Abstract
The numerical method is used to simulate the whole process of seaplane landing movement attitude and force, which is a complex problem combining water vapor two-phase flow, kinematics and dynamics. In this paper, the global motion grid method based on Fluent commercial software is combined with VOF method for free surface capture and six-degree-of-freedom model for motion state simulation. The numerical simulation of the water surface landing of a certain type of seaplane is carried out. The simulation results verify that the overall motion grid method has good adaptability when dealing with the surface landing problem of seaplanes. Through the simulated overload curve, motion state parameters and water surface condition, the landing process is divided into three stages: impact, water skiing and floating. Through the analysis of each stage, the general understanding of the water surface landing process is summarized. Methods and references are provided for the design and development of seaplanes.
