摘　　要：利用推进剂配方理论计算程序,计算了Bu NENA钝感交联改性双基推进剂的能量性能。结果表明,标准理论比冲随粘合剂GAP/NC比例和增塑比的变化很小;随固体含量、固体填料RDX/AP/Al配比的变化很大。CL-20取代AP后,Bu NENA推进剂在固体含量为70%,其中CL-20为39%~52%范围内（相应的Al粉含量在7%~10%范围）,都可得到2700N·s/kg以上的理论比冲值,是一个有潜力的集高能、钝感、低特征信号于一身的推进剂体系。The energy properties of insensitive and cross-linked Bu NENA propellant were calculated by propellant energy calculation program.The calculation results show that the standard theoretical specific impulse is affected slightly by the ratio of GAP / NC and the ratio of plasticizer / binder,while the content of solids and the ratio of RDX / AP / Al have great effect. Replaced AP with CL-20,Bu NENA propellant has a high value of specific impulse over 2700N·s / kg in very wide scope when the content of solids is 70% and the content of CL-20 is 39% ~ 52%（ corresponding content of Al is 7% ~ 10%）.The results show that Bu NENA propellant is a prominent propellant with high energy,insensitiveness and low characteristic signal.
