On the Potential Flow About an Airfoil in Ground Effect and Undergoing Unsteady Motion.
Abstract
A computer solution employing Pistolesi's theorem and the method of images has been developed to determine the potential flow about an airfoil in ground effect undergoing unsteady motion. The airfoil mean camber line is broken into a finite number of straight line segments. Vortices are used to model the airfoil potential and the wake potential. Although the solution is restricted to thin airfoils, it is not restricted to small angles of attack or small camber. Solutions of an airfoil undergoing harmonic motion and a C-130 short take-off maneuver are presented.
