In terms of efficiency, the efficiency of two-blade wind turbines is slightly higher than that of three-blade wind turbines, around 0.05%;
In terms of dynamics, the inertial force and the aerodynamic force Wind turbines with three blades are relatively uniform, while those of wind turbines with two blades are. The forces exerted on the blades are different when they are in the vertical and horizontal directions, that is, the dynamic characteristics are unequal;
< p>In terms of noise, noise is generally related to the speed at which the blades cut the air, so the noise of the two-blade wind turbine It is more important than the three-blade wind turbine because it rotates at high speed;Visually you can feel that the The three-blade wind turbine seems much more comfortable when rotating.
