Wind turbine blades must undergo tests such as fatigue and static load testing. Fatigue testing simulates an operational lifespan of 20 to 30 years, verifying long-term durability within a period of six to eight months.
Static load testing simulates extreme conditions-surpassing even the most powerful typhoons-by applying ultimate static loads to the blades to assess their maximum load-bearing capacity and structural integrity.
These tests are conducted on specialized test stands featuring high-strength concrete foundations extending 40 meters deep (12 meters above ground and 28 meters below) to withstand the immense loads generated during testing.
The CQC New Energy Innovation Base, located in the Sheyang Port Economic Development Zone in Yancheng, Jiangsu Province, is dedicated to wind turbine blade testing.
As of 2023, the facility has the capacity to test four blades simultaneously, with plans to expand this to six blades in the 200-meter class by 2026. With an annual testing capacity of 20 blade sets and 50 wind turbines, the base provides services to numerous enterprises, covering onshore, nearshore, and deep-sea turbine models.
