根据最小自由能法，采用 NASA-CEA软件，研究了六种硝基呋咱化合物：3-硝基呋咱（ NF）、3，4-二硝基呋咱（ DNF）、3-硝氨基-4-硝基呋咱（NNF）、3-硝氨基-4-硝基呋咱铵盐（ANNF）、3-硝氨基-4-硝基呋咱肼盐（HNNF）和3-硝氨基-4-硝基呋咱羟胺盐（HANNF）的能量特性。研究了硝基呋咱化合物含量对复合改性双基（CMDB）推进剂能量特性的影响和压强对硝基呋咱／CMDB推进剂能量特性的影响。结果表明，HANNF和HNNF单元推进剂的比冲高于RDX，分别为2744．8 N·s·kg－1和2802．2 N·s·kg－1。六种硝基呋咱化合物使 CMDB推进剂的比冲大幅提高，其中 HNNF 和 HANNF 使 CMDB 推进剂的比冲分别提高74．6 N·s·kg－1和91 N·s·kg－1。六种硝基呋咱／CMDB推进剂的比冲均随压强升高而增加。比冲受压强影响顺序为DNF＞NNF＞HANNF＞ANNF＞HNNF＞NF。

Based on the minimum free energy method,the energy characteristics of six nitrofurazan compounds,3-nitrofurazan (NF),3,4-dinitrofurazan(DNF),3-nitrimino-4-nitrofurazan(NNF),3-nitramino-4-nitrofurazan ammonium salt(ANNF),3-niti-mino-4-nitrofurazan hydrazonium salt( HNNF)and 3-nitramino-4-nitrofurazan hydroxyl ammonium( HANNF),were studied by NASA- CEA software. Effects of the content of nitrofurazan compounds on the energy characteristics of CMDB propellants and effects of pressure on the energy characteristics of nitrofurazan /CMDB propellants were studied. Results show that the specific impulses of HANNF and HNNF monopropellants are 2744. 8 N·s·kg-1 and 2802. 2 N·s·kg-1 ,respectively,which are obviously higher than that of RDX. Six nitrofurazan compounds make the specific impulse of CMDB propellants increase substantially,in which HNNF and HANNF make the specific impulse of CMDB propellants increase by 74.6 N·s·kg-1 and 91 N·s·kg-1,respectively. The specific impulse for the six propellants increases with the increase of pressure. The order affecting the specific impulse by pres-sure is DNF>NNF>HANNF>ANNF>HNNF>NF.
