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

摘要

The burning rates of five nonmetallized composite propellantswere measured in acceleration fields up to 1000g using a combustionbomb mounted on a centrifuge. Two propellants were burned at 1000psia and all five were burned at 500 psia. The experimental results were examined to separate the effects ofpressure, base burning rate and AP crystal size on burning rateaugmentation. Increasing pressure was found to increase the augmentationexcept at low acceleration levels. The augmentation was foundto be a strong function of base burning rate and a weak function ofAP crystal size.
