摘要： A jet engine includes a housing, an intake portion leading into the housing, and an exhaust portion leading from the housing. The exhaust portion includes an exhaust duct and a tail cone arranged radially inwardly of the exhaust duct. An engine portion is arranged in the housing between the intake portion and the exhaust portion. A generator is arranged in the tail cone and is operatively connected to the engine portion. A drive shaft extends from the engine portion to the generator. The drive shaft includes a first end coupled to the engine portion, a second end connected to the generator, and an intermediate portion extending therebetween. The intermediate portion includes a cooling passage that extends from the second end toward a terminal end that terminates short of the first end of the drive shaft.
