Abstract
A slurry casting process is described capable of produ
cing crosslinked double base propellant having improved burn
ing rates and high specific impulse. Such propellants can be
formulated to be smokeless. Improved burning rates are
achieved by incorporating into a slurry of double base compo
sition, casting powder granules containing 20% to 75% by
weight of small particle ammonium perchlorate. The casting
powder granules substantially retain their identity in the cured
propellant matrix. The casting powder granules have a high
burning rate and are uniformly distributed throughout the
propellant. The granules are responsible for increasing the
burning rate of the entire crosslinked double base propellant
composition of the invention.
