CRATER FORMATION ON HIGH-VELOCITY COLLISION OF A METALLIC PROJECTILE WITH POLYMETHYLMETHACRYLATE TARGETS

The possibility of using targets made of polymethylmethacrylate for determining the velocity of metallic projectiles is considered. Results of experimental investigations of the interaction of single spherical steel particles of diameter 2.5 mm with polymethylmethacrylate targets in the velocity range 0.94–2.4 km/s are presented. The acceleration of particles is achieved with the aid of a light-gas magnetoplasma launcher. A semiempirical dependence of the depth of penetration of steel projectiles into a polymethylmethacrylate target on the collision velocity has been obtained.
