1. The length of the blade affects the swept area and determines the wind catching ability. According to Betz's rule, only about half of the wind is actually captured by wind turbines.
2. The aerodynamic shape of the blade can be clearly seen from the cross-section of the blade. It is important to ensure that the airflow does not move too slowly through the blade, causing turbulence, and does not pass too fast, causing energy waste.
3. Section thickness increases gradually from the tip to the root of the blade thickness to bear greater load and bending moment. If the load is not very important, in general the ratio of thickness to length is 10-15%. The flat part near the root of the blade helps to improve the efficiency of wind capture.
4. The torsional design of the blade allows for an increase in rotation speed with an increase in blade length. This, in turn, allows for a continuous change in windward angle as the blade extends. To maintain an optimal angle of attack in the windward area of the blade, it is necessary to design the blade in a torsional form.
5. The number and speed of blades are typically set at a ratio of 7 to 10 times the wind speed. As the rotation speed increases, the number of blades also rises. This necessitates a reduction in blade size, which presents challenges in ensuring sufficient strength. However, at high speeds, the air catching efficiency of the blade also declines, increasing its vulnerability to environmental erosion and bird impact.
