Abstract

An assembly is provided for an aircraft propulsion system (22). This assembly includes a compressor section, a combustor section, a turbine section, a flowpath (52), a tail cone structure (88), an electric machine (108) and an electric fan (174A; 174B). The flowpath (52) includes a flowpath inlet and a flowpath exhaust (58). The flowpath (52) extends through the compressor section, the combustor section and the turbine section from the flowpath inlet to the flowpath exhaust (58). The tail cone structure (88) forms an inner peripheral boundary of the flowpath (52) at the flowpath exhaust. The tail cone structure (88) includes an internal volume (142) and an outlet (149) fluidly coupled with the internal volume (142). The electric machine (108) is disposed within the internal volume (142). The electric fan (174A; 174B) is configured to flow air within the internal volume (142) such that the air cools the electric machine (108) and is exhausted from the tail cone structure (88) through the outlet (149).
