Abstract

Abstract

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.
