198 Method and system for preventing base separation of cast explosives in projectiles US194314 1980-10-06 US4365556A 1982-12-28 Paul F. Reibel
Base separation of cast explosives in projectiles is prevented by means of resilient device, such as a spring washer, positioned between the bottom of the fuzewell cavity in the cast explosive and the bottom of the fuzewell liner threadedly secured to the projectile. By tightening the liner, the spring washer is compressed, causing it to apply a force upward on the liner and downward on the cast explosive toward the base of the projectile, thereby allowing the cast explosive to move in response to thermal changes while maintaining it in contact with the projectile base at all times.
199 Shaped charge warhead with mechanical means for preventing rotation US161710 1980-06-23 US4342261A 1982-08-03 John N. Majerus
Mechanical interference between a cast explosive material and a casing prnts rotation of the cast explosive material during machining thereof and improves symmetry and performance of the shaped-charge warhead. The cast explosive material may be keyed to the casing by flowing portions of the explosive material into a plurality of cavities in the casing before curing. Alternatively, pins may extend inward from the casing into the explosive material which surrounds them when cast and resists relative motion therebetween when cured. Alternatively, the explosive material may be pre-cast into an appropriate shape, cured and pressed into the casing. Protuberances to fit into holes in the casing or indentations to fit over pins extending into the casing may be formed on the pre-cast explosive. Engagement between the protuberances or indentations and the holes or pins respectively is attained when the explosive material is pressed into the casing.
