Abstract—
The choice of a transport and launch container (TLC) for analyzing the stress concentration in its elements does not reduce the generality of the proposed methodology for solving problems for other thin-walled structures. The TLC is, as a rule, a cylindrical glass with a spherical bottom, at the pole of which there is a rigid mounting plate. The TLС is loaded by the internal pressure during testing, along the round areas of the spherical bottom during transportation, and by the internal pressure during the launch of the aircraft supported on a rigid plate. In this work, for all cases of loading, design schemes are proposed and the places of localization of stresses in the TPС elements are determined, the sizes of localization and the magnitude of stress concentration are determined on the basis of mathematical models of the mechanics of deformation of shells with an a priori specified error, that is, analytically.
