The invention disclosed herein relates to solid propellant formulations, which exhibit good processing properties, good safety characteristics, desirable combustion properties, good safety characteristics and excellent mechanical attributes. The solid propellant formulations disclosed herein burn at a rate of about 0.5 in/s at 1000 psi and show no pressure slope break up to 8000 psi. The solid propellant formulations of the disclosed invention incorporate oxidizers of varying particle size to avoid a pressure slope break. The solid propellant formulation...
1. A solid propellant formulation having a pressure slope break occurring higher than about 2500 psi to 3500 psi comprising: about 6.0 to about 6.5 weight % of at least one polymeric binder with at least one energetic plasticizer; about 25 to about 32 weight % ammonium perchlorate having a particle size of about 10 μm to about 15 μm as a primary oxidizer; about 18 to about 24 weight % ammonium perchlorate having a particle size of about 80 μm to about 100 μm as a secondary oxidizer; about 10 to about 15 weight % of ammonium nitrate having a particl...
