초록

A family of high performance, large launch vehicle, solid propellants based on polyglycidyl nitrate elastomer binders. A clean, large launch vehicle, solid propellant based on a polyglycidyl nitrate elastomer binder, ammonium nitrate oxidizer and aluminum or magnesium fuel optimizes at low solids levels and produces essentially no HCl or chloride ion in the exhaust.
