ABSTRACT The global wind power systems at present include two main types: (1) horizontal axis wind turbine (HAWT) system, and (2) vertical axis wind turbine (VAWT) system. This paper studied on wind blade models development and reality manufacture. First, the researcher collected and read related literature of wind power systems. Second, the researcher studied on HAWT blade (including one traditional model and eight innovative models) and VAWT blade (including one traditional model and eight innovative models), and adopted the methodologies of Bionics and TRIZ to innovate. There are three VAWT blades used TRIZ theory, eight HAWT blades and five VAWT blades used Bionics. Third, the researcher used 3D direct modeling software (e.g. SpaceClaim, SolidWorks and AutoCAD) to draw the figures, and used RP 3D printer (FORTUS 360mc) to manufacture the wind blade models. Fourth, the researcher also used an experiment device (WINDTRAINER) to propel and measure the voltages, currents of the wind blade models, adjusted the wind speed (4 m/s~12 m/s), compared their watts (Pa) and rotor power coefficient (Cp). Thus, the researcher can find the higher efficient wind blades of HAWT and VAWT types. The researcher found the best Cp value of HAWT blade is Bentley type, the better Cp value is four-leaved clover type; and the best Cp value of VAWT blade is Tai-Chi spiral type, the better CP value is Taiwan shape type. The other, the better Cp value of commercial advertisement for attracting the customers are Bentley type and Taiwan shape type. The baseball set shape wind blade is quite attractive, but its Cp value needs to be improved. These customer oriented innovative wind blades are designed to go beyond the thinking of the traditional wind blade models. The next, in the area of reality manufacture, we purchased and installed one 300W type VAWT power system (including an arc type blade, a Spiral type blade, a generator, a cylinder about 3 meters in height, a controller, two batteries, and a load of LED streetlamp). We used one PC and its monitor package to test and analyze this system functions. The wind power system got more watts (Pa) during the winter in 2014 typhoon Soudelor and typhoon Dujuan and the winter in 2015,and typhoon Nepartak and the winter in 2016. Finally, this research result is valuable in teaching and R&D of wind power generation. Furthermore, we use these innovative wind blades to take part in some international invention exhibitions and won some prize that can win the honor for CTU.
