DEVICE FOR FORMING HIGH-SPEED ELONGATED FLUTED ELEMENT, INCLUDING SELF-WINDING ELEMENT Russian patent published in 2019 - IPC F42B1/02 F42B1/28 

FIELD: military equipment.

SUBSTANCE: invention relates to defense equipment and can be used in various cumulative ammunition (CA) intended for hitting targets by high-speed striking elements (SE). Device consists of a fuse, a body with an explosive charge enclosed therein and having a recess coated with a metal lining of a combined shape, and an initiation device with an annular arrangement of initiation points on the charge end face. Metal lining has a spheroconical shape, and the initiation points on the charge end face are located on one or several circles with a radius smaller than the charge radius. Position of the initiation points on the charge end face is set by radii of the enclosed circles, counting from the end face centre, with their simultaneous initiation. Position of the initiation points on the charge end is set by an arbitrary curve, for example, a spiral, counting from the centre of the end face. Position of the initiation points at the charge end is set by an arbitrary curve, for example, a spiral, wherein initiation of detonation of the charge at the initiation points occurs with a time delay, counting from the centre of the end.

EFFECT: invention allows forming a self-winding high-speed elongated element.
