用片型装药火箭发动机和含铝复合推进剂 ,研究了加速度对固体火箭发动机内弹道性能的影响。研究结果表明 ,在加速度 70 g的条件下 ,2 0 1 0推进剂的平均效应燃速比 ra/ r0 高达 1 .51 5,固体火箭发动机的内弹道性能呈现明显的变化。该项研究对发动机设计有实际意义 The effect of acceleration on the internal ballistic performance of solid rocket motor was studied by using patch propellant rocket motor and aluminum-containing composite propellant. The results show that under the condition of acceleration of 70 g, the average effect combustion rate of propellant 210 r / a is as high as 1.551, and the internal ballistic performance of solid propellant rocket engine shows obvious changes. This research has practical implications for engine design
