COMPOSITION B4, A NON-EXUDING EXPLOSIVE FILLER FOR ARTILLERY SHELL

Abstract

Composition B4 (60/39.5/0.5 RDX/TNT/calcium silicate), a non-exuding explosive, was satisfactorily loaded into Shell, HE, 175mm T203E9. Laboratory test results indicated that this non exuding explosive is less sensitive to impact than Composition B. Safety tests have been conducted on 200 Composition B4-loaded T203E9 175mm Shell. These were fired at chamber pressures from 105- 120% of gun rated pressure and satisfactorily withstood setback pressures of 27,000 psi. Although shells loaded with Composition B4 develop more cracks than those with Composition B they can be fired satisfactorily in all of the currently standard artillery weapons. The sensitivity of RDX/TNT compositions is not adversely affected by commission of the wax, so-called, desensitizing agent.
