摘要

A new lightweight shell model of the waffle fuel tank of a launch vehicle, which is one of the most critical and expensive components in rocket-and-space engineering, has been proposed. The stress-strain state of the shell has been studied. The obtained results of computational studies can be used to assess the stress-strain state of structural members in rocket-and-space engineering to improve its reliable and safe operation.
