Composite solid propellant with a pulverulent metal/oxidizer agglomerate base

摘要

A composite solid propellant with a stable burning rate comprising ammonium perchlorate, a binder system of telomeric polybutadiene or copolymers of butadiene and acrylonitrile with terminal functional groups or functional groups distributed statistically along the chain, which are hardened by means of corresponding hardeners into rubber-elastic binders, finely pulverized, readily oxidizable metals and, optionally, inorganic fluorides, plasticizers and burning rate moderators, wherein ammonium perchlorate together with one or more of said finely pulverized metals, as well as, optionally, said inorganic fluorides are present as an agglomerate of larger particles having a particle size of between 100 m and 2,000 m.
