Effect of Flap Blowing on the Sectional Characteristics of an NACA 0015 Airfoil

Abstract

Variation of the maximum lift coefficient, the pressure drag coefficient, leading edge and hinge moment coefficients, angle of attack at stall, and slope of lift curves with different momentum coefficients are investigated. The friction drag is investigated and compared to the pressure drag. Also the moment coefficient required to obtain theoretical flap effectiveness at several flap deflections, an optimum flap deflection for largest increase in lift, and an optimum flap deflection for largest percentage increase in lift are investigated.
