FIELD: test equipment, mainly used in study of high-speed interaction of solid bodies.
SUBSTANCE: the device has a ring installed in the flight path, its inside diameter is less than the diameter of the bottom plate, but exceeds the striker diameter, and a shutoff device with a hole for passing of the striker and being distant from the ring in the direction of striker flight. Placed in the hole of the shutoff device is a changeable bush, whose inlet and outlet parts of the port are made in the form of bells expanding towards the end faces of the bush, a ring explosive charge is positioned on the inner tapered surface of the inlet bell. The charge may have a variable thickness in contour.
EFFECT: enhanced efficiency of cutting-off of the bottom plate, including cutting-off in the conditions of rarefied atmosphere and vacuum.
