1. An aircraft power plant comprising:
an internal combustion engine using intermittent combustion during operation;
a turbocharger associated with the internal combustion engine, the turbocharger including:
a turbocharger turbine configured to be driven by a flow of exhaust gas from the internal combustion engine; and
a turbocharger compressor drivingly engaged with the turbocharger turbine and configured to compress combustion air for the internal combustion engine; and
a heat engine using supercritical carbon dioxide (sCO2) as a working fluid to convert heat into mechanical energy, the heat engine being in thermal communication with the exhaust gas downstream of the turbocharger turbine.
