Engineering Development Analysis of a Segmented Projectile Discarding Sabot.

摘要

Developments and studies in hypervelocity conditions near Mach 6.7 show that a segmented projectile is more efficient in terms of penetration than an equivalent monolithic projectile. These projectiles are inserted in a sabot component for the launch. A sabot allows a projectile of a smaller calibre to be fired within a largerbore accelerator. The sabot fills the bore of the gun during the firing stage. Usually, the sabot is a lightweight carrier. This means, the sabot s effect on the core mass must be minimal during the impact with the target. Even if the mass of the sabot is at a minimum; it represents a parasitic mass for the total launch assembly weight. To remove the sabot quickly during flight, it is possible to cut some petals on the sabot wall and put some angle on the front of the petals to help them rotate away from the projectile.
