摘要
研究了超高燃速推进剂的侧面限燃包覆。通过包覆层厚度、中止燃烧、间接证明实验,证实了采用硬质PVC黏合剂为内层,添加石棉粉的醋酸纤维素为外层的包覆层,可以使超高燃速推进剂侧面不发生窜火,达到稳定对流燃烧,燃速可达1000mm/s以上。
A novel propellant, which was of porous structure and had very high burning rate (above 1 000 mm/s), was prepared. Its inhibitor is very important in studying the application of very high burning-rate propellant. The propellant grains with size Φ 25×25 mm were inhibited using polyvinyl chloride (PVC) as inner layer and cellulose acetate added flake asbestos as outer layer. The experiment of determining the thickness of coating layer, termination burning and indirect proof were studied. Results show that the convection burning of VHBR propellant is stable, no flame-leak. Its burning rate is above 1 000 mm/s by using this way.
