Abstract

Lack of fossil fuel as energy resource of the world triggers a rapid development in renewable energy. Wind energy as one of renewable energy resource has a great potential to solve world’s energy needs especially in Indonesia. Nevertheless, the application of wind energy technology is remain undone due to inappropriate design. One way to solve this problem is by creating a wind turbine blade design which suits wind characteristics in Indonesia. The blade which is designed by 50% and 75% linearization optimization can capture 53% of wind energy at Tip Speed Ratio (TSR) of 5. By using Russian pine wood as material, the design is being simulated under critical wind speed condition and proved to be feasible in this relating condition with Factor of Safety of 5.43. The research method uses various theoretical calculation and software simulation; QBlade and SolidWorks. The purpose of this scientific article is a NACA 4415 Taperless Twsitless Pitch +7 wind turbine blade is applicable in wind turbine system in order to produce an affordable, compact, and efficient wind turbine blades appropriate for wind characteristic in Indonesia.
