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

| Summary: | 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. |
