摘要
Abstract
The underwater supercavitating vehicle utilizes the supercavity generated during high-speed navigation to enclose most of the missile body,preventing the surface of the missile body from contacting water fluid.Thus,it can significantly reduce frictional resistance and is one of the important drag reduction technologies for underwater super-high-speed navigation at present.Inside the supercavity,a part of the vehicle tail will collide with the supercavity wall or slide on it.The resulting hydrodynamic force is called the supercavitation sliding force,which is a key hydrodynamic force affecting the motion performance of underwater vehicle bodies and is also an important topic and difficulty in the field of supercavitating vehicle body research.In this paper,the development history of the theoretical research on supercavitation sliding force is reviewed.The intrinsic connection between the supercavitation sliding force and the theory of planar entry into water is analyzed comparatively.It is revealed that the modeling method of supercavitation sliding force is the extension and application of WAGNER's theory of planar entry into water on curved water surfaces.It points out that the key breakthrough among them is to solve the problem of objects entering water on curved water surfaces,providing ideas for accurately understanding and further developing the supercavitation sliding force model.关键词
