Abstract

A family of high performance, space motor, solid propellants based on polyglycidyl nitrate elastomer binder, ammonium perchlorate oxidizer and beryllium or beryllium hydride fuel which do not require the presence of plasticizers. A high performance, space motor, solid propellant based on a polyglycidyl nitrate elastomer binder, ammonium perchlorate or hydroxy ammonium perchlorate and beryllium or beryllium hydride optimizes performance at low solids levels.
