Abstract
Abstract 1. A solid propellant composition consisting essentially of a cured intimate mixture of from about 50 percent to about 80 percent by weight of the total propellant composition of an ammonium salt selected from the group consisting of ammonium chlorate, perchlorate and nitrate and unsaturated polyester resin consisting of the condensation product of saturated polyhydric alcohol and polycarboxylic acid heteropolymerized with an unsaturated compound selected from the group consisting of lower alkenes, lower alkynes, phenyl substituted lower alkenes, lower alkyl dienes, lower alkenyl esters of lower alkanoic acids, lower alkyl esters of lower alkenoic acids, lower alkenyl esters of lower alkenoic acids, allyl diglycol carbonate, diallyl diglycollate, and mixtures thereof; from 0 percent to about 2 percent by weight ammonium dichromate and from about 0.5 percent to about 5 percent by weight of a burning rate acceleration catalyst selected from the group consisting of potassium nitrite, barium nitrite, calcium nitrite and mixtures thereof.
