Abstract
A fuel system for an aircraft includes a main fuel pump, a metering valve fluidly connected to the main fuel pump, a selector valve fluidly connected to the metering valve, a check valve fluidly connected to the metering valve, and an electric motor driven start pump fluidly connected to the check valve and the selector valve. During a start-up condition, the fuel system is configured to permit a fuel to flow through the electric motor driven start pump and through the selector valve to an engine. During a cruise condition, the fuel system is configured to permit the fuel to flow from a high-pressure fuel source and through the electric motor driven start pump start pump to drive the electric motor driven start pump to generate electrical energy.
