This project focuses on the new ice-breaking method of wave induced by hovercraft, and considering the complex situation of the ice area environment. It focuses on the wave response of the hovercraft wave in the complex ice conditions such as the full ice surface and the ice-water mixed field. The characteristics of wave propagation in ice and ice-breaking mechanism will be investigated systematically, with the aid of numerical methods and model test. Revealing the coupling characteristics between fluid motion and ice-sheet. In addition, analyzing the internal response of ice sheet and carrying out related physical model tests. The numerical results and the experimental data are verified mutually, and the ice-breaking conditions of the wave induced by hovercraft are proposed. The research results have important theoretical and engineering significance for promoting the development of ice-water coupling dynamics and the research and development of polar and ice equipment in China.
