In order to optimize the design of rocket and increase its firing precision, the simulations and analysis are carried out aiming at the ballistic dissemination of the rolling rocket with empennage under influencing factors. The rigid mathematical model is established to make the simulation after analyze the influence factors, taking rigid ballistic model as example progress simulations and analysis to ballistic dissemination. The results of the simulations show that the factors such as initial disturbance, thrust eccentricity, stochastic wind, aerodynamic eccentricity, mass eccentricity and dynamic misbalance can arouse ballistic dissemination. Meanwhile, the nonlinear motion is another important factor which can arouse ballistic dissemination for the rocket with large value of length divided by diameter.
