Wing able to enhance lift power by inner air flow, is solution of wing that results in increased and changeable lift power, with lesser increase of aerodynamic resistance than with conventional wings. In the invention basic embodiment, the wing is provided with free aerodynamic air-flow through a specially designed tunnel (4) running from the opening below the wing front edge (5) to the wing exit edge (6). Turning of the blades (11) enables adjusting of angle of the air flow (13) exiting from the tunnel (4), and their synchronous turning with the gate (15) enables partial or complete closing of the tunnel (4) and turning of the wing into a l conventional wing with closed profile contour. The principle of this technical solution is applicable, with adequate adjustments, to glider-paraglider and kite wings, made of fabrics, and to wind-generator rotor wings. |
