PERANCANGAN TURBIN ANGIN SUMBU HORIZONTAL (TASH) SKALA MIKRO MENGGUNAKAN AIRFOIL NACA 4412 DENGAN VARIABEL KECEPATAN ANGIN 4 M/S

Horizontal axis wind turbines are wind turbines with a horizontal axis like the propeller of an airplane in general. The purpose of this design is to design an appropriate horizontal axis wind turbine with the existing potential data in the Batu area, to design and perform calculations for wind turbine components such as hubs (connecting shafts to blades), airfoil blades, guide tails, tower poles. The NACA airfoil is a form of airfoil for aircraft wings developed by The National Advisory Committee for Aeronautics (NACA) (Fouatih et al., 2016). The shape of the NACA airfoil is described using a series of numbers that follow the word “NACA” Wind speed is the average speed of the wind flowing over the earth's surface. Many factors influence it (Jung & Schindler, 2019). The total power of the wind current is the power that is proportional to the rate of kinetic energy of the incoming wind curren
