入水参数对“水漂式”航行体跨介质运动影响数值仿真分析

Analysis of Influence of Water Entry Parameters on Cross- Medium Movement of “Water Drift” Aerial-Aquatic Vehicle

以"水漂式"跨介质航行体为背景,采用AUTODYN软件建立了不同入水角度,不同入水速度的"水漂式"跨介质航行体的入水模型,通过对数值仿真结果的分析,得到了入水角度、入水速度对出水角度、运动速度及运动轨迹的影响。有效地验证了该"水漂式"航行体功能实现的可能性。结果表明,在同一入水速度下,随着入水角度的增加,出水角增大;在同一入水角度下,随着入水速度的增加,出水角增大。

Based on the"water drift"aerial-aquatic vehicle,this paper used AUTODYN to establish the water entry model of the"water drift"aerial-aquatic vehicle with different water entry angles and speeds.Through the analysis,the influence of the water entry angle,the water entry speed on the water outlet angle,the speed and the trajectory were obtained.These results effectively verified the possibility of the realization of the"water drift"warhead function.The results show that with the same water entry speed,the vehicle’s water outlet angle increases with the increase of the water entry angle,and with the same water entry angle,the vehicle’s water outlet angle increases with the increase of water entry velocity.
