摘　　要：利用现代燃烧诊断技术对ＰＮＴＯＧＡＰ推进剂中的ＰＮＴＯ的催化特性进行了探讨，认为ＰＮＴＯ的催化机理与普通铅盐明显不同。ＰＮＴＯ是燃烧反应中心，它加速了ＧＡＰ推进剂的燃烧，其作用部位在凝聚相。单独使用ＰＮＴＯ可使ＲＤＸ／ＧＡＰ／ＮＧ推进剂的燃速压力指数降低至０．５左右。The catalysis mechanism of Pb NTO salt (PNTO) in GAP propellant combustion was investigated by means of modern diagnostics.It is found the catalysis mechanism of PNTO is quite different from that of the common Pb salt.PNTO is the burning centre,the combustion of the propellant is speeded up at the site where PNTO is situated.At the presence of PNTO as a single catalyst,the combustion rate pressure exponent of RDX/GAP/NG propellant decreases to the level of about 0.5.
