Sub-calibre-propelling cage projectile with gas pressure sepn. - having extended propelling cage, hollow cylindrical section, segments and annular gap

摘要

A sub-caliber propelling-cage projectile with differential gas pressure operated propelling-cage separation comprising the projectile (1) and propelling-cage (2), whereby in the rearwardly extended propelling-cage (2) a hollow cylindrical section (3) is fitted, the latter having a smaller external diam. than the propelling-cage (2) as well as a smaller O.D. than the inner diam. of barrel (4), thus defining an annular gap (5) between section (3) and the inner wall of barrel (4), so that when the projectile (shell (1) and propelling cage (2)) exits the barrel (4), the pressure drop in annular gap (5) commences earlier in time than inside section (3). The inner wall of section (3) is thus subjected to the pressure differential generated and the segments from the multi-subdivided propelling-cage (2) and section (3) carry out a movement perpendicular to the longitudinal axis of projectile (1) - (separation of the propelling-cage (2) from the projectile (1)). USE/ADVANTAGE - The arrangement can be used for a subcaliber propelling-cage projectile with gas-differential operated propelling-cage separation. The projectile is subjected to no or very minor interfering forces during the separation process of propelling-cage from the projectile, thus increasing the chance of hitting the target.
