Experimental study wind turbine blades of locally wood based on local wind characteristics

Utilization of wind energy as renewable energy for areas not covered by the national grid. In previous study, from physical and mechanical analysis it was found that Jabon wood has better criterion as raw material of wind turbine manufacture compared to Balsa and Sengon wood with MOE value 4615,56 mPa and wood density value 0,34 g / cm3, while airfoil NACA 4415 has better stability coefficient of lift compared to SG 6042 on wind characteristics of Kampung Bungin. In this study manufacture of wind turbine blades using local wood in Indonesia, wind turbine sample testing performed in wind tunnel without using load and installing six point measurements in section test as a static pressure measurement to see the performance of wind turbine on a lab scale before installed in the field. Results obtained at a maximum speed of 680 rpm in maximum speed wind testing, on measurements static pressure at the point of the wind turbine and the area downstream of wind turbine being energized which is extracted by the wind turbine as the speed decreases at that point. The amount of energy used by the wind at a maximum wind speed is 18.74 watts. The wind speed profile is also used to rotate wind turbines at each wind speed.
