SHELL BODY Russian patent published in 2017 - IPC F42B12/24 F42B14/02 

FIELD: weapon and ammunition.

SUBSTANCE: shell body is made in the form of a glass with a curved taper. A threaded opening for the fuse is made in the this part. The chamber is equipped with distributed longitudinal and transverse corrugations, forming semi-finished damaging elements at the intersection. Curvilinear conjugation is formed between the head part of the chamber and the shank by means of reduction - an undercut with the body wall thinning. The pitch between the transverse corrugations of the shank is 2-5 times as the pitch between the longitudinal corrugations of the chamber.

EFFECT: increase in the destructive fragmentation effect due to the formation of different fragments in the form, mass and initial velocity, which provide a complex damaging effect, spaced in time.
