近年来，风能作为可能的替代可再生能源之一在约旦引起了极大的关注。在这一领域，几乎所有的地方研究和开发活动都是针对能源系统的探索、开发和最佳利用。现在是在当地科学（学术）工作和当地工业之间建立联系的时候了，以便产生一种可用的技术，增加当地在约旦不可避免地新兴的风能工业中的份额。为了实现这一目标，需要一个基础良好的制造基地。风能转换器最重要的部件是转子。转子的效率由其轮廓（翼型截面）和相应的空气动力学设计来表征。本文讨论并实施了小型涡轮机翼型的选择方法和叶片的气动设计。结果发现，对于5米长的小叶片，两种不同的翼型在翼展的外三分之一处混合就足够了，并表现出良好的强度和空气动力学特性。玻璃纤维增强塑料作为一种复合材料，被用于设计转子叶片。然后将该转子安装在15 kW并网变桨距控制电机上。静态验证载荷试验表明，该叶片可以承受10倍于正常工作推力的载荷，现场性能试验表明，转子叶片的实测平均功率系数为41.2%。(C)1999爱思唯尔科技有限公司。保留所有权利。
Wind energy has attracted a great deal of attention in recent years in Jordan as one of the possible alternative renewable energy resources. Almost of the local research and development activities in this field were directed to explore, develop, and optimal utilization of energy systems. The time has come to establish a link between local scientific (academic) work and local industries to produce a usable technology which will increase the local share in an inevitably emerging wind energy industry in Jordan. To achieve this goal, a well founded manufacturing base is required. The most important component of a Wind Energy Converter is the rotor. The efficiency of a rotor is characterized by its profile (airfoil section) and the corresponding aerodynamic design. A selection procedure of airfoil section and the aerodynamic design of the blade for a small wind turbine are discussed and implemented in this paper (Part I). It is found that for small blades up to 5 m long, two different air foils mixed at the outer third of the span will be sufficient and demonstrated good strength and aerodynamic characteristics. As a composite material, the Glass Fiber Reinforced Plastic was used in designing the rotor blade. This rotor was then installed on 15 kW grid-connected-pitch-controlled machine. A static proof load test indicated that this blade could withstand loads ten times the normal working thrust, and a field performance test showed that the rotor blade has a 41.2% measured average power coefficient.
