Development and Test of a Highly Energetic DOMINO Propellant
Abstract
This program was designed to demonstrate a practical high energy propellant containing a difluoroamino binder, AlH3, and the advanced oxidizer hydroxylammonium perchlorate (HAP). There were several problems which had to be solved before the attractive specific impulse and density of this advanced system could be realized in a practical propellant. The program was designed to further explore problems of in-process hazards, system compatibility and stability, and obtaining optimum and reproducible cures. The program included: (1) A comparison of the TVOPA plasticized P-BEP and lower energy polyester binders, (2) scale-up of TVOPA/AlH3 propellants, and (3) an evaluation of difluoroamino binders with HAP. A high impulse TVOPA-AlH3 propellant (VKW) was developed and successfully scaled to 70-lb mixes and 15PC motor firings. The propellant had a delivered impulse (I15 sub 1000) of 267 sec and a density of 0. 0612 lb/cu in. The binder consisted of TVOPA plasticized polyester R-18. The mechanical properties were good, but the in-process hazards are high and the predicted shelf life is low. The propellants based on P-BEP were found to be unstable and, therefore, were not recommended for scale-up past 5PC motors. HAP was determined to be incompatible with the other propellant ingredients and was, therefore, dropped from the program.
