摘要：
According to ballistic characteristics, bomb-parachute system was simplified and calculation model of trajectory stability was established. Based on the model, effect of related factors and sensitive degree of these factors on trajectory stability was analyzed and compared. The results indicate that equatorial damping coefficient, equatorial rotational inertia and drag coefficient of parachute are key influence factors of trajectory stability. In addition, extending flight distance before parachute opening can speed up convergence rate of attack angle and the trajectory stability will be better correspondingly. The results could provide references not only for the research of optimal design of bomb-parachute system, but also the further analysis of trajectory stability.
