Summary
The results from a stress analysis of a thin skin, foam core, high aspect ratio wind indicate a possible method of constructing sailplane wings, The analysis includes an approximation of the maximum core and skin shear stress, a computer program to evaluate the stress distribution and displacements of a thin walled unsymmetrical tapered cylinder, and the accountablity of creep.
