Missile with distorting casing providing improved internal ballistic characteristics - has concave-ended heavy metal filling bearing against mating internal partition

摘要

The missile has a one-piece casing of tough distorting material with a cylindrical rear guiding portion with a wall thicker than the rear one. At the front it has an ogival head with wall decreasing in thickness towards the tip. The guiding portion is filled with heavy metal, and is sepd. from the filling in the head, tearing the casing open on impact by a partition concave towards the head. The partition is secured to an internal bead where the guiding portion joins the head, and the heavy-metal filling is of truncated cone shape and completely fills the rear portion, having a concave-cone end face bearing against the partition. The head-filling is of non-poisonous fine tin. The wall of the head tapers sharply towards the tip, and contains four fracture points on the inside. ADVANTAGE - Improved internal ballistic characteristics, and more than two-thirds remain together.
