Abstract: The disclosure relates to an electrical machine that includes: a stator that forms a cylindrical inner face; a rotor configured to rotate inside the stator about a longitudinal axis that defines an axial direction, the rotor forming a cylindrical outer face; and an air gap formed between the cylindrical outer face of the rotor and the cylindrical inner face of the stator. Apparatuses and mechanisms are provided for providing an air flow in the air gap, wherein the air flow flows in and/or counter to the axial direction in the air gap. The disclosure also relates to methods for cleaning an air gap in an electrical machine.

Abstract: An automated method for influencing a gust load of an aircraft is provided. A torque at least of an electromotive thrust generating unit arranged on a wing of the aircraft is modified such that a root bending torque of the wing generated by the gust load is reduced. An associated apparatus, an aircraft, a computer program product, and a computer-readable medium for carrying out the method are also provided.

Abstract: The invention relates to an automated method for influencing a gust load of an aircraft (6), wherein the torque (MI) at least of an electromotive thrust generating unit (1) arranged on a wing (4) of the aircraft (6) is modified such that the root bending torque (M2) of the wing (4) generated by the gust load is reduced. The invention also relates to an associated apparatus and an aircraft and a computer program product and a computer-readable medium for carrying out the method.
