Separated laminar flow boundary layers are stabilized by delaying a transition into a turbulent flow and by reducing the size of the laminar boundary layer separation zone downstream of a disturbance in the surface contour of a body in the flow, such as a backward step in the body surface, e.g., where sheet metal layers overlap in the surface of an aircraft wing. This purpose is accomplished by suction inlets in the surface just upstream of the disturbance and blowing outlets just downstream of the disturbance and by a flow channel interconnecting these ...


A method for stabilizing laminar, separated boundary layers of a medium flowing in a given flow direction along a boundary surface of a body in said flowing medium, by boundary layer control, comprising the following steps: (a) determining in a first zone, where there is a relatively high static pressure, first points on said boundary surface of said body upstream of and directly at a laminar boundary layer separation location (1) forming a disturbance in said boundary surface, (b) determining in a second zone, where there is a relatively low static pres...
