The results of the computational and experimental study of the features of the impact of the impactor with the barrier simulating the screen shield of the spacecraft are presented, the pictures of fragmentation of the impactor and the barrier are presented. Numerical calculations were performed using the SPH (Smoothed Particle Hydrodynamics) method. In the experiment, the impactor was accelerated using a two-stage light-gas gun, the state of the barrier and the impactor at the time of their interaction was controlled using x-ray and high-speed video camera. Start-up of the recording equipment was carried out by means of induction sections. The comparative analysis of results of numerical calculation and experiment is given.
