The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project aims to address the declining U.S. distributed wind turbine (DWT) market and support the transition to renewable energy sources. The DWT market has experienced a decline since 2012, mostly due to low reliability and high levelized cost of energy. However, the deployment of DWTs is crucial to meet ambitious green energy goals set by utilities and governmental agencies. This project addresses these challenges by increasing the ease of manufacturing and using readily available materials. The project will also improve an ultra-efficient load path that yields a uniquely low-cost and low-mass structure. Additionally, the proposed design achieves a larger rotor-swept-area and increases overall power extraction efficiency, making the wind turbine more efficient, lighter, and inexpensive compared to typical horizontal-axis and vertical-axis wind turbines. The value proposition for consumers is a cost savings of approximately 40% or more with respect to DWT competitors. This SBIR Phase I project proposes to develop a new wind power technology and provide a proof-of-concept for its viability. The project team includes experts in structural dynamics, control system design, turbine design, computer-aided engineering, power electronics and power transfer, and prototype and certification testing. In Phase I, a complete full-scale design of the DWT will be created, including detailed aeroelastic modeling, control development, and structural evaluation of the components. The research pillar of Phase I involves the creation of a rigorous aero-servo-elastic model, a detailed 3D solid model, and finite element analyses of the key components. The control system will be developed based on analytical analyses, and the team will work toward proper control specifications and constraints to be met by the dynamic system. The anticipated technical results include a refined estimate of the power coefficient, an optimized strategy for independent blade control and load reduction, improved design driving load values for the key components, decreased potential for aero-elastic instabilities and resonances, and the improved refined levelized costs of energy estimates.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该小企业创新研究 (SBIR) 第一阶段项目的更广泛影响/商业潜力旨在解决美国分布式风力涡轮机 (DWT) 市场不断下滑的问题，并支持向可再生能源的过渡。自 2012 年以来，DWT 市场经历了下滑，主要是由于可靠性低和能源平准化成本高。然而，DWT 的部署对于实现公用事业和政府机构制定的雄心勃勃的绿色能源目标至关重要。该项目通过提高制造的便利性和使用现成的材料来解决这些挑战。 该项目还将改进超高效的负载路径，从而产生独特的低成本和低质量结构。此外，所提出的设计实现了更大的转子扫掠面积并提高了整体功率提取效率，使风力涡轮机比典型的水平轴和垂直轴风力涡轮机更高效、更轻且更便宜。与 DWT 竞争对手相比，消费者的价值主张是节省约 40% 或更多的成本。 SBIR 第一阶段项目提议开发一种新的风力发电技术，并为其可行性提供概念验证。项目团队包括结构动力学、控制系统设计、涡轮机设计、计算机辅助工程、电力电子和电力传输以及原型和认证测试方面的专家。在第一阶段，将创建 DWT 的完整全尺寸设计，包括详细的气动弹性建模、控制开发和部件的结构评估。第一阶段的研究支柱包括创建严格的航空伺服弹性模型、详细的 3D 实体模型以及关键部件的有限元分析。控制系统将根据分析进行开发，团队将致力于制定动态系统要满足的适当控制规范和约束。预期的技术成果包括功率系数的精确估计、独立叶片控制和减载的优化策略、改进关键部件的设计驱动载荷值、降低气动弹性不稳定性和共振的可能性以及改进的精细平准化成本该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
