Abstract

At present, modern spacecraft use high-precision equipment that is sensitive to influence impacts. In this regard, there is a need to create shock-free trigger devices for mechanisms for holding and releasing movable structural elements. These tasks determined the vector of development of electromechanical trigger devices that do not contain pyrotechnic devices in their design. Along with the new tasks, there are constant problems of rocket and space technology – the improvement of mass-dimensional characteristics. However, pyrotechnic elements force the use of massive housings and brackets for structures that can withstand a sharp increase in pressure and the impact of the executive parts. The use of universal pyropatrons does not always allow optimizing the design of the retention mechanism. Also, one of the disadvantages of working with pyrotechnic media is the increased risk of working. The paper presents the results of a study of the possibility of modernizing the design of trigger devices, improving their mechanical and electrical characteristics. The research was carried out using calculated and experimental methods, and experimental samples of trigger devices were manufactured and released. As a result of the work, an upgraded trigger device was developed, better electrical characteristics were achieved, power consumption was reduced (the response time was reduced), mass-dimensional characteristics were improved, and the number of structural parts was reduced.
