文档介绍：摘要
当今世界,风力发电已成为新能源主题之一。与此同时,风力发电机叶片的发展也十分迅速。其良好的设计、可靠的质量和优越的性能是保证风力发电机组正常稳定运行的决定因素。叶片的翼型设计、结构形式直接影响风力发电装置的性能和功率。叶片是风力发电机中最核心的部分,是风力发电机中叶轮的最基础和最关键的部件,所以叶片设计的好坏,决定了风力发电机的优劣。叶片也是受力最为复杂的部件。设计良好的叶片是风力机获得较高风能利用系数和较大经济效益的基础。叶片作为接收风能的主要部件,在整个风电设备系统中的地位尤显重要,要求其具有合理的翼型设计。优质的材料和先进的工艺,其设计!制造和性能成为了重点研究和大力发展的目标"目前对于叶片的研究集中在翼型、结构、材料和工艺制造方面。

Abstract
In today's world,wind power has e one of energy。 theme. At the same time, the development of wind turbine blade is also very quickly. The good design, reliable quality and superior performance is to ensure that the determinants of the normal and stable operation of wind turbines. Airfoil design, blade structure directly affect the performance and power of wind power generation device. The blade is the core part of the wind generator, is the most basic impeller in wind power generator and the most ponents, so the blade design is good or bad, the wind turbine performance. The leaf is the plex part. Blade design is a good wind turbine foundation for high wind energy utilization coefficient and greater economic benefits. Leaves as receiving the ponents of the wind energy in the entire wind power equipment system is particularly important, a reasonable airfoil design! Quality materials and advanced technology, designed manufacturing and performance e the focus of research and vigorously development for blade research focused on the airfoil! structure! materials and manufacturing process.
Key words:Blade;blade design
