Design of Tapperless Type Horizontal Axis Wind Turbine (Hawt) Blades using Mahogany Wood Material

Abstract

Indonesia has quite large wind energy resources spread across various regions, so it has the potential to be developed into PLTB. Energy needs in Indonesia continue to increase and the government is committed to utilizing new, renewable energy to achieve emission reduction targets. However, efforts to utilize wind energy are still not optimal due to several reasons, especially research and research capabilities related to PLTB. The blade is the main component in the wind turbine system and is the system that first receives the wind and then converts it into mechanical energy. This research aims to determine the performance and manufacture tapperless type wind turbine blades with NREL's S822 airfoil using Qblade and Solidworks software. The design and simulation results show that the resulting blade has a blade radius of 1 meter, a blade or chord width of 0.12 m. The twist angle from the base to the tip of the blade ranges from 11.69º to 5.05º and a power of 500 W is obtained at a rotational speed of 262 rpm.
