| Abstract: | This paper investigates the dynamic behavior on a flexible spin rocket launching system having a clearance. The attitude,binding forces and frictions of the spinning rocket are described, based upon the varying contact stiffness and relative deformation traversed between the rocket and the launcher. Dynamic responses are obtained via the numerical method,and influence of the clearance between the rocket and launcher on rocket's motion attitude and binding forces are analyzed. |

| Keywords: | mechanics rocket dynamics clearance between the rocket and launcher launch behavior |
