DEVICE FOR PROTECTION FROM CUMULATIVE JET AND SHELL OF EXPLOSION Russian patent published in 2018 - IPC F41H5/04 

FIELD: armored structures.

SUBSTANCE: invention relates to armored structures, installed particularly in special purpose chambers. Device for protection against cumulative jet and explosion fragments contains protective block installed in direction of damaging effect in front of protected object, It is made in form of closed chamber filled with protective elements. Coaxial to block in front of object to be protected, housing is placed in anti-fragmentation net damper in form of, for example, glass with thickened bottom, rigidly connected with surface of protected object. Glass cavity is filled with multilayer armor, thickness of which is determined depending on jet length, layers material density and material, from which cumulative jet is formed. Armor is recruited from layers of high-density material with possibility of alternating them with one or several layers of lower density. Layers are oriented indirection of damaging effect. Protective elements are rolling elements made of high-density material.

EFFECT: dynamic loads reduction on protected object is achieved.
