Effect of Aspect Ratio on the Low-Speed Lateral Control Characteristics of Unswept Untapered Low-Aspect-Ratio Wings

Abstract

A low-speed investigation was made to determine the lateral control characteristics for a series of unswept, untapered, complete wings of aspect ratios 1.13, 2.l3, 4.l3, and 6.13. The wings were equipped with O.25-chord sealed ailerons of various spans and of various spanwise locations. The variation of experimental aileron effectiveness with wing aspect ratio was not accurately predicted for all spans of aileron by any one of the three theoretical methods with which a comparison was made. Design charts based on the experimental results are presented for estimating the aileron effectiveness for low-aspect-ratio, untapered, unswept wings.
