| 摘 要： | 研究了7种铅盐(PCDS、PDS、NIP、NTO铅、2,4-二羟基苯甲酸铅、苯二甲酸铅、碳酸铅)对高能无烟改性双基推进剂燃烧性能的影响。结果表明,铅盐的燃烧催化作用可能与铅盐的分子结构有关,上述铅盐中PCDS对高能无烟改性双基推进剂的燃烧催化效果最好;铅盐和炭黑复配体系可提高推进剂燃速,并降低压强指数。

| Abstract: | The effects of seven lead salts, including PCDS, PDS, NIP, lead 3-nitro-1,2,4-triazol -5-one, lead 2,4-dihydroxybenzoate, lead phthalate and lead carbonate, on the combustion characteristics of the high energy smokeless modified double-base propellant(HESMDB) was studied in details. The results show that the catalyzed combustion of lead salts relates to the molecular structure of the lead salts. PCDS has the best catalytic effect on the combustions of the HESMDB. Whereas the mixtures of lead salts and carbon black used in the HESMDB, enhance the burning rate of the propellants at low pressure and decrease the pressure exponent of propellant. |
