An airfoil-shaped body has a relatively thin trailing edge with a series of alternating, adjoining, downstream extending troughs and ridges in its suction surface which form wave-like surface undulations terminating at the trailing edge. The ridges in the suction surface form corresponding troughs in the pressure surface near the trailing edge; and the troughs in the suction surface form corresponding ridges near the trailing edge of the pressure surface. The resulting airfoil-shaped body has a trailing edge with a wave-like shape. The trough and ridge c...


In an airfoil shaped body having a thin trailing edge, a trailing edge region, and a pressure and a suction surface terminating at said trailing edge, and adapted to be disposed in a fluid moving downstream relative thereto at a selected operating angle of attack A which would normally result in flow separation from said suction surface, means for preventing or delaying such separation from occurring on said suction surface at such angle of attack comprising: a plurality of alternating, adjacent troughs and ridges in said suction surface extending to sai...
