The strength of a wind rotor refers to the ratio between the sum of the areas of the wind rotor blades and the swept area of the wind rotor.
Wind wheel strength is a mechanical engineering term announced in 2013. The ratio of the total projected area of the rotor blades to the swept area of the rotor. Blade area is one of the important parameters of wind turbines, which affects the performance and efficiency of wind turbines. Generally speaking, the larger the surface area of the blades, the more wind energy is captured and the higher the efficiency of electricity production. But at the same time, excessive blade surface area will also have a negative impact on the operational stability of the wind turbine.
In addition to blade area, the power generation efficiency of wind turbines will also be affected by other factors, such as wind energy resources, wind speed, densityair pressure, unit speed, weather conditions, etc. Therefore, these factors must also be considered when designing and installing wind turbines to ensure efficiency and stability of electricity generation.
Wind rotor sweep area, also called wind rotor sweep area, refers to the area occupied by the wind turbine rotor on a plane perpendicular to the wind direction at a certain time during wind rotation. turbine rotor. The wind sweeping area of the wind turbine is an important parameter to measure the wind capturing capacity of the wind turbine, which directly affects the power generation efficiency of the wind turbine.
The concepts and types of wind turbines are as follows:
In electrical and energy science, wind turbines refer to wind turbine components that convert wind energy into mechanical energythat. . Composed of blades and hub. In traditional Chinese medicine, the wind chakra refers to the cornea. There are many types of wind turbines, but they can be summarized into two categories: horizontal axis wind turbines, the axis of rotation of the wind turbine is parallel to the wind direction, vertical axis wind turbines, the axis rotation of the wind turbine; is perpendicular to the ground or to the direction of airflow.
There are several types of vertical axis wind turbines that use resistance to rotate. Among them are wind turbines made of flat plates and quilts, which are a pure resistance device; S-type wind turbines have partial lift, but it is mainly a resistance device and is the main competitor to the horizontal axis wind wheel. Other forms of vertical axis rotors include Magnus effect rotors.
