The Effect of Wing Bending Deflection on the Rolling Moment due to Sideslip

Abstract

A method is presented for calculating the effect of wing flexibility on the rolling moment due to sideslip for wings of various aspect ratios and taper ratios when different shapes of the bending-deflection curve are assumed. The shape of the deflection curve is shown to be unimportant, the main factor being the amount of wing-tip deflection. An accurate and an approximate method for calculating the tip deflection are given. The effect of wing flexibility on the rolling moment due to sideslip seems to be large enough to be if appreciable importance in the design of large low-load-factor airplanes.
