The Effects of Acceleration on Burning Rates of Nonmetallized Composite Propellants.

Abstract

The burning rates of five nonmetallized composite propellants were measured in acceleration fields up to 1000g using a combustion bomb mounted on a centrifuge. Two propellants were burned at 1000 psia and all five were burned at 500 psia. The experimental results were examined to separate the effects of pressure, base burning rate and AP crystal size on burning rate augmentation. Increasing pressure was found to increase the augmentation except at low acceleration levels. The augmentation was found to be a strong function of base burning rate and a weak function of AP crystal size. The results were compared with Sturm's model for augmentation of nonmetallized composite propellants and found to compare favorably. A new expression for d-critical was proposed which better correlates experimental data. (Author)
