硝化二乙醇胺对双基推进剂性能的影响

EFFECT OF DINA ON THE PERFORMANCE OF DOUBLE BASE PROPELLANT

吉钠（ＤＩＮＡ）对高氮量硝化棉具有良好的溶解和增塑能力，其爆温比硝化甘油低，比容比硝化甘油大，这时制造高能量、低烧蚀的推进剂极为有利。吉纳应用到双基推进剂中，对推进剂的各种性能均产生了一定的影响，本文针对这些问题进行了粗浅的分析和研究，为推进剂配方研制提供了参考数据。

N-Nitrodihydroxyethyl dinitrate(DINA)is a useful energetic plasticizer indouble base(DB)propellant,which is beneficial to energy increase and ablation reduc-tion.,due to its advantages over nitroglycerin (NG)such as the high capability to solveand plasticize the high nitrogen content nitrocellulose(NC) and larger specific volume. In this paper the effects of these factors on the formulation and properties of DB propel-lant are analyzed and discussed ,and some data would be useful for the research andmanufacture thereof.
