摘　　要：为了研究跨介质航行器的水下弹道及相关动力学特性,以某跨介质航行器为研究对象,基于动量定理和动量矩定理建立动力学方程,并对不同速度和空化器倾斜角下的动力学特性进行分析。结果表明:增加初始速度会使航行器水平航行距离和航行深度略微减少,速度下降变快;增加空化器倾斜角亦会导致航行器水平航行距离和航行深度略微减少;减小初始角度对航行器水平航行距离与结束计算时的角度有较大影响,但几乎不影响加速度与受力特性。In order to study the underwater trajectory and related dynamics characteristics of trans-medium vehicles,a trans-medium vehicle was used as the research object.The dynamics equations were established based on the momentum theorem and the moment of momentum theorem,and the dynamics characteristics of the trans-medium vehicle at different velocities and cavitator’s angles were analyzed.The results show that increasing the initial velocity will slightly reduce the horizontal navigation distance and navigation depth of the vehicle,and the velocity will decrease faster;increasing the cavitator’s angle will also lead to a slight decrease in the horizontal navigation distance and navigation depth of the vehicle.Reducing the initial angle has a significant impact on the horizontal navigation distance of the vehicle and the angle at the end of the calculation,but it almost does not affect the acceleration and force characteristics.
