NACA-WR-L-448
Wind-tunnel investigation of control-surface characteristics VII - a medium aerodynamic balance of two nose shapes used with a 30-percent-chord flap on an NACA 0015 airfoil
Year: 1942
Abstract: Force-test measurements in two-dimensional flow have been made in the NACA 4- by 6-foot vertical tunnel of the characteristics of an NACA 0015 airfoil with a balanced flap having a chord 30 percent of the airfoil chord and a flap-nose overhang 35 percent of the flap chord. The effect on the aerodynamic section characteristics of the shape of the flap-nose overhang and the gap at the flap nose was investigated. A few tests were made to determine the effectiveness of a 20-percent-flap-chord tab on the balanced control surface.
