Tips: Why do wind turbines use three blades?

Three leaves are easy to balance, and too many leaves are difficult and expensive to balance. So, the smaller the number of blades, the better?

First of all, the advantage of multiple blades lies in the larger torque conversion rate, but in terms of energy conversion rate, the efficiency of 4-blade and 5-blade wind machine is lower than that of 3-blade wind machine. The main reason is that the multi-blade wind machine, due to the large resistance, caused a considerable part of the disturbance to the rotation of the blade turbulence, thus reducing the conversion of energy.

So 3 leaves is better than 4 or 5 leaves. Second, too few blades affect the efficiency of power generation.

The smaller the blade is, the higher the rated speed is, and the higher the speed is to a certain degree. The circumferential linear speed of the blade tip is very large, which causes large wind resistance. The resistance moment limits the further improvement of power generation and speed. Therefore, too little blade is not good, three blade is mainly good balance, and low cost, after a long time to verify, has become today's common fan form.
