Abstract

Ballistic modifiers are chemicals, that when added to a propellent, alter the magnitude of the burn rate and the rate of burn over a series of pressures (slope). Often very little, less than one tenth of one percent, needs to be added to the propellent formulation to accomplish this. Limited studies of how and why ballistic modifiers work have been previously conducted. Certain chemicals were known to have certain effects. For the purpose of this study, two hypotheses were evolved and investigated--either cation charge or cation size caused the changes in the burn rate and slope of a propellant. The results of this study will be used in an upcoming project at the Astronautics Laboratory. (JES)
