In the design process of wind turbine blades, NcR value is a parameter that needs to be strictly controlled. Because once the blade flutter occurs, it will not only affect the performance of the wind turbine, but also cause damage to the blade itself and even cause safety accidents. Therefore, designers need to optimize the blade material and structure to improve the NcR value and ensure the long-term stable operation of the fan.
In addition to controlling the NcR value in the design stage, fans need to constantly monitor and adjust the NcR value during operation to ensure the health and stability of fan components. At the same time, with the continuous emergence of new materials and new processes, the NcR value of wind turbine blades is also constantly improving, which has injected new impetus into the development of wind power generation industry.
