ABSTRACT:
Methods of and apparatus for controlling the separation of a boundary layer from a surface on which an adverse pressure gradient exists. A streamwise jet of fluid is so discharged onto the surface at a location adjacent the juncture between the surface and an adjoining structure as to energize the boundary layer and thereby delay the separation of the boundary layer from the airfoil in the vicinity of that juncture.
