Abstract
A jet engine includes a shaft rotatably supported in a bearing arrangement, a compressor and a turbine arranged on the shaft, and an electromechanical unit arranged centrally about the shaft axis to provide a motor function for starting the jet engine and/or a generator function for a power supply, and a function of an active magnetic bearing arrangement. The electromechanical unit is embodied as a transverse flux machine. The electromechanical unit preferably includes a rotor carrying permanent magnets and a stator with an undulating profiled stator surface.
