Each grassland herdsman family in Inner Mongolia uses wind energy to generate electricity. A large-scale wind power plant is currently under construction in the northwest region of Baotou City, Inner Mongolia. The tower shaft is more than 50 meters high and each fan blade is more than 10 meters long. Hundreds of them scattered across the meadows are very spectacular. If you have the chance, you can come and take a look.
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, which can 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 specific air waves.ials. 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.
