CARTRIDGE HEAD PART Russian patent published in 2019 - IPC F42B12/58 

FIELD: rocket equipment.

SUBSTANCE: invention relates to rocket engineering and can be used in development of multiple rocket launchers with large combat elements. Cloth head part comprises fairing, shell, in-series located payload elements with boost assembly and piston connected by means of accumulating cavities. Elements of payload with diameter of not less than 1.08 times inner diameter of cover of head part are rigidly connected to each other by means of two segmented semi-rings in each connection. Their length is not more than 1/4 of the gauge, with cowling and piston of the forcing assembly located in the bottom part. At that accumulating cavities are connected by gas-water channels formed by inner surface of shell and outer shell of elements of payload with depth of internal radial notch of shell not more than 1/2 of thickness. At their ends between zones of attachment of semi-rings there are lowerings, providing gas-thermal connections between elements of payload. On the piston the obturating rubber collar is fixed.

EFFECT: increased efficiency of destruction and reliability of functioning of head part at separation on flight trajectory.
