Abstract
Abstract 1. A solid propellant composition comprising: from 60 to 90 weight per cent of an oxidizer component selected from the group of solid inorganic oxidizing salts consisting of ammonium perchlorate, the alkali metal perchlorates, ammonium nitrate, the alkali metal nitrates, and mixtures thereof, at least a major portion of said oxidizer component being at least one of said perchlorates; from 10 to 40 weight per cent of a binder component comprised of a rubbery material selected from the group consisting of natural rubber, synthetic rubber polymers, and mixtures thereof; and from 0.1 to 8 weight per cent of a burning rate depressing agent selected from the group consisting of ammonium fluoborate, hydrazine dihydrochloride, barium periodate, and ferric oxalate.
