含BuNENA钝感交联改性双基推进剂能量分析

摘要

The energy properties of insensitive and cross⁃linked BuNENA propellant were calculated by propellant energy calcu⁃lation 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,BuNENA propellant has a high value of specific impulse over 2 700 N·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 BuNENA propellant is a prominent propellant with high energy,insensitiveness and low characteristic signal.%利用推进剂配方理论计算程序，计算了BuNENA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， BuNENA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2700 N·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。
