FIELD: aerostatic; reduction of resistance force. SUBSTANCE: creation of lifting force for helicopter, for example, is ensured by rotation of blade at similar angular velocity about horizontal axis and revolving axle perpendicular to it in such way that positive angle of attack is directed towards motion at all times and trajectory of motion has form of lemniscate. EFFECT: enhanced efficiency. 1 dwg
