Some Effects of Kinetic Heating on the Stiffness of Thin Wings‐II: Analysis of Flexural and Torsional Stiffnesses for Large Deformations of Thin Solid Wings

Abstract

The Third Power Approximation introduced in the previous section is here applied to determine the stiffness characteristics of symmetrical double‐wedge wings subjected to large flexural and torsional deformations. This method is believed to yield results of sufficient accuracy for practical purposes, even for wings with a thickness/chord ratio as low as 3 per cent, as long as the spanwise curvature and the maximum stresses are in the range of engineering applications. As mentioned in the Introduction it is also possible to derive an exact solution in terms of Bessel functions but its complexity limits its practical interest.
