Abstract
Results of an experimental study of the normal collision of cylindrical impactors with sea ice are presented. The dynamics of wave process development in the thickness of a salt ice obstacle and the behavior of the forces of resistance to impactor penetration are analyzed at different impact velocities. The possibility of using induction cross sections for determining the position of impactors in the obstacle in a range of initial velocities of 800-1500 m/s. Pulsed X-ray diffraction is used to obtain motion diagrams (depth versus time) and the dimensions of cavities formed
