Assignee: PRATT & WHITNEY CANADA CORP.
Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC B  F | IPC B  F

Claim 0:
1. An aircraft power plant comprising:
an internal combustion (IC) engine using intermittent combustion during operation, the IC engine being drivingly connected to a load via a gearbox to transfer motive power from the IC engine to the load, the IC engine having an exhaust outlet for discharging a flow of first exhaust gas;
a combustor including:
a combustor inlet in fluid communication with the exhaust outlet of the IC engine to receive the flow of first exhaust gas from the IC engine into the combustor;
a fuel injector for injecting fuel into the combustor in which the fuel is mixed with the first exhaust gas and ignited to generate a flow of second exhaust gas; and
a combustor outlet for discharging the flow of second exhaust gas;

a turbocharger associated with the IC engine, the turbocharger including:
a turbine in fluid communication with the combustor outlet and driven by the flow of second exhaust gas, the turbine being drivingly connected to the load to transfer motive power from the turbine to the load; and
a compressor drivingly connected to the turbine and driven by the turbine to compress combustion air for the IC engine; and

a continuously variable transmission, the turbine being drivingly connected to the load via the continuously variable transmission and the gearbox.
