Abstract
This invention teaches preparation of individual and uncoated propellant grains by incorporating a coating or integral layer of ignition compound, specifically simple salts of decahydrodecaboric acid and coprecipitates of these salts with an oxidizer. The resulting propellant grains so prepared exhibit substantially improved ignition capability, virtually independent of ambient conditioning temperature conditions at the time of use.
