From the Bernoulli's principle knows that the wing feature of birds is well-facilitated to generate great lift force for saving energy in the long-distance flight. In order to improve the wind-harvesting efficiency for the small horizontal axis wind turbines (SHAWTs) under the condition of low-speed wind (less than 5 m/s), a bionic design for the wind blades by using Taguchi's method is developed. In the 1st year of this project, first, the blade element momentum theory (BEMT) is used to drive the mathematical model of the standard-pattern airfoil (SD-8000), and then the simulation platform of SHAWT based on the 3D design software ANSYS is built. Next, the wing features such as the length, feather number and size e.g. of three kinds of birds that can fit to the SD-8000 airfoil are selected and determined as the controllable factors in the Taguchi's optimization. Finally, through the analysis of variance (ANOVA) the design parameters which can result in the optimal efficiency of harvesting wind energy for SHAWT can be obtained. In order to assess the feasibility of this project, the physical experiments will be carried out in the 2nd year. First, the SD-8000 airfoils and bionic blades designed in the 1st year will be molded by using a 3D printer. Next, the experimental platform composed with a DC generator, fan, aerodromometer, tachometer, and electronic loads e.g. will be built. Finally, the experimented results and the simulation ones will be compared and analyzed.
