Salient features of effect of ground on aerodynamic characteristics of wings are shown with aid of linearized two-dimensional model, followed by description of lifting-surface theory for finite wings of arbitrary planform; theory has been programmed for computer, and effects of ground height, aspect ratio, sweep, taper and nonplanar geometries are investigated; predictions of simplified model are shown to be correct in analysis, namely increase of lift curve slope with decreasing height to chord ratio, rearward movement of center of pressure, and resulting increase in nosedown moment.
