Abstract: The invention relates to a particularly redundant electrical machine (10) for driving a means of propulsion (1) with increased reliability. The machine (10) comprises a plurality of independent partial rotors (210, 220) which are respectively coupled to a common shaft (200) by means of freewheel devices (510, 520) in order to drive said shaft and the means of propulsion (1) therewith in a working direction of rotation. The machine (10) also comprises a plurality of independent stator winding systems (111, 121), a stator winding system (111, 121) and a partial rotor (210, 220) being respectively associated with each other and arranged in such a way that they can electromagnetically interact with each other. The stator winding systems (111, 121) are successively arranged in the axial direction. Similarly, the partial rotors (210, 220) are successively arranged in the axial direction.

Abstract: A gas turbine engine for an aircraft, including the following: a core engine including a turbine, a compressor, and a core shaft connecting the turbine to the compressor; a fan, which is positioned upstream of the core engine, wherein the fan includes a plurality of fan blades; and a gear box which can be driven by the core shaft, wherein the fan can be driven at a lower rotational speed than the core shaft by means of the gear box, wherein the core shaft is designed as a drive shaft for the gear box and has at least one axial first region which has a diameter greater than the diameter of at least one axial second region, wherein the at least one first region is arranged axially between the drive side of the gear box and a mounting and/or attachment on a static part of the gas turbine engine.

Abstract: The invention relates to a stabilization bearing system for a geared turbofan engine, in particular an aircraft engine, with a stabilization bearing for an input shaft device to an epicyclic gearbox device of the geared turbofan engine, the stabilization bearing being located axially in front of an input shaft device location bearing system.
