The model and simulation of the cluster submunition rollover movement

In order to explore on the rollover movement rule of the submunition during the process of the interior and external ballistic trajectory, this paper takes a certain cluster muniiton as the research object to analyze the process of the interior and external ballistic trajectory, and established the interior ballistic rollover movement mathematical model of the submunition with center tube dispersing. Perform the simulation to obtain the rollover angular velocity and angular displacement at end of the process of the interior ballistic trajectory. The external ballistic rollover movement models of the submunition before and after the stability ribbon spreading out are established, and the simulation analysis of the rollover movement process is made. Then the rollover movement law of the submunition external ballistic can be got.
