The thinness is to comply with the principle of aerodynamics. But it is really not small. Some blades are fifty or sixty meters long. Wide blades and multiple blades are suitable for wind turbines with low wind speed and low rotation speed, and their efficiency is low. Wind power Generators mostly use low solidity ratio wind turbines with few blades and narrow blades, which can operate with higher efficiency and high speed. Generally, domestic...

Introduction Why are the blades of wind energy generators so small? The purpose is to comply with aerodynamic principles. But they are really not small. Some blades are fifty or sixty meters long. Wide blades and multiple blades are suitable for low wind speeds.
