Method for producing a large-caliber explosive projectile

摘要

A method is provided for producing a large-calibre explosive projectile having a projectile casing with an ogival front part, which surrounds an internal area filled with a plastic-bonded explosive charge and, at a nose end, has a mouth closed by a nose fuze, wherein an elastic liner is arranged between the explosive charge and the inner wall of the projectile casing. The projectile casing is produced in two parts, such that, in the direction of the longitudinal axis of the projectile casing, a tail-end projectile casing section and an annular front projectile casing section, which contains the mouth, can be connected to one another in the area of the ogival front part, via a screw connection. The liner is introduced into the tail-end projectile casing section and the explosive charge is introduced into the liner before the two projectile casing sections are connected to one another.

1. A method for producing a large-caliber explosive projectile comprising a projectile casing provided with an ogival front part, wherein the projectile casing surrounds an internal area of the explosive projectile that is filled with a plastic-bonded explosive charge, and the projectile casing has a mouth hole at a tip end, wherein a nose fuze is disposed to close the mouth hole, wherein the method comprises the steps of:
(a) producing the projectile casing as an at least two-part casing comprising a tail-end projectile casing section and an annular front projectile casing section that contains a mouth hole, wherein in a direction of a longitudinal axis of the projectile casing, the annular front projectile casing section is disposed in front of the tail-end projectile casing section so that the annular front projectile casing section and the tail-end projectile casing section are connectable to one another via a screw connection in an area of the ogival front part; (b) before connecting the annular front projectile casing section to the tail-end projectile casing section, matching a liner to an internal contour of the internal area of the explosive projectile, wherein the liner comprises an elastic material, and introducing and positioning the liner into a first portion of the internal area that is in the tail-end projectile casing section, wherein the liner is introduced and positioned into the first portion of the internal area through a front-end opening of the tail-end projectile casing section; (c) then introducing the plastic-bonded explosive charge into the liner and, after the plastic-bonded explosive charge is cured, closing the liner using a cover, and forming a seal between the liner and the cover; (d) then positioning an elastic compensation element that is matched to an internal geometry of the annular front projectile casing section on the cover, and connecting the annular front projectile casing section to the tail-end projectile casing section so that the annular front projectile casing section and the tail-end projectile casing section are screwed to one another.
