FIELD: aerodynamics; designing of flying vehicles, organization of aircraft motion in water. ^ SUBSTANCE: proposed method consists in forming regular structures for finding the conditions when axis of natural vortices is directed not in way of flow but at any angle required by conditions of flow. Infinite sequence of artificial vortices is similar to roller bearing located between body and medium. Proposed method provides for creating the lifting force for flying vehicle on base of proposed model of flowing around solid bodies by continuous media. Proposed method consists in forming the determined vortices on upper surface of wing which are directed to overwing flap where they are broken. Vortices rolling over upper surface of wing without sliding increase in size. Their destruction within overwing flap results in increase of pressure, thus creating lifting force for aircraft. ^ EFFECT: enhanced efficiency. ^ 8 cl, 8 dwg |
