Tethered airfoil HAWP devices have 3 main components: 1.) the airfoil or lifting surface, 2.) the tether, and 3.) the anchor point or base station [1]. One of the benefits of these devices over conventional ground based wind turbines is that the material footprint of each device is significantly less than their ground based counterparts for the same amount of power generated [6]. These devices do require slightly different materials than HAWTs for example, however they are not significantly more complex, which should allow them to penetrate the market in a similar fashion to how ground based turbines did and became widespread. The first main component of these HAWP devices, the airfoil or lifting surface, could be made of a variety of materials. If the device uses a parasail as in [1] [4] [6] [7], then it is likely to be made of conventional parasail materials, namely nylon. If instead of a parasail, an airfoil is used, then such an airfoil will likely be made out of similar materials to airplane wings. Airplane wings and thus airfoils, can be made out of a variety of different materials, ranging from wood and cloth used on old WWI planes, to aircraft grade aluminum used in modern airliners, to composite materials found in today’s gliders. Any of these materials could be potentially viable for the airfoil, as different materials are suited to different properties of the airfoil [1]. If the airfoil also has onboard power generation in the form of propellers that spin motors,…
