description abstractAerodynamic characteristics of a rectangular NACA 23012 airfoil with single and double perforated split flaps have been determined in the NACA 7- by 10-foot wind tunnel. A large range of flap spans and deflections and a large range of spanwise and chordwise locations of the flaps were investigated. Dynamic pressure surveys were made behind the wing at the approximate location of the tail, in order to determine the extent and location of the wake for each flap arrangement. Tests were also made with a full-span plain flap to determine the effect of the various split-flap arrangements on aileron control.
