【摘要】 利用密闭爆发器试验研究了大弧厚深钝感球扁药的定容燃烧性能 .揭示了钝感球扁药要达到渐增性燃烧就必须控制钝感层的厚度以及钝感剂在球扁药本体中的浓度梯度分布 .因此必须对钝感过程中钝感剂加入量、钝感时间、钝感方式以及驱溶控挥方法进行优化组合更多还原

【Abstract】 The isovolumetric burning performance of deep deterred oblate spherical powder(DDOSP) with large web is investigated by the closed bomb test. The test results discover the progressivity of burning of DDOSP could be realized if the total deterred layers thickness and the deterrent concentration gradient in the propellant are adjusted well. So deterrent content, deterred time, deterred ways, the methods of desolventizing and controlling volatiles and the other technique parameters should be considered as a whole and optimized to obtain the progressivity of burning of DDOSP.更多还原
