초록

Propellant grain consisting essentially of: A. from about 50% to about 75% by weight of an oxidizer consisting essentially of ammonium nitrate; B. from about 1% to about 20% by weight of a cured polymeric binder; C. from 0% to about 30% by weight of a nitrate ester plasticizer; D. from about 3.5% to about 8% by weight of boron in free elemental form; and E. from 0% to about 3% by weight of aluminum metal. The grain has a pressure exponent not exceeding about 0.30 at a combustion pressure between about 2500 and about 7000 pounds per square inch (between a...
