这项工作提出了一个综合的多学科风力涡轮机优化框架，利用国家的最先进的气动弹性和结构工具，能够同时设计的外部几何形状和内部结构的叶片。该框架被用来设计一个10兆瓦的转子约束不超过现有的参考风力涡轮机的设计负载。结果表明，通过对叶片的内部结构和空气动力学形状进行组合几何剪裁，可以实现显著的被动载荷减缓，从而允许叶片延长9%，AEP增加8.7%，而不会增加叶片质量，也不会显著增加轮毂和塔架上的极限载荷和疲劳载荷。
This work presents an integrated multidisciplinary wind turbine optimization framework utilizing state-of-the-art aeroelastic and strutural tools, capable of simultaneous design of the outer geometry and internal structure of the blade. The framework is utilized to design a 10 MW rotor constrained not to exceed the design loads of an existing reference wind turbine. The results show that through combined geometric tailoring of the internal structure and aerodynamic shape of the blade it is possible to achieve significant passive load alleviation that allows for a 9% longer blade with an increase in AEP of 8.7%, without increasing blade mass and without significant increases in ultimate and fatigue loads on the hub and tower.
