Abstract
A solid rocket propellant composition comprising a major amount of ammonium perchlorate, a minor amount of aluminum powder, a minor amount of a binder, and an effective, burn rate modifying amount of Guignet's green pigment or oxidized Guignet's green. Guignet's green pigment increases the burn rate of the propellant without unacceptably increasing the pressure dependence of the burn rate.
