DEVICE FOR DETERMINING EXPLOSIVE CHARGE / AMMUNITION EXPLOSION PULSE IN THE NEAR ZONE Russian patent published in 2018 - IPC F42B35/00 G01N33/22 

FIELD: blasting operations.

SUBSTANCE: device for determining the explosive charge / ammunition explosion pulse in the near zone comprises a support structure consisting of a shelf with a horizontal surface and a vertical post / posts for its fastening and a set of prismatic meta bodies exposed to the impacting factors of explosion, placed on the shelf. Bodies thrown are made in the form of regular prisms, the lateral edges of which are longer than the sides of their bases, and are mounted on the support structure in several rows in height, forming a fragment of the honeycomb surface of a given profile with its frontal surfaces. On the back side, bodies thrown are equipped with equal mass indicator elements placed in each horizontal stacking row at different heights relative to their support surfaces. Bodies thrown are made in the form of rectangular parallelepipeds, regular triangular or hexagonal prisms. Meta bodies can be made hollow, and their cavities are filled with loose or hardening material of a given density. Indicator elements of the bodies thrown can be made in the form of rods, and have a different length within the horizontal stacking row. For more accurate measurements, indicator elements are placed at different distances from the equally oriented side surfaces of the bodies thrown within the vertical stacking row.

EFFECT: invention makes it possible to improve the accuracy of measurements.
