Paper Abstract

Results of the laboratory experimental investigation of the impact against the barriers of a number of materials by the shower (bunch) of tungsten particles (striker) having density equal to 1 g/cm3, mass equal to 0.2 g and velocity up to 24 km/s as well as their head-on collision with relative velocity equal to 48 km/s, the results of analysis and prediction are presented. By using filming with illuminating from explosive the registration has been realized. Penetration, reactive pulse and the character of energy release during the shower deceleration were studied. In the experiment the process development pictures (partial explosion during impact and subsequent penetration) which appeared to be intermediate between the complete explosion of the striker on the surface of the barrier and the explosion in the barrier after penetration has been realized. The hypervelocity collision process is also necessary to consider, to investigate and to develop as a system being possessed of its specific properties. The results presented in the report make possible to predict the explosion parameters for the wide range of strikers and barriers. The bases of new generalized approach to the problem of the impact action control are outlined. It is shown that in spite of the variety of its practical usage the process of collision can and must be considered as the system. It is stated that the basis and the tool to control the impact action is symmetry in all the diversity of its forms and violations.
