Research on the effect of head type on the hydrodynamics of vertical motion vehicle launched by gas curtain

摘要：

　　The numerical simulation was used to research the effect of different head vehicles on gas curtain and hydrodynamics in the process of underwater exiting tube and movement in water and exiting water under gas curtain launch.The two different heads of the vehicles could both smoothly pass through the narrowest place of the gas curtain and enter into the gas curtain jointed with air.Head type has little influence on the state and shape of the gas curtain and on the hydrodynamics.The drag coefficient is smallcst and changes stably in the process of exiting water.
