METHOD OF CREATING LIFTING FORCE FOR VERTICAL TAKEOFF FLYING VEHICLE |
摘要 |
FIELD: aviation. ^ SUBSTANCE: proposed method includes suction of air from upper surface of wing by means of impeller of centripetal fan and directing this air flow under lower surface of wing with the aid of centrifugal fan impeller. Air flow formed in radial direction relative to annular wing having asymmetric profile creates lifting force due to difference in pressures on lower and upper surfaces of wing. ^ EFFECT: enhanced efficiency of creating lifting force. ^ 2 cl, 1 dwg
