The Oblique Water Entry Impact of a Torpedo and Its Ballistic Trajectory Simulation

摘要：

The torpedo water entry impact has a great effect on its underwater ballistic trajectory. In the paper, by wind tunnel experiments we get the torpedo water entry drag coefficient, amending it with supercavitation continuous factor and local cavity effect factor, and then the torpedo motion equation is established. Finally, the large scale nonlinear finite element software MSC.dytran is used to simulate the initial water entry impact of a Disk
