SEPARATED FRAGMENTATION-DEMOLITION HEAD PART OF PROJECTILE Russian patent published in 2020 - IPC F42B12/58 F42B15/36 

FIELD: rocket equipment.

SUBSTANCE: invention relates to the field of rocket equipment and can be used in development of jet projectiles with separated head parts of fragmentation-demolition action. Proposed device comprises case with fairing, combat compartment with explosive charge and ready fragments, as well as separation, stabilization and detonation systems, gas-dynamically interconnected by means of central gas duct equipped with head chamber to accommodate command initiation device. Combat compartment has block of ready fragmentation sleeves as means of destruction. They are arranged on cylindrical part of housing. At the same time the combat compartment is equipped with the anticipatory device made in the form of a hollow conical skirt, which thrusts interacting with the bottom of the compartment and with the head chamber made in the form of a cup. Bottom part of the cup is rigidly attached to the central gas line. Front part of the cartridge is attached to the fairing. Detonation system is made in the form of two cascades. They include the main and duplicating detonating circuits closing in detonators of the front and rear belts of the detonation, equipped with receiving detonator blocks located in front disk of the gas line. Main detonating chains thermodynamically connected to each other by means of detonation cords laid in longitudinal slots on the outer diameter of the gas duct are additionally equipped with transverse and reverse detonation cords. They are arranged on outer diameter of gas duct and have on each detonation section total length equal to half of length of main detonation cord, providing possibility of transfer of initiating pulse from receiving detonator grain to bottom detonator. In the longitudinal groove at the place of passage of the main detonation cord through the area of the front detonator arrangement, there is a radial recess filled with an inert compound. In the front part of the hollow skirt a strong crosswise bridge is installed, covering a zone of effective power action on the front belt of detonation at operation of receiving detonation blocks.

EFFECT: high reliability of the device owing to high reliability of outputting the igniting and detonation pulse and protecting the device units from abnormal operation.
