摘　　要：从物理化学性能、安全性能、燃烧性能和内弹道性能四个方面对含六硝基六氮杂异伍兹烷(CL-20)的改性双基推进剂(CMDB)——CL-20/CMDB进行了研究。燃烧性能的测试表明,在6～20 MPa下,CL-20/CMDB较RDX/CMDB推进剂的燃速高2.5～8.94 mm·s-1,其压强指数为0.28(10～20 MPa);物理化学性能测试表明,与RDX/CMDB推进剂相比,CL-20/CMDB推进剂具有更高的密度、爆热和比容,其密度、爆热和比容分别为1.76 g·cm-3、5034 J·g-1和658 L·kg-1;安全性能测试表明,CL-20/CMDB与RDX/CMDB推进剂相比,其化学安定性相当,撞击感度较低,但摩擦感度较高,达到了100%。内弹道性能测试表明,CL-20/CMDB推进剂在Φ36发动机中的比冲可以达到2226.1 N·s·kg-1(227 s),比RDX/CMDB推进剂的比冲高15.1～39.4 N·s·kg-1。The physic-chemical properties,safety properties,combustion properties and inner ballistic properties of composite modified double-based propellant containing hexanitrohexaazaisowurtzitane（CL-20）（CL-20/CMDB） propellants were studied.Results show that the burning rate of CL-20/CMDB propellant is 2.5～8.94 mm·s-1 higher than that of RDX/CMDB propellant at 6～20 MPa.The pressure exponent of CL-20/CMDB propellant is greater,which is up to 0.28 at 10～20 MPa.CL-20/CMDB propellant has higher density,explosion heat and specific volume than that of RDX/CMDB propellant.The density,explosion heat and specific volume of CL-20/CMDB propellant is 1.76 g·cm-3,5034 J·g-1 and 658 L·kg-1,respectively.CL-20/CMDB propellant has the same chemical stability as RDX/CMDB propellant,lower impact sensitivity than RDX/CMDB propellant,but higher friction sensitivity,up to 100%;the specific impulse of CL-20/CMDB propellant can achieve 2226.1 N·s·kg-1（227 s） in Φ36 rocket motor.
