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

Claim 11:
12. An aircraft power system comprising:
an internal combustion engine;
a main air mover configured to provide thrust to an aircraft, the main air mover operatively connected to the internal combustion engine;
a turbocharger operatively connected to the internal combustion engine, the turbocharger including:
a compressor for supplying combustion air to the internal combustion engine,
a turbine operatively connected to the internal combustion engine to receive an exhaust flow from the internal combustion engine and convert energy of the exhaust flow into rotational power, and
a turbo shaft operatively connecting the turbine to the compressor to transfer at least some of the rotational power to the compressor;

a generator mechanically connected to the turbo shaft to receive at least some of the rotational power from the turbo shaft for generating electrical power; and
at least one electrically powered air-mover having a thrust producing rotor electrically connected to the generator to receive at least some of the electrical power to produce thrust, the at least one electrically powered air-mover and the generator being electrically connected together, a pressure ratio of the at least one electrically powered air-mover being adjustable using a variable air nozzle of the at least one electrically powered air-mover.
