【摘要】 报道了纳米/微米复合粒子对固体推进剂的燃烧性能、力学性能、热机感度及工艺性能等的影响。研究结果表明,当纳米/微米粒子选择合适、工艺条件适当时,纳米/微米复合粒子与单一纳米或微米粒子相比可使推进剂的燃烧性能、力学性能及工艺性能都有明显提高,并可使推进剂的热机感度明显降低。更多还原

【Abstract】 In this paper, the influence of combustion property, mechanics property, heat-mech sensitivity and process parameters are reported after nano/micro composite particles were used in solid propellant. The results showed that through the use of nano/micro composite particles in solid propellant and suitable handling of process, the composite particles were better than nano-particles or micro-particles in improving the propellant’s combustion property, mechanic property and process parameters, and the key point is that the propeliant’s mechanical sensitivity was obviously decreased.更多还原
