Abstract: It is an important problem for improving the vane’s performance, rigidity and the stability of the wind turbine. There are many factors offering the inspiration for bionic design of the wind turbine. These factors include integrate of the organism’s form, function, structure and material, and the ability to adapt to the environment. The bionic process is an innovative and comprehensive analysis process. The TRIZ theory is applied to the wind turbine’s research process. The TRIZ theory can let people realize the necessity of the innovating and the development tendency of the wind turbine. It makes the research process more systematic and more regularity. This paper applies the TRIZ theory to count the wind turbine’s related data and to make a chart. Through contrasting the chart to the standard chart, the development stage and the development tendency of the wind turbine are found. Finally, through modeling and analyzing the fins, the mechanical data of the fins module can be got.
