Abstract:
A solid propellant formulation comprising:from about 25% to about 55% by weight ammonium perchlorate particles having an average size of about 200 .mu.m;from about 25% to about 40% by weight ammonium perchlorate particles having an average size in a range of from about 2 .mu.m to about 50 .mu.m;from about 7% to about 15% by weight of at least one energetic polymeric binder, which further comprises a polymeric binder and an energetic plasticizer; andfrom about 1% to about 4% by weight of at least one ballistic modifier;wherein said propellant formulation has a burn rate slope of less than about 0.15 ips/psi over a substantial portion of a pressure range of from about 1,000 psi to about 7,000 psi and a temperature sensitivity of less than about 0.15%/.degree. F.,wherein said burn rate slope is equal to: ##EQU5##
