Abstract: A scheme for obtaining and detecting high-velocity compact metal elements moving with hypersonic velocities under high-intensity shock loading is developed. A light-gas ballistic device and shadow photography are used for this purpose. Application of the hemisphere – cylinder cladding makes it possible to test a cumulative charge steadily forming in a compact steel element, moving with a velocity approximately equal to 6 km/s. The results of the numerical and experimental testing of this projecting device are given.

Keywords: resistance to meteoroids, cumulative charge, compact element, impact loading, explosive projecting device.
