项目摘要
Rotors for wind turbines featuring flexible wings may optionally obtain a similar aerodynamic performance compared to conventional rotor blade concepts. In this context, the present research concentrates on the interaction between air flow and flexible structure of a membrane-type lifting surface, which has a significant influence on the aerodynamic performance on the one hand and on the structural loads on the other hand. The investigations are based on a wing configuration with load-bearing beam structure and flexible wing. The adaption characteristics of the flexible wing should on the one hand allow a desired target pressure distribution and aerodynamic performance, and on the other hand provide lower structural loads relative to conventional structural designs along with a reduction of peak loads in highly unsteady or gusty incoming flow. The focus of the work is on the methods for high-quality numerical simulations of the interaction between the flexible wing and the acting flow and the validation of the simulation results by performing wind tunnel experiments for a wing segment. A future aim is to show the possible potentials of “FlexWing” applications and to exploit the results of these investigations for feasibility and economic studies.
与传统的转子叶片概念相比,具有柔性翼的风力涡轮机的转子可以可选地获得类似的空气动力学性能。在这种背景下,本研究集中在空气流和柔性结构的薄膜型升力面之间的相互作用,它有显着的影响,一方面的气动性能,另一方面的结构载荷。研究是基于一个机翼布局与承载梁结构和柔性机翼。柔性机翼的适应特性一方面应允许期望的目标压力分布和空气动力学性能,另一方面相对于常规结构设计提供较低的结构载荷,沿着降低高度不稳定或阵风来流中的峰值载荷。工作的重点是高质量的数值模拟的方法之间的相互作用的柔性翼和作用流和验证的模拟结果进行风洞实验的翼段。未来的目标是展示“柔性翼”应用的可能潜力,并利用这些研究的结果进行可行性和经济性研究。
