This Small Business Innovation Research (SBIR) Phase II project will develop an ultra-light, modular wind turbine for use in buoyant airborne wind energy systems. Reduced turbine weight has a cascading effect on total airborne system mass, allowing a significantly smaller, lower cost buoyant structure to be used to access high altitude winds. At heights up to 2,000 feet winds are strong and consistent, allowing for the production of low-cost, reliable power at a broad array of sites. High altitude winds have over five times the energy potential of ground winds accessed by tower-mounted turbines, opening the potential for a major new renewable energy resource to be harnessed. In addition, the containerized deployment of airborne wind turbines has the potential to expand wind development to sites that are not feasible today, including sites that are remote or have weak ground-level winds. Overall, the technology holds the potential to significantly lower energy costs and improve reliability for remote industrial, community, and military customers and represents a major step forward in unlocking the abundant high-altitude wind resource to help in the global pursuit of greater adoption of renewable energy sources.This SBIR Phase II project will focus on reducing the total weight of the wind turbine system. Turbine weight is one of the most critical cost drivers of buoyant airborne wind energy systems. For each kilogram removed from the turbine, an additional kilogram can be removed from the inflatable shell and tethers, resulting in a significantly smaller and lower cost system. The lightest commercially available small- to medium-sized wind turbine weighs 31.1 kilograms per kilowatt of capacity, which is too heavy for an economically-viable airborne turbine. By incorporating a compact, modular architecture, a lightweight permanent magnet direct-drive (PMDD) generator and high-strength composite materials, the proposed Phase II research effort aims to double the power density of traditional medium size turbines, making the proposed system suitable for use in an airborne application, while maintaining a high level of reliability and cost performance.

这项小型企业创新研究（SBIR）II期项目将开发超光模块化的风力涡轮机，用于浮动空气风能系统。减轻的涡轮机重对总空气寄生系统质量具有级联作用，从而可以使用明显较小的，较低的成本浮力结构来进入高海拔风。在高达2,000英尺的高度处，风是强大且一致的，可以在广泛的地点生产低成本，可靠的功率。高空风的五倍以上是塔式涡轮机进入的地面风能的五倍以上，这为要利用的主要新可再生能源提供了潜力。此外，机载风力涡轮机的集装箱部署有可能将风开发扩大到当今不可行的地点，包括偏远或较弱的地面风。总体而言，该技术具有显着降低能源成本并提高对远程工业，社区和军事客户的可靠性的潜力，并代表着释放丰富的高空风资源迈出的主要一步，以帮助全球追求更大的可再生能源采用。这一SBIR II期项目将集中于减少风力涡轮机的总重量。 涡轮的重量是浮力机载风能系统最关键的成本驱动因素之一。对于从涡轮机中取出的每公斤，可以从充气壳和tether中取出额外的千克，从而产生明显较小和较低的成本系统。最轻的市售中小型风力涡轮机的容量为每千瓦时31.1千克，对于经济上可行的机载涡轮机来说太重了。通过合并紧凑的模块化架构，轻巧的永久磁铁直接驱动器（PMDD）发电机和高强度的复合材料，拟议的II期研究工作旨在使传统中型涡轮机的功率密度增加一倍，从而使所建议的系统适合在空中应用中使用，同时保持高度的可靠性和成本性能。
