我们使用多学科设计工具的功能来提供20 MW风力涡轮机的定义。从一个气动弹性模型，通过一个经典的缩放过程中，我们进行了气动结构优化的转子，通过一个分阶段的重新设计过程中，我们优化的主要特性的转子，包括叶片的形状，坚固性和一定量的本地结构剪裁。该过程基于一系列参数分析，以评估宏观设计参数变化对涡轮机基本性能的影响。重新设计活动在叶片质量减少和载荷缓解方面显示出显著的优势，突出了超大型转子的开发和优化方向。
We use the capabilities of a multi-disciplinary design tool to provide a definition of a 20 MW wind turbine. Starting from an aero-elastic model obtained through a classic scaling procedure, we conduct an aero-structural optimization of the rotor through a staged redesign process, in which we optimize primary characteristics of the rotor including the blade shape, the solidity and a certain amount of native structural tailoring. The process is based on a series of parametric analysis, in order to assess the impact of a variation of macro design parameters on the fundamental performance of the turbine. The redesign activity shows remarkable advantages in terms of blade mass reduction and load alleviation, highlighting directions for the development and optimization of very large rotors.
