Numerical Analysis About High-speed Entry Water Of Wing-In-Ground-Effect-Plane

In this paper, the numerical analysis of the high-speed water entering of the Wing-In-Grade-Effect-Plane is carried by the Fluid-structure Interaction way of the ANSYS/LS-DYNA. Some significant conclusions are given through the analysis the simulating results.At the beginning of this paper, the research history development of the water-entry structure is reviewed. Secondly, the basic principle and solving steps of the FEM methods, as well as the calculating method are introduced. Through the Numerical Simulation of the high-speed water entering of the Wing-In-Ground-Effect-Plane, we get the 3D images of Entering the water, the water upheaval, splashing water, pressure-wave and the speed-acceleration curve.In one word, the results of this research and calculation may provide a technical support for the design of Wing-In- Ground-Effect-Plane in some degree, and also are useful for the dynamics analysis of other high-speed water entering structures.
