Contribution to studying the structural analysis of rocket fuel

Abstract

A brief review of possible stresses and deformation of rocket fuel while stored, in its preparation for exploitation and in the course of exploitation. The procedure of its structural analysis is described and shortcomings of the calculation based on the viscoelasticity of material are listed. On the basis of own research and experience from the other countries is underlined the need that for getting the more precise results in the structural analysis it should be performed with taking into account the non-linear viscoelasticity of the rocket fuel.
