Structural Mechanics of Skewed Thin Wall Systems

Abstract

The general subject of the report is a reinforced conical shell of arbitrary configuration, used as a universal computational model of an oblique thin-walled structure. Under appropriate assumptions regarding the configuration of the directrix of the conical surface and location of its apex, the book discusses, from a unified point of view, different types of wings (straight, swept, low-aspect, delta, etc.) and different types of airframes. The Lagrange variational principle is used to develop a general method of calculation of a reinforced conical shell of arbitrary configuration, amounting to the integration of a system of ordinary differential equations describing the operation of oblique thin-walled systems when the form of external actions is arbitrary.
