摘　　要：利用最小自由能法,在标准条件(燃烧室压力pc:喷管出口处压力pe=70∶1)下,计算了含5-氨基-四唑硝酸盐(5-ATEZN)推进剂的能量特性。结果表明,5-ATEZN单元推进剂的比冲为2371.38 N·s·kg-1,与黑索今(RDX)及奥克托今(HMX)单元推进剂接近,且5-ATEZN的氧平衡(-10.8%)远高于RDX及HMX。用5-ATEZN取代粘合剂端羟基聚丁二烯(HTPB)推进剂中的高氯酸铵(AP)和RDX时,推进剂比冲和特征速度均降低;而用5-ATEZN取代GAP推进剂中的AP时,推进剂比冲和特征速度随5-ATEZN含量增多呈抛物线形变化,最高比冲可达2580.62 N·s·kg-1,与原配方相比提高17.93 N·s·kg-1。同时由于5-ATEZN不含氯元素,对降低推进剂的特征信号十分有利。因此,用5-ATEZN取代适量AP是实现GAP(聚叠氮缩水甘油醚)推进剂高能化和少烟化的一个可行途径。Under standard condition（chamber pressure p_c：nozzle exit pressure p_e =70：1）,the energy characteristic parameters of solid propellant containing 5-amino-tetrazolium nitrate（5-ATEZN）,a novel kind of high energy compounds with high nitrogen content,were calculated by the least free energy method.Results show that specific impulse of 5-ATEZN monopropellant is 2371.38 N · s · kg^-1,which is similar to that of RDX and HMX monopropellant.Moreover,the oxygen balance of 5-ATEZN（-10.8%） is much higher than that of RDX and HMX.Specific impulse and characteristic velocity of HTPB propellant decrease with substituting 5-ATEZN for the ingredient AP or RDX.But for GAP propellant,specific impulse and characteristic velocity are characterized by a parabola with substituting 5-ATEZN for the ingredient AP.The maximum specific impulse can reach 2580.62 N · s · kg^-1,which is 17.93 N ？ s ？ kg^-1higher than that of previous formula without 5-ATEZN.Since 5-ATEZN has no chlorine,it＇ s helpful to reduce the characteristic signal of propellant.Therefore,substituting 5-ATEZN for the ingredient AP appropriately is a feasible approach to achieve the target of higher-energy and less-smoke for GAP propellant.
