Problems solved by technology

However, the friction coupling taught by this publication does not allow a sufficiently reliable fastening of the supporting parts
In addition, the dimensions of the support parts and the control fins always exhibit certain deviations in manufacture which cause variations in the values ​​of the fastening force

Embodiment Construction

[0024] In FIG. 1 a a projectile 1 is arranged in a barrel 2 of a breech-loading weapon. The weapon may be a mortar, wherein the inner surface of the barrel 2 is generally smooth. The end portion of the shell 1 comprises a tail pipe 3 and control fins. Tail 4 includes one or typically a plurality of control fins, which are used to influence the trajectory of shell 1 . The details of the structure of the projectile 1 may differ from that shown in the figures. The latch and other details of the weapon are not shown for clarity. A support element 6 according to the invention is fastened to the tail 4 in order to hold the shell 1 in place in the barrel 2 until it is fired. The rim flange 7 in the support element 6 prevents the projectile 1 from moving forward in the barrel 2 when the barrel 2 is oriented horizontally or even when the barrel 2 is oriented downwards. Furthermore, the rear surface of the weapon barrel can be provided with grooves or notches in which the rim flange...

Abstract

The invention relates to an arrangement for supporting a shell (1) into a barrel (2) of a breech-loading weapon, the arrangement comprising a rim-flanged support element (6) attachable to a shell tail (4). The arrangement is characterized in that the arrangement comprises a propelling charge element (12) comprising a propelling charge (14) and a primer (13), the element having a threading (15a) suited for the shell tail allowing the support element (6) to be fastened to the shell tail by threading the propelling charge element (6) into the tail of the shell (1) through the support element (6). The invention further relates to a method of supporting a shell into a barrel of a breech-loading weapon.

Description

technical field [0001] The invention relates to a device for supporting a projectile into a barrel of a breech-loading weapon, the device comprising means for fastening a flanged support element to the tail of the projectile. [0002] The invention also relates to a method for fastening a support element to a projectile, in which method the support element comprising a rim flange is fastened to the tail of the projectile. Background technique [0003] The mortar can be arranged on a movable base, for example on an armored vehicle, allowing the mortar to be easily moved from one place to another and, on the other hand, to be moved quickly from the emplacement to a safe place . If the mortar is intended to be fired horizontally or downwards, the problem is that the shell does not stay in place in the mortar's smooth barrel, but instead slides forward in the barrel so that it can no longer be fired emission. US Patent 5,503,080 discloses a support member which is frictionall...
