摘　　要：通过密闭爆发器、高压熄火装置、扫描电子显微镜(SEM)以及发射药理化性能检测技术,研究密度和冲击强度对含能热塑性弹性体(ETPE)发射药燃烧特性的影响。结果表明,BAMO/AMMO基ETPE发射药的实测密度大于理论密度的84%时,密度对燃烧特性影响明显,密度增加,燃烧速度、燃速系数和压力指数降低;冲击强度与燃烧速度和燃速压力指数呈一定负相关性。The effects of density and impact intensity on combustion properties of energetic thermoplastic elastomer（ETPE） gun propellants were studied by closed bomb test,high pressure flameout set,scanning electron microscopy（SEM） and physicochemical property test.The results show when the actual density of ETPE gun propellant（BAMO/AMMO based） is 84% more than that of theoretical density,with increase of the density,the burning rate,burning-rate coefficients and pressure exponent of ETPE gun propellants reduce.There is a adverse correlation between the impact intensity and the burning rate and pressure exponent of ETPE gun propellants.
