Abstract

INTRODUCTION <br>The recent trend toward the use of low-aspect-ratio wings for high-speed flight requires that the low-speed stability and control characteristics of such configurations be determined. Some work has been done to determine the static stability characteristics of unswept low-aspect-ratio wings (for example, reference 1). The present investigation was undertaken to extend this work to include the damping-in-roll and static stability characteristics of both swept and unswept low-aspect-ratio wings. The swept wings were of triangular or approximately triangular plan form. <br>This investigation consisted of force and damping-in-roll tests of 18 wings having different aspect ratios, taper ratios, and sweepback angles. Most of the wings were of low aspect ratio (ascot ratio &lt; 3) although four wings of higher aspect ratio were included for comparison.
