Molecular sieve containing stabilization system for urethane - crosslinked double base propellant

Abstract

A dual stabilization system for urethane - crosslinked double base propelt. The stabilization system includes N-Methyl-p-Nitroaniline and Aluminum Silicate molecular sieve. The two stabilizers function in a complementary fashion wherein the N-Methyl-p-Nitroaniline reacts with and makes harmless the nitrogen (III) oxide during the propellant aging process. The Aluminum Silicate molecular sieve is selected to have a pore size of more than about 10 angstroms and reacts with and makes harmless the nitrogen (V) oxides, primarily nitric acid, during the propellant aging process.
