Abstract

A hybrid aircraft power plant includes an air mover for propelling an aircraft, a gas turbine engine operable to drive the air mover, a bifurcated exhaust duct conveying combustion gas from the gas turbine engine, and an electric motor mounted to the exhaust duct and operable to drive the air mover. The turbine engine includes a turbine extracting energy from an annular stream of the combustion gas and being rotatable about a rotation axis. The exhaust duct includes a first branch conveying a first portion of the combustion gas toward a first direction away from a rotation axis of the turbine, and a second branch conveying a second portion of the combustion gas toward a second direction away from the rotation axis.
