Wind turbine
The reason why the wind turbine of the wind turbine is thin and long is that the blade is the most fundamental and critical component of the wind turbine. wind turbine

, its good design, reliable quality and superior performance are the decisive factors to ensure the normal and stable operation of the unit. The harsh environment and long-term non-stop operation require that the blades be light in density, have the best fatigue resistance and mechanical properties, and can withstand extremely harsh conditions. challenges such as storms and random load tests. the inertia during rotation and its

are all normal and are transmitted to the entire production system of energy. Good load stability, good resistance; to corrosion, ultraviolet rays and impactslightning ; low power generation cost and lowest maintenance cost.
The other is to reduce weight. In order to meet the above requirements and improve the unit economics, increasing the blade size can improve the economics of wind power generation and reduce costs.
There should be a large relationship between the amount of wind energy received and the size of the wind receiving area of the blades of the device. This statement is not accurate. The reason wind energy is converted into kinetic energy is due to the interaction between the wind and the blades.
In order to expand the wind receiving range and reduce resistance.
1. The larger the area, the greater the resistance and it is easy to be destroyed in a hurricane. And the greater the resistance, the greater the energy loss.
2. The blade is one of the highest costs of the entire wind turbine, whichcan reduce costs.
3. Based on a blade length of 34 meters, when the wind is strong, the speed of the blade tip exceeds the speed of sound, causing special air waves. I'm not an expert, so I can't explain it. more clearly.
4. It seems that the 120 degree angle is also good for stress.
