摘要/Abstract

摘要： 研究了低铝含量(5%)的NA(硝胺)/AP/HTPB推进剂高压(15MPa～22MPa)燃烧特性。结果表明:二茂铁衍生物(RMT)能大幅提高推进剂燃速和降低高压燃速压强指数。随着RDX含量(15%～35%)增加,推进剂燃速基本不变;而HMX(15%～30%)含量增加,燃速呈降低趋势。提高配方中RMT含量、细AP的含量或采用RMT/铬酸盐组合催化剂的方法都可将NA/AP/HTPB推进剂高压压强指数降低到0 45以下。

Abstract: The combustion property of Nitramine (NA)/AP/HTPB propellant containing aluminium (5%) is investigated under high pressures (15MPa～22MPa). The results show that ferrocene derivant (RMT) can effectively enhance burn rate of propellants and reduce its pressure exponent under high pressures; The propellant burn rates maintain constant with raising the content of RDX; But burn rates of HMX propellant decrease. The pressure exponent of NA/AP/HTPB propellant is reduced to 0.45 under high pressures by means of raising the content of RMT, the fine particle AP or using RMT/chromic acid salt composite catalysts.
