A device which is designed as a rotary-wing craft or as a rotary-wing turbine, the device comprising:
- a rotor module with a motor generator, with rotor blades and with rotary-wing kinematics for the rotor blades connected to the motor generator, the rotor module is designed to enable the rotor blades to rotate in the same or opposite direction on a circular path about an axis of rotation, the rotor blades are each subdivided into a plurality of longitudinal portions for the receptacle of at least one actuator integrated in a longitudinal carrier or transverse carrier of the rotor blade and have a variable, asymmetrical airfoil which, in one revolution of the rotor blade, can be freely oriented at a diameter of the circular path which is freely orientable within an adjustment range with turning points in at least one longitudinal portion of the rotor blade with a length in such a manner that the suction side and the pressure side of the asymmetrical blade profile can be adjusted by means of the rotary-wing kinematics at the turning points from the exterior side to the interior side of the circular path, or vice versa, the interior side being the side of the circular path facing the axis of rotation, the exterior side being the side of the circular path facing away from the axis of rotation, and the variable, asymmetrical airfoil of the rotor blade temporarily has a symmetrical airfoil with its chord aligned tangentially to the circular path in a transitional position;
- wherein the device in the case of the design as a rotary-wing craft is designed in such a manner that the diameter can be aligned with the turning points in the at least one longitudinal portion of the rotor blades with the length transverse to the direction of travel in such a manner that the suction side of the asymmetrical airfoil in both halves of the circular path is oriented in the direction of travel and a thrust force acting in the direction of travel results from the lifting force generated on the asymmetrical airfoil;
- and
- wherein the device in the case of the design as a rotary-wing turbine is designed in such a manner that the diameter with the turning points in all longitudinal portions of the rotor blade can be aligned orthogonally to the flow in such a manner that the suction side of the asymmetrical airfoil can be oriented to the leeward side in both halves of the circular path and a tangential drive force for the rotor blade turbine results from the lifting force generated by the asymmetrical airfoil.
