Abstract
Wind energy is used for eco-friendly electrical power generation with high moment forces through turbine rotation with the help of wind. Although it has good electrical power generation, the noise produced by a wind turbine impacts the environment by creating different sound pressure levels. In this paper, the design of horizontal-axis wind turbine blades (NACA 63-215), which have a rotor diameter of 80 m, will be done by using computer-aided modelling and computer flow analysis software, in which the blades are designed using the theory of aerodynamics by taking appropriate twist angles and chord lengths. At the end of design, it is scaled to 1:200 ratio for 3D printing of blades and also finding and studying the sound power levels through the sound level meter, which is electro acoustic integrated system, which gives different frequencies based on sound pressure levels for the 3D-printed blade.
