摘要:
采用X射线单晶衍射表征了新型18-冠-6/二硝酰胺铵含能共晶(18-Crown-6/ADN)氧化剂晶体的结构;采用氧弹式量热计测定了其燃烧热并获得其标准摩尔生成焓(ΔfHmθ);采用最小自由能法计算了18-Crown-6/ADN对3,3-二叠氮甲基氧丁环与四氢呋喃共聚醚(BAMO-THF)推进剂能量性能的影响。结果表明,18-Crown-6/ADN晶体属于单斜晶系,C2/c空间群,晶胞参数:a=2.393 5 nm、b=0.863 27 nm、c=2.032 4 nm;α=90°、β=112.874°、γ=90°;18-Crown-6/AND的ΔfHmθ为-(833.57±4.89) kJ/mol,其取代配方中的AP、HMX、ADN或CL-20后推进剂的理论比冲(Isp)最低;含18-Crown-6/ADN的BAMO-THF推进剂中加入部分高能组分(如CL-20、HMX)可提高其能量性能;能量计算表明,BAMO-THF/A3、Al、AP、(18-Crown-6/ADN)/CL-20/HMX的质量分数分别为25%、18%、15%、42%,18-Crown-6/ADN、CL-20和HMX的质量比约3∶4∶3时,配方的Isp约2 550 N·s/kg,燃烧室温度约2 900 K,燃气平均相对分子质量约24.50,特征速度约1 540 m/s。
Abstract:
The crystal structure of 18-Crown-6/ammonium dinitramide (18-Crown-6/ADN) energetic cocrystal oxidizer was characterized by single crystal X-ray diffraction. Its heat of combustion was measured by an oxygen bomb calorimeter. And the standard molar enthalpy of formation (ΔfHmθ) was also obtained by the heat of combustion. The effect of 18-Crown-6/ADN on the energy characteristics of 3,3-bis(azidomethyl) oxetane and tetrahydrofuran copolymer (BAMO-THF) based propellant was calculated by the least free energy method. The results show that the 18-Crown-6/ADN crystal belongss to monoclinic system, space group C2/c with crystal parameters of a=2.393 5 nm, b=0.863 27 nm, c=2.032 4 nm, α=90°, β=112.874°, γ=90°. Its ΔfHmθ is -(833.57±4.89) kJ/mol. The theoretical specific impulse (Isp) is the lowest when the AP, HMX, ADN or CL-20 in the formula is substituted by the 18-Crown-6/ADN. It can improve the energy performance of BAMO-THF propellant containing 18-Crown-6/ADN by adding some high-energy components. The energy calculation results show that the Isp is about 2 550 N·s/kg, the combustor temperature is about 2 900 K, the average relative molecular mass of combustion gas is about 24.50 and the characteristic velocity is about 1 540 m/s when the content of BAMO-THF/A3, Al, AP, (18-Crown-6/ADN)/CL-20/HMX is 25%, 18%, 15%, 42% and the mass ratio of 18-Crown-6/ADN, CL-20 and HMX is about 3:4:3.
