Historical Perspective on Blade Design
Historically, wind mills typically featured four blades for best efficiency and functionality. The design of four-blade wind mills wasn't merely arbitrary; it was chosen based on practical reasons. These four-blade wind mills were commonly utilized for grinding grain and other essential purposes.
In 1919, the Betz Law was formulated, which states that an ideal rotor can extract up to 59% of wind energy. This law laid the foundation for understanding the limits of wind turbine efficiency. Despite this theoretical limit, modern wind turbines have evolved to feature three blades, surpassing the Betz Law's expectations by achieving up to 80% efficiency.

When comparing the efficiency of two-bladed and three-bladed wind turbines, it is essential to take into account factors such as drag, weight, stability, and energy extraction capabilities. Two-bladed turbines are known for their higher efficiency due to reduced drag and weight, allowing them to operate at higher rotational speeds and optimize energy extraction while reducing torque. On the other hand, three-bladed turbines offer improved stability and performance across a wider range of wind speeds. The Betz law suggests that an ideal rotor can extract up to 59% of wind energy, although modern turbines have achieved efficiencies of up to 80%. To provide a clearer comparison between the two types of turbines, let's take a look at the table below:
