Spar Web Buckling of a Supersonic Aircraft: An Analysis of a Simply‐Supported Rectangular Plate Under the Action of In‐Plane Stresses Due to the Action of Aerodynamic and Inertia Forces and Kinetic Heating Effects

Abstract

SUMMARY An analysis is given for the buckling of a simply supported rectangular plate under the combined action of a number of in‐plane stresses. These stresses could arise in the various plate elements of the structure of a high‐speed aircraft, due to the combined action of aerodynamic and inertia forces with additional kinetic heating effects. The buckling solution of a wing spar web is considered, and the buckling criterion is presented in the form of a determinantal equation which may be evaluated to give the magnitude of the critical thermal stress under a given loading system.
