從伯努利原理得知，由於鳥類的翅膀具備了許多有助於產生巨大升力的條件，因此有助於在長距離飛行中節省能源損耗。為了提升小型橫軸式風機在低速風速下的捕風效率，故本計畫將對風機葉片進行仿生設計，並透過田口方法來使其達到最佳化。在本計畫的第一年，首先將利用葉片元素動量理論（BEMT）對標準型翼型（SD-8000）進行數學建模；再以三維設計軟體ANSYS來建立SHAWT的模擬平臺。接下來，將選取三種其條件合適於SD-8000翼型特徵的鳥類，如翅膀長度、羽毛數量和大小等特徵來作為田口最佳化設計的可控制因數。最後，通過變異分析（ANOVA）來得到可使SHAWT獲得最佳風能利用效率的設計參數。為了評估本計畫的可行性，將在第二年進行實機驗證實驗。首先，將利用3D列印機將SD-8000翼型以及仿生葉片塑出成型。接下來，將建構出以直流發電機、風扇、空氣流速計、轉速表和電子負載等組成的實驗平臺。最後，再將實驗結果與模擬結果進行對比分析以確認本計畫的可行性。

From the Bernoulli principle that, due to the birds' wings have a number of conditions help produce huge lift, thus helping to save energy loss in the long-distance flight. In order to enhance the small horizontal axis wind capture fan efficiency at low wind speed, so the program will biomimetic design of wind turbine blades, and through the Taguchi method to optimize it. In the first year of this project, the first use of blade element momentum theory (BEMT) for standard airfoil (SD-8000) mathematical modeling; and then to three-dimensional design software to create SHAWT ANSYS simulation platform. Next, select the appropriate features on the airfoil SD-8000 with the proviso that three kinds of birds, such as the length of the wings, feathers, number and size characteristics as to optimize the design of the control factor may be Taguchi. Finally, to get the best make SHAWT wind energy utilization efficiency of the design parameters by analysis of variance (ANOVA). In order to assess the feasibility of this project will be a real machine verification test in the second year. First, the use of 3D printing a plastic molding machine SD-8000 bionic airfoil blade. Next, the construction of an experimental platform to the dynamo, the fan, the air flow rate meter, tachometer and other components of the electronic load. Finally, then the results were compared with the simulation results to confirm the feasibility of this project.
