註釋Force tests 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, a flap-nose overhang 50 percent of the flap chord, and a tab having a chord 20 percent of the flap chord. The results are presented in the form of aerodynamic section characteristics for a sealed an unsealed gap at the flap nose.
