Abstract
A solid propellant composition comprising an oxidizer, a fuel and a binder, wherein the binder comprises, based on the weight of the total propellant composition: (a) from about 3 to about 12% of a non-crystalline polyether having a molecular weight of from about 1000 to about 9,000, and (b) from about 1 to about 12% of an inert plasticizer. Propellants of this invention can be used, for example, in ground-launched interceptors, air launched tactical motors, and space boosters.
