Abstract: A rotor for an electric machine has winding elements which are arranged in axially running grooves of a rotor body and having a winding head which is arranged axially next to the rotor body. The winding elements exit from the grooves in the axial direction in the region of the winding head and run in the axial direction in the region of the axial ends of the winding elements. Each of the winding elements has four curved portions in the region of the winding head. The rotor includes a plurality of tension bolts and a winding head carrier. The tension bolts connect the winding head to the winding head carrier and penetrate through the winding head radially.

Abstract: In order to suppress aeroelastic instabilities on a transonically operating aircraft comprising a pair of wing halves at which a transonic flow forms spatially limited supersonic flow regions that each, in a main flow direction of the flow, end in a compression shock, a boundary layer of the flow is temporarily thickened-up in at least one supersonic flow region at at least one of the two wing halves, when approaching a flight envelope of the aircraft with increasing flight Mach number of the aircraft. The boundary layer of the flow is thickened-up to such an extent that the compression shock at the end of the respective supersonic flow region at the present flight Mach number of the aircraft induces a separation of the boundary layer of the flow from the wing half.

Abstract: In a method of expanding a flight envelope of an aircraft comprising a pair of wing halves and extendable leading-edge flaps at leading wing edges of the wing halves towards higher transonic flight Mach numbers, at least one of the leading-edge flaps at one of the two wing halves is extended in flight direction, when approaching the flight envelope with increasing flight Mach number of the aircraft.
