A slurry casting process is described capable of producing crosslinked double base propellant having improved burning 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 composition, 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.
描述了一种能够生产交联双基推进剂的浆料浇注工艺,这种推进剂具有更好的燃烧速率和更高的比冲。这种推进剂可以配制成无烟推进剂,通过将含有 20% 至 75% (按重量计)小颗粒
高氯酸铵的铸造粉颗粒加入双基组合物的浆料中,可以提高燃烧速率。浇注粉颗粒在固化的推进剂基质中基本保持其特性。铸造粉颗粒的燃烧率很高,并均匀地分布在整个推进剂中。这些颗粒可提高本发明整个交联双基推进剂组合物的燃烧速率。
