： 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.

    摘要： An example method of fuel delivery to a turbomachine includes reaching a light-off speed of a turbomachine and delivering fuel to a combustor of the turbomachine at a first rate. The method also increases the rate of the delivery. The combustor achieves light-off at a fuel flow rate on or in-between the first rate and a second rate that is greater than the first rate. An example turbomachine fuel delivery assembly includes a fuel delivery component and a controller configured to adjust the fuel pump to increase a rate of fuel delivery from a fuel supply to a combustor of a turbomachine.
