Abstract
A high energy propellant comprising 1,3,3-Trinitroazetidine or TNAZ, admi with up to about five percent of cellulose acetate butyrate or CAB by adding the CAB at a temperature slightly above the melting point of the TNAZ. A preferred amount of CAB is from about one percent to about three percent by weight of CAB, based on the weight of TNAZ. When the mixture is melt cast, the crystal structure is finer or smaller than that of pure explosive, producing increased mechanical strength and better resistance to impact. Inclusion of a thermoplastic binder is also contemplated to improve the mechanical integrity of the explosive. Preferred binders are BAMO/AMMO, HYTREL and ESTANE. The formulation permitted inclusion of small quantities of other high explosives because a uniform dispersion was obtained. Preferred high explosive are S-TNT, S-TNB, RDX, HMX and mixtures thereof.
