摘要
研究新型氧化剂1-氨基-1,2,3-三唑硝酸盐(ATZ-NO3)的引入对各类固体推进剂能量特性的影响.利用国军标方法GJB/84-96及推进剂能量特性计算与CAD系统软件,在标准条件(Pc/Pe=70∶1)下,计算了含1-氨基-1,2,3-三唑硝酸盐(ATZ-NO3)推进剂的能量特性.结果表明,ATZ-NO3单元推进剂的比冲为2 413.96N·s·kg-1,远高于AP单元推进剂,与RDX及HMX单元推进剂接近.用ATZ-NO3取代HTPB推进剂中的AP和RDX时,推进剂比冲和特征速度均降低;而用ATZ-NO3取代GAP推进剂中的AP时,推进剂比冲和特征速度随ATZ-NO3质量分数多呈抛物线形变化,最高比冲可达2 608.50N·s·kg-1,固体填料存在最佳添加比.同时由于ATZ-NO3不含氯元素,因此将ATZ-NO3引入GAP推进剂对提高GAP推进剂的综合性能是有益的.
Under the standard condition（Pc/Pe=70∶1）,the energy characteristic parameters of the solid propellant containing 1-amino-1,2,3-triazolium nitrate（ATZ-NO3）were calculated by GJB/84-96 and CAD system of propellant energy calculation using the minimum free energy method.The result shows that specific impulse of ATZ-NO3 monopropellant is 2 413.96N·s·kg^-1,which is much higher than that of AP monopropellant and similar to that of RDX and HMX monopropellant.Specific impulse and characteristic velocity of HTPB propellant decrease with ATZ-NO3 substituting the ingredient AP or RDX.But for GAP propellant,specific impulse and characteristic velocity were characterized by parabolas with the increasing of ATZ-NO3 content by substituting the ingredient AP.The maximum specific impulse can reach 2608.50N·s·kg^-1and there exists optimum content ratio of solid fillers.Meanwhile ATZ-NO3 has no chlorine,therefore,ATZ-NO3 introduced into propellant composition is helpful for the comprehensive performance of GAP propellant.
