Abstract:

研究了包括3,3′-二硝基-4,4′-氧化偶氮呋咱(DNOAF)、N,N′-二(硝基呋咱基)草酰胺DNFOA和5,5′-二(叠氮甲基)-3,3′-联异呋咱(DABIF)的一系列二呋咱化合物的性能。其中,DABIF和DNFOA的特性落高分别为(68±3)cm和82cm(H50,5kg落锤),可望作为不敏感炸药应用。根据Kamlet方程计算得到DNFOA的理论爆速D=8560m·s-1,爆压pCJ=33.6GPa,DNOAF的理论爆速D=9390m·s-1,爆压pCJ=40.5GPa。按照以20%呋咱含能化合物代替某NEPE推进剂,计算表明,DNOAF基推进剂的比冲为269.1s-1,高于HMX基NEPE推进剂的比冲268.6s-1,可知DNOAF爆轰性能优良。
