Jet engine (1), especially for an aircraft, with at least one hollow shaft (7) and/or low pressure shaft (8) rotatably supported in at least one bearing arrangement about a center axis, on which shaft at least respectively one high and/or low pressure compressor (2, 12) as well as at least respectively one high and/or low pressure turbine is arranged, whereby the jet engine (1) further comprises an electromechanical unit (10), in order to provide at least a motor function for starting the jet engine (1) and/or a generator function for the power supply, whereby the electromechanical unit (10) is arranged centrally about the center axis, whereby the electromechanical unit (10) furthermore encompasses the function of an active magnetic bearing arrangement, in order to form at least one bearing arrangement of the at least one hollow shaft (7) and/or low pressure shaft (8), and whereby the electromechanical unit (10) is embodied as a transverse flux machine. Thereby an improved jet engine (1) is achieved, in which means for the bearing support of the at least one engine shaft as well as the means for the power supply of the active magnetic bearing arrangement and of the aircraft as well as the means for starting the jet engine are embodied in a space and weight saving manner and form an integrated unit.
