含呋咱衍生物富燃料推进剂的能量性能

摘要

Furazan is a kind of novel high energy material and has a good future application in propellants and explosives. This work studies the energy properties of Al/Mg/HTPB/AP fuel-rich propellants comprising furazan derivatives. The results reveal that the specific impulse (Is) of propellant comprising DAAzF is the largest with propellant comprising CL-20 at the same mass fraction(w). The mean relative molecular mass(Mg) of propellants comprising furazans is about 29, the flame temperature in after-burning chamber(Tc) is about 2200K, and the values of (-M)g and Tc increase with increasing the mass fraction of furazans.%采用最小自由能法,研究了含呋咱衍生物的Al/Mg/HTPB/AP富燃料推进剂的能量性能,结果表明,随着呋咱衍生物含量的增加,富燃料推进剂比冲明显增加,其中含质量分数为25%的DAAzF(4,4'-二氨基-3,3'-偶氮呋咱)的富燃料推进剂比冲可达7 522.9 N·s·kg-1,比相同质量含量下含CL-20富燃料推进剂比冲高260N·s·kg-1.含呋咱衍生物富燃料推进剂气相平均相对分子质量((-M)g)约为29,补燃室火焰温度(Tc)约为2 200K,且二者随着呋咱衍生物含量增加而略有增加.
