Wind velocity increases exponentially with altitude from the ground. Hence, higher altitude is much better location to extract wind energy since it is proportional to the cube of the velocity. This study aims research and development for harvesting wind energy at high altitude using two types of airbone wind rotors and the energy transfer method using the torsional elastic deformation of polymeric fiber tether ropes. In this study, we constructed two types of airbone wind rotors and measured torque and tension of the tether ropes induced by the wind rotor, and also made a comparison with a model analysis to examine the performance of the wind rotor. The results suggested that the constructed wind rotor has a promising structure for harvesting wind energy at high altitude. We also studied the material properties of carbon fiber reinforced plastic (CFRP) manufactured with a vacuum assisted resin transfer molding (VaRTM) to construct the airbone wind rotors.

风速随着距地面的高度呈指数增加。因此，较高的海拔是提取风能的更好位置，因为它与速度的立方成正比。本研究旨在研究和开发使用两种类型的气骨风力转子在高空采集风能以及利用聚合纤维系绳扭转弹性变形的能量传输方法。在本研究中，我们构建了两种类型的气骨风力转子，并测量了风力转子引起的系绳扭矩和张力，并与模型分析进行了比较，以检验风力转子的性能。结果表明，所构建的风力转子具有在高空收集风能的良好结构。我们还研究了采用真空辅助树脂传递模塑 (VaRTM) 制造的碳纤维增强塑料 (CFRP) 的材料特性，用于构造气骨风力转子。
