| 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 |
