ELECTRIC DISTRIBUTED PROPULSION USING EXHAUST RECOVERY POWER

An aircraft power system (100) comprises a turbocharger (104), the turbocharger (104) including a compressor (108) for supplying combustion air to an internal combustion engine (102), a turbine (110) operatively connected to an internal combustion engine (102) to receive an exhaust flow from the internal combustion engine (102) and convert energy of the exhaust flow (114) into rotational power and, a turbo shaft (112) operatively connecting the turbine (110) to the compressor (108) to transfer at least some of the rotational power to the compressor (108). A generator (116) is operatively connected to the turbo shaft (112) to receive at least some of the rotational power from the turbo shaft (112) for generating electrical power. At least one electrically powered air-mover (118) is electrically connected to the generator (116) to receive at least some of the electrical power to produce thrust.
