ГЕРМЕТИЧНІСТЬ ТА ПОЛІКРИСТАЛІЧНІ КОНСТРУКЦІЙНІ МАТЕРІАЛИ

Abstract

Ensuring the tightness of rocketry structures, assemblies, individual structures and systems for various purposes is one of the important aspects of the development, production and operation of technical systems of the present and the future. In accordance with the requirements of the time for the operation and operation of the facility that is being developed, the technologies and means of ensuring tightness are changing. Modern requirements for the tightness of objects of the rocket and space industry, especially for those that are operated in conditions of weightlessness, vacuum, radiation exposure for a long time are extremely stringent.

As shown by the experience of operating tanks designed for storing active rocket components of fuel and, accordingly, to the same extent aggressive, the frequency of loss of functionality due to depressurization statistically has two maximums: at the beginning of operation and a year or two after the start. If the causes and physics of the first are investigated in sufficient detail, then information about the nature of the second in open sources is completely absent.
