Abstract

In order to completely perform the mission, It is significant to study the trajectory of projectiles, e.g. Unmanned Underwater Vehicle (UUV) in the process of submarine launch. Three dimensional numerical model is established based on the volume of fluid (VOF) method in combination with the realizable viscous model, open channel model, and dynamic grid technology. Six degrees of freedom (6DOF) trajectory were realized quantitatively in the simulation process under three cases, including that static flow and water flow with constant velocity and various velocity. At the same time, the pressure field is analyzed in the whole launch process. It concludes that the pressure field only changes around the UUV’s head cap and tail part. The influences of constant velocity on dynamic characteristics of UUV are different from various velocity. Water velocity is no negligible impact factor which decide whether the UUV launch successfully.
