DEVICE FOR DIRECTED EXPLOSIVE INCENDIARY AND HIGH EXPLOSIVE-KINETIC ACTION Russian patent published in 2019 - IPC F42B1/32 E21B43/117 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to ammunition intended for destruction of objects located in barrier area of protective structures, and can also be used in means of perforation of oil wells. Device is made in the form of a charge-forming charge with a two-layer lining, which contains a body, an initiation facility, an explosive with a recess placed in the body. Recess is covered with a layer of external pyrotechnical lining and an internal layer. This layer is made of monolithic metal or metal alloy. Outer layer of lining is made massive and is made of pyrotechnic composition. This composition consists of inorganic combustible phosphorus or graphite or their mixture in combinations with metallic fuel based on aluminum particles with additives of metal powders. Ratio of density of pyrotechnic and metal coating is 0.5÷1.3. Ratio of their thickness makes 1÷5. Relative density of pyrotechnic composition is 0.75÷0.98.

EFFECT: higher efficiency parameters of incendiary and high-explosive-kinetic action of the device on objects located in the barrier area of defensive structures.
