Abstract

A hybrid aircraft power plant (10) includes an air mover (24) for propelling an aircraft (12), a gas turbine engine (14) operable to drive the air mover (24), and an electric machine (46) operable as a motor to drive the air mover (24). The gas turbine engine (14) includes a turbine disk (30) for extracting energy from a stream of combustion gas, and an exhaust duct (38) defining: an exhaust passage for conveying the stream of combustion gas from the turbine disk (30); and a cavity (41) disposed radially inward of the exhaust passage. A shaft (32,50) drivingly connects the turbine disk (30) with the electric machine (46) and extends inside the cavity (41) defined by the exhaust duct (38). A fan (51) is drivingly connected to the shaft (32,50) and operable to circulate cooling air inside the cavity (41) of the exhaust duct (38).
