In order to attain variation law of flexible deformation, deformation degree and stress distribution after rocket deformation during free flight of rocket with large length/diameter ratio, ANSYS software was used for grid design, aerodynamic calculation and structure calculation, then the numerical method of fluid-structure interaction (FSI) was used for analysis on the free flight rocket with different Mach number in this paper, then the rocket's deformation and stress distribution were obtained with the ANSYS. This result can provide theoretical basis for the design and research of rocket with large/diameter ratio.
