Dynamic pressure surveys were made behind a tapered airfoil to determine the wake characteristics of several flap arrangements, and the application of this type flap to fighter brakes. Results indicated that single or double perforated split flaps may be used as dive brakes without undue buffeting and that they may also serve as fighter brakes. These flaps had approximately the same effects on the wake characteristics of the tapered airfoil as on a comparable rectangular airfoil.
