Patent ID: 6863240

Claim:
A hovering body, especially a helicopter, comprising an autonomous drive to set the hovering body in hovering motion in a free fluid environment, the body having at least one mechanism for optional control of at least one of a directional motion and a position in free space of the hovering body, and the at least one mechanism comprising an elongated basic jacket, which in a direction of its longitudinal axis includes at least one slot jet for controlled ejection of a fluid from an internal environment of the basic jacket into the free fluid environment, the at least one slot jet comprises a cover on its outer side, the cover includes one side connected with the basic jacket and includes another side in the area of its outlet edge set at a distance from the basic jacket, respectively under the cover of the at least one slot jet there is at least one vent passing through the basic jacket, the cover is in the area of the at least one vent set at a distance from the basic jacket for creating outside the at least one vent a turbulizing area which is with the free fluid environment connected by means of an outlet slot between the outlet edge of the cover and the basic jacket, and the aggregate surface of the cross section of the at least one vent under the cover is greater than the surface of the outlet cross section between the outlet edge of the cover and the outer surface of the basic jacket, wherein the basic jacket has a mechanism connected thereto for optional stabilization of at least one of the directional motion and the position in free space of the hovering body, the stabilizing mechanism comprising an elongated jacket closed cover profile where the elongated jacket having connected thereto at least one uplift component, the at least one uplift component having at least one of a convex and a concave surface, wherein the uplift component is configured to produce a force on the elongated jacket when acted upon by a second fluid within the free fluid environment, the uplifting member also having a boarder attack, the boarder attack including a surface area of contact between the uplift component and an external surface of the elongated jacket where the uplifting member mounts to the external surface of the cover profile of the elongated jacket, the surface area includes a continuous curve of inflection points of contact of the uplift component with the outer surface of the elongated jacket, in which in the unrolled shape of the at least one uplift component into a main horizontal plane of symmetry of the basic jacket the ratio of the longitudinal dimension of the boarder attack to a longitudinal dimension of the end place is greater than one, and the mean curve of the traverse profiles, projected on the plane normal to the main horizontal plane of symmetry of the basic jacket makes an arc the angle of whose tangent at the level of the boarder attack is different from the angle of the tangent at the level of the end place of the uplift component.
