Abstract

A jet engine, in particular for an aircraft, having a high-pressure compressor that is situated inside a compressor housing, the high-pressure compressor having blade elements that, through their rotational motion, compress air flowing into the high-pressure compressor via an intake channel, the high-pressure compressor having a plurality of compressor stages on which the blade elements are situated, and the jet engine also having an integrated electric motor/generator unit, wherein the motor/generator unit is situated in the rotational plane of the at least first compressor stage of the high-pressure compressor, and includes a stator that extends around the periphery of the compressor housing, as well as a runner that is formed by the blade elements of the at least first compressor stage, and that the motor/generator unit has an output power of 100 kVA to 150 kVA.
