Effect of Rocket Firing Pattern

Abstract

The vibration of Rocket launched platform causing the aiming direction change. To minimize the vibration effect, the firing sequence to vibrate structure was considered. In this study, the model was defined as flexible body motion while subjected to load. The force generated while the rocket moves along the launched tube make the tube deformed and vibrated. This deformation was measured and transform into Gain-Frequency domain. The study results show the pattern of firing as Leap-Frog Scheme in every row of rocket housing and for overall the rocket pattern was recommended as zig-zag to minimize vibration on structure.
