Abstract
Underwater vehicles will be subjected to a great impact load at the moment of water entry,which may cause damage to the structure of the projectile and even affect the stability of the water entry trajectory.In this paper,the designed head-shaped and classical head-shaped test projectiles are taken as the research objects,and the trans-media high-speed water entry impact load experiment is carried out.The variation law of axial overload and impact loads of the streamlined test projectile during the trans-media high-speed water entry process is obtained.The motion law and cavitation development law during the trans-media high-speed water entry process are verified,and the flow field characteristic and evolution process are analyzed.The experimental results show that with the increase of velocity,there are cavitation closure stage and axial overload stability stage in the flow formation and development stage.The variation law of axial overload and water entry impact loads of different head types in the process of high-speed water entry across the media is compared and analyzed,and compared with the water entry loads of MK46 projectile and supercavitating head type test projectile.The results show that the resistance coefficients for projectiles of streamlined shape,MK46 shape and supercavitation shape are 0.023,0.265 and 0.1,respectively.The streamlined head used in this paper has a significant effect on water entry and load reduction.关键词
