Wind power vertical axis red lantern wind turbine

Vertical axis wind turbines do not need to oppose the wind when the wind direction changes, which is a major advantage compared to horizontal axis wind turbines.Although there are various types of wind turbines, they can be summarized into two categories: (i) horizontal axis wind turbines, where the rotation axis of the wind wheel is parallel to the direction of the wind; and (ii) vertical axis wind turbines, where the rotation axis of the wind wheel is perpendicular to the ground or the direction of the airflow. There are several types of vertical axis wind turbines that use resistance to rotate, including wind wheels made from flat plates and cups, which are a pure resistance device; and S-shaped windmills, which have partial lift but are mainly resistance devices. These devices have a large starting torque, but a low tip speed ratio and provide a low power output for a given wind turbine size, weight and cost.vespel SP-1 machined parts Pc Cnc Machined Part

Vertical axis wind turbine (VAWT) is classified into resistance type and lift type. The drag type vertical axis wind turbine mainly uses the drag force generated by the air flowing through the blades as the driving force, while the lift type uses the lift force generated by the air flowing through the blades as the driving force. Because the blade in the process of rotation, with the increase of speed resistance sharply decreases, while the lift force will increase, so the efficiency of the lift type vertical axis wind turbine is much higher than the resistance type.
