FIELD: aeronautical engineering. ^ SUBSTANCE: aircraft bearing surface with section structure comprises a wing incorporating means of increasing lift and a bearing aerodynamic surface arranged on the lift increasing means inner structure above and below the said means. The bearing aerodynamic surface represents and upper and lower skins terminating at the lift increasing means front and rear edges and passing in direction of the said means span. The aforesaid lift increasing means is arranged in the wing tail part and hinged thereto at three points. The upper and lower skins are furnished with several chute-like elevations arranged at a distance from each other in the wing span direction. The shape of the said elevations, starting from the rear edge, is selected towards the inner structure section central line, while their height decreases as the distance to the front edge decreases. ^ EFFECT: perfected aircraft aerodynamics. ^ 13 cl, 9 dwg |
