Abstract
Abstract The present invention comprises a solid double-base propellant composition comprising on a weight basis from about 5 to about 40 percent of a crystalline substantially non-solvated aluminum hydride, from about 18 to about 39 per cent ammonium perchlorate and from about 30 to about 60 per cent of a plasticized nitrocellulose binder.
