THE USE OF EXCESS PRESSURE IN A PARAGLIDER WING TO BLOW OUT A PORTION OF APPROACH FLOW ONTO THE WING UPPER WALL THROUGH A SHAPED SLOT

摘要

The invention relates to aviation, in particular to heavier-than-air vehicles with a flexible wing and is directed at improving the aerodynamic characteristics of a hollow wing provided with an air intake. The technical result is achieved by using a positive pressure inside of a hollow wing for blowing off some of the incoming flow through a convergent channel to the upper surface of said wing in order to form an additional depression zone thereon. The invention can be implemented without substantially modifying the process of the flexible wing production.
