Abstract: The experimental study of the acceleration effects on the interna ballistics performance of solid rocket motor was presented Combustion test was conducted at the AET 3 type high acceleration test stand The aluminized composite solid propellant were tested in unidirectional burning propellant slab motor The experimental results indicate that the average burning rate augmentation ratio a / r 0 of propellant 2010 is as high as 1 515 at 70 g ,the internal ballistics performance of solid rocket motor exhibits a significant change It is useful for design of solid rocket motor

Key words: Solid propellant rocket engine;Acceleration;Aluminized propellant;Interior ballistic performance;Burning rate

摘要： 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
