摘要
Abstract
The submunition overturning movement greatly affects the effectiveness of dispersal at the end of the dispersing interior ballistic process. To study the forming mechanization and the controlling regulations of the submunition overturning angular rate, the central gas dispersing interior ballistic process is modeled and simulated in two phases. The feasibility of the model is proved by the comparison of numerical simulation results and test results. The regulation is obtained that the angular rate of submunition overturning monotonically decreases while the spoiler radial position increases. The spoiler in flow fields is designed. The research results reveale a mechanization of how both of the vortex in flow fields and the generated negative pressure zone influence the submunition overturning angular rate. The final results provide a theoretical basis for improving the submunition dispersing system.关键词
