This paper deals with fully integrated computational simulations to examine the non-linear feedback interaction between fluid, structure, and burning modules inside a solid rocket motor. Various methods are used for simulating the interior of the solid rocket motor. The Arbitrary Lagrangian-Eulerian (ALE) description and mesh moving method are employed to efficiently track the burning process along a grain surface. An automatic remeshing algorithm is added to the fluid, structure, and burning process to accurately analyze unsteady fluid-structure-burning coupling phenomena with deforming propellant grain during the simulation. The common-refinement method is implemented to obtain numerically accurate and physically conservative data transfers across the interface meshes between fluid and structure domain. Conventional serial-staggered scheme is adopted to efficiently integrate each module. The developed solver is then applied to the full-burning simulation of the axisymmetric solid rocket motor, Attitude Control Motor (ACM). The computed pressure-history inside the rocket motor shows the same tendency with experimental data in overall burning process.
