摘要

基于叶片单元动量理论的叶片初步设计优化弦角和扭角均为非线性分布，增加了叶片制造的复杂性，并不能保证叶片的最佳气动性能。本文采用Prandtl-Glauert校正模型，通过将弦与扭角线性化的情况1、情况2、情况3和鞋底弦线性化的情况4，研究了线性化对气动性能的影响。研究了Shen校正模型的线性化效果，并与Prandtl-Glauert校正模型的线性化效果进行了比较。对S809型风力机叶片型线进行了仿真。结果表明，采用沈校正模型的案例4具有较高的气动性能和易于制造的优点，是最佳的线性化技术。

Effects of blade design linearization on aerodynamic performance of horizontal axis wind turbine

The optimized chord and twist angle of the preliminary blade design through Blade Element Momentum theory are non-linear distributions, which adds to the complexity of blade manufacture and does not always guarantee the best aerodynamic performance. In this paper, the effect of the linearization on aerodynamic performance using Prandtl-Glauert correction model was investigated through four cases: case 1 and case 2 and case 3, where the chord and the twist angle are linearized and case 4, where sole chord is linearized. The effect of the linearization using Shen correction model while making a comparison to the linearization using Prandtl-Glauert correction model was also studied. The simulation is conducted for S809 wind turbine blade profile. The results show that case 4 using Shen correction model represents the best technique of linearization in terms of higher aerodynamic performance and easy manufacturing process.
