FIELD: test of constructions for action of high-speed strikers. SUBSTANCE: bottom plate has a cup with a blind cavity filled with liquid, whose density equals the density of the striker placed in it. The cup exterior surface is engageable with the interior surface of the split cylindrical extension piece with a membrane, which has a reduced section and is rigidly joined to the interior surface of the extension piece. The membrane reduced section and is rigidly joined to the interior surface of the extension piece. The membrane reduced section and extension piece splits lie in the same plane. The cup is inserted in the extension piece so that the membrane would tightly close the cup cavity. The assembled bottom plate is fired from the barrel. EFFECT: enhanced efficiency. 2 cl, 3 dwg
