METHOD FOR DETERMINING HEIGHT OF DETONATION OF COMMON SHELL OVER GROUND Russian patent published in 2018 - IPC F42B35/00 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to ammunition and can be used to assess the functioning of non-contact fuses. Before the tests of non-contact fuzes, a shell with a contact fuze is conducted in the shell. In the funnel formed during the explosion, measure the depth of the funnel h_f. Then carry out firing using non-contact fuzes in the same shells, with the same aiming gun. In the funnels formed during the explosions of shells, the funnel depth h_f^H is also measured. Height of the detonation of the shell above the surface of the ground is estimated by calculation using the relation H=(h_f-h_f^H)/(l-η), where H is the height of the detonation of the shell above the ground; h_f – the depth of the funnel in the ground when the shell is blown up by means of a contact fuse; h_f^H – the depth of the funnel in the ground when the shell is blasted by means of a non-contact detonator at a height H; η – the empirical (tabular) coefficient of interaction of the explosion with the underlying surface.

EFFECT: increased reliability of the evaluation of the parameters of the test of non-contact fuzes, in particular, increased reliability of determining the height of detonation of shells with non-contact fuzes.
