Experimental investigation of an NACA 64A010 airfoil section with 41 suction slots on each surface for control of laminar boundary layer

Apr 1952

An investigation has been made of boundary-layer suction through flush surface slots as a means for increasing the extent of laminar flow on the NACA 64A010 airfoil section. The 3-foot-chord model was designed according to an analysis presented herein to maintain nearly full-chord laminar flow at Reynolds numbers up to 25 X 10(exp 6) with the use of 41 suction slots on each surface.
