Taperless blade manufacturing using NREL’S 833 air foil on horizontal axis wind turbine

Wind is an energy source that is abundantly available in nature and is a renewable energy that is environmentally friendly and has good work efficiency. Indonesia has a wind potential of 978 MW with wind speeds generally 6-8 m/s in onshore areas and above 8 m/s in offshore areas. Therefore, with abundant wind potential, we should be able to take advantage of this energy. This paper will analyze the performance of NREL's 822 Taperless type using the QBlade application. The research method used begins with a literature study to find natural parameters which will later be calculated with the help of excel in order to get the geometry parameters of the blades, then enter the data into the QBlade software by dividing the blades by 10 elements on the blades and optimizing the blades in the Qblade software. Manufacture of blah with mahogany jens wood material. This paper will discuss the manufacture of taperless blades with NREL's 822 airfoil which was previously designed using the MS Excel and Q-Blade applications and then designed using the Solid Work application.
