Investigated is the destruction of a duralumin barrier under the action of an aluminum jet (analogue of an elongated striker) at a speed of 7 - 11 km / s in the presence of copper and aluminum metal screens. The fraction of the effectiveness of the spacecraft shield, determined by the scattering of parts of the destroyed striker between the screens, is highlighted. An increase in the efficiency of the screen protection due to the phase transitions of the interacting materials of the striker and screen is determined.
