Tests of the NACA 64 sub 1 A212 Airfoil Section with a Slat, a Double Slotted Flap, and Boundary-Layer Control by Suction

John H Quinn

Abstract

Report presenting an investigation of the NACA 64(sub 1)A212 airfoil section equipped with a leading-edge slat, a double slotted flap, and a boundary-layer-control suction slot at 0.40 chord to determine the maximum lift coefficients attainable with the high-lift devices alone and in conjunction with one another. Results regarding the effect of suction-slot location on the characteristics of a plain airfoil, plain airfoil characteristics, effect of irregularities caused by slat installation, characteristics of the airfoil with slat extended, characteristics of the airfoil with double slotted flap, characteristics of the airfoil with leading-edge slat and double slotted flap, and a comparison of maximum lift coefficients obtained with various high-lift devices are provided.
