This paper analyzes the dominating factors that influence damping ballistic coefficient of one dimension trajectory correction fuze, brings forward that it is a precondition of optimize and simulation for damping ballistic coefficient to work out the time of calculating ballistic trajectory and the distance of maximum range correction. The distance of maximum range correction is associated with the time of calculating ballistic trajectory. Based on shooting parameter error, range error before correction and range error after correction, the basic formula of calculating expanded range and the distance of maximum range correction is settled. Based on the method of getting the optimal damping ballistic coefficient, a flow chart of simulation program of damping ballistic coefficient is showed, and the result of simulation for a kind of projectile is listed.
