Abstract:
A solid propellant composition of an oxidizer, a fuel, a binder, and at least one other additive has an improved binder system comprising a non-crystalline polyether having a molecular weight of 1250-9000 (such as Teracol TE and ER-1250/25) and an energetic plasticizer (such as BuNENA, EthylNENA, TEGDN, and DEGDN plasticizers). Propellants of this invention can be used, for example, in ground-launched interceptors, air launched tactical motors, and space boosters.
