Abstract

Abstract

To investigate the water-entry process of an airborne torpedo, the forces encountered by the water-entry airborne torpedo were analyzed and calculated by using MATLAB.A finite element model for the torpedo entry into water was established by using the finite element code MSC/DYTRAN.Thereby, by considering different water-entry angles and velocities, the impact forces encountered by the water-entry torpedoes were calculated as well as their corresponding pressure at the surfaces of the torpedoes for the torpedoes with different warhead shapes.The effects of water-entry angles, velocities and warhead shapes were analyzed on the maximum force and the peak pressure encountered by the water-entry torpedoes.And the water-entry trajectories of the torpedoes were discussed.The investigated results are helpful for forecasting the impact forces of water entry about the torpedoes.
