A flight investigation of the practical problems associated with porous-leading-edge suction

Description: From Summary: "A flight investigation has been made of the practical problems associated with the use of porous-leading-edge suction. The wing leading edge of the test airplane was porous over approximately 83 percent of the span and the first 8 percent of the chord on the upper surface. Various other extents of suction area within these limits were also tested."

Influence of leading-edge suction on lift-drag ratios of wings at supersonic speeds

Description: Note presenting a method based on linearized theory for calculating the theoretical suction force at the subsonic leading edges of a family of wings at supersonic speeds. The method is used to determine the optimum sweepback angles for the tips of trapezoidal wings and to determine the effect of curvature of the tip contour on the lift-drag ratio of wing regions influenced by the tip. Results indicate that appropriately curved tip boundaries will give higher lift-drag ratios in the region affec… more

Low-speed wind-tunnel investigation of leading-edge porous suction on a 4-percent-thick 60 degree delta wing

Description: Report presenting testing of a 60-degree delta-wing-fuselage model with a 4-percent-thick airfoil section with large leading-edge radius in the 19-foot pressure tunnel to determine the effectiveness of porous-leading-edge suction in delaying and reducing the leading-edge separation and accompanying high drag. Results regarding the delta wing, including pump power, lift, pitching moment, pressure distributions, the clipped wing, and some comments on the application of leading-edge suction to del… more
