Abstract
The invention deals with the manufacture of fully segmented sabots used in he launching of subcaliber projectiles. The prior method required the machining of individual sabot segments and fitting them on to the sub-projectile. The improvement involves the casting of the sabot segments with the shimmed sub-projectile pre-positioned in a mold.
Claims11
A method of making cast-in-place sabot for a sub-projectile which comprises the steps of:
- (a) preparing a plurality of shims with a profile on one edge matching that of the profile of the sub-projectile and a profile at the other edge matching that of the inner contour of a casting split mold;
- (b) coating the split mold with a release agent;
- (c) assembling the shims on the sub-projectile with means designed to fix them to the sub-projectile;
- (d) coating the fixing means with a release agent;
- (e) applying a release agent to all shim and sub-projectile surfaces to come in contact with a subsequently cast material;
- (f) placing the sub-projectile and shim assembly in the mold;
- (g) fastening the mold sections together;
- (h) casting the mold with a liquid that will subsequently harden, creating the sabot segments;
- and
- (i) stripping the mold and the shim fixing means from the sub-projectile.
