The purpose of this investigation was to find a high regression rate fuel suitable for use as a mixture with hydroxyl-terminated polybutadi- ene (HTPB). Guanidinium azo-tetrazolate (GAT) is the compound that was the focus of our re- search. GAT is a salt containing a high per- centage of nitrogen. It has two conjugated ni- trogen rings, which are negatively charged, and a positively charged component consisting of nitrogen, carbon, and hydrogen. In addition to the high-energy content of this compound, as a salt, it has a lower heat of degradation due to the ease of breaking its ionic bonds.
GAT was found to react with N100, a com- mon curative for HTPB. An alternative isocyan- ate curative was found, polyisocyanate (PAPI), with which it did
