摘要:
子母弹在抛撒内弹道过程结束时子弹产生的翻转运动对抛撒有效性影响很大,为研究子弹翻转角速度的形成机理和控制规律,对中心燃气式抛撒内弹道过程进行了两相流建模和仿真计算。通过仿真结果与实验结果的对比验证了模型的可行性。设计了一种置于燃气流场中的扰流板,得到了子弹翻转角速度随扰流板径向位置增大而单调递减的变化规律,揭示了流场中涡旋及其伴生的负压区对子弹翻转角速度的影响机理,研究成果可以为子母弹抛撒系统的设计和改进提供理论基础。
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.
