【摘要】 为了研究RDX和硝基胍(NGu)对硝胺发射药在低压下燃烧性能的影响,对六种RDX/NGu配比不同的硝胺发射药进行低压密闭爆发器静态燃烧实验,获得了在20~60MPa压力范围内硝胺发射药的燃烧试验数据。结果发现:硝胺发射药在测试压力范围内有燃速压力曲线转折现象,并且NGu对低压下硝胺发射药燃烧规律有很好的调节作用。更多还原

【Abstract】 The effects of the content of Hexogen(RDX)and Nitroguanidine(NGu) on the combustion behavior of nitramine propellants under low pressure were studied in the closed bomb.The combustion data of six kind of nitramine propellants with different ratio of RDX /NGu were obtained from 20 MPa to 60 MPa by the closed bomb test.The results indicate that there is a change of burning rate pressure exponential of nitramine propellants,and the content of NGu can adjust the combustion rules of nitramine propellants under low pressure.更多还原
