1. A method of driving a load onboard an aircraft, the method comprising:
transferring motive power from an internal combustion (IC) engine to the load, the IC engine using intermittent combustion during operation;
discharging a flow of first exhaust gas from the IC engine when transferring motive power from the IC engine to the load;
receiving the flow of first exhaust gas from the IC engine into a combustor;
mixing fuel with the first exhaust gas in the combustor and igniting the fuel to generate a flow of second exhaust gas;
receiving the flow of second exhaust gas at a turbine and driving the turbine with the flow of second exhaust gas from the combustor; and
transferring motive power from the turbine to the load,
wherein:
mixing fuel with the first exhaust gas in the combustor and igniting the fuel to generate the flow of second exhaust gas is performed during momentary peak power operation of the aircraft; and
after the momentary peak power operation, the method includes:
ceasing to mix fuel with the first exhaust gas and igniting the fuel in the combustor to generate a flow of second exhaust gas; and
receiving the flow of first exhaust gas at the turbine and driving the turbine with the flow of first exhaust gas.
