| description abstract | An analysis has been made to determine the probable aerodynamic section characteristics of a plain flap with various arrangements of an internal balance. Tests in two-dimensional flow have been made in the NACA 4- by 6-foot vertical tunnel of an NACA 0009 airfoil with an internally balanced flap in order to check the validity of the analytical calculation. The results of these tests, presented in this paper, indicate that the calculations are in agreement with experiment. The analysis has been extended on the basis of the lifting-line theory to include an approximate method for the design of an internal balance for a control surface of finite span. | |
