Wind turbine
The reason why the wind impeller of the wind turbine is thin and long is that the blade is the most basic and critical component of
the wind turbine
, its good design, reliable quality and superior performance are the decisive factors to ensure the normal and stable operation of the unit. Harsh environment and long-term non-stop operation require the blades to be light in specific gravity and have the best fatigue strength and mechanical properties, and can withstand extremely harsh conditions such as storms. and random load tests; the elasticity of the blades, the inertia during rotation and its
vibration frequency
characteristic curve
are all normal and are transmitted to the entire power generation system. Good load stability; good resistance to corrosion, ultraviolet radiation and lightning strikes; low power generation cost and lowest maintenance cost.
The other is to reduce the weight. In order to meet the above requirements and improve the economy of the unit, increasing the size of the blades can improve the economy of wind power generation and reduce costs.
There should be a great 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 why wind energy is converted into kinetic energy is through the interaction between wind and blades.
In order to expand the wind receiving range and reduce resistance,.
