The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is in enabling more efficient Annual Wind Energy Production (AEP) while reducing the cost of energy (COE). This will make wind energy more attractive economically, improve the energy security of the U.S, create jobs, and indirectly help reduce greenhouse gas emissions. A 2% AEP increase is generally considered attractive. Two turbines (5kW and 50kW) tested during Phase I have shown an increase in AEP between 2% to 8% while reducing the COE by 1% to 6%. About 150,000 turbines worldwide can be potentially be retrofitted with this technology.This project will address challenges related to aerodynamic efficiency of wind turbines and the cost of wind energy. It is based on a deeper understanding of wind turbine aerodynamics from a more 3-dimensional point of view; most wind turbine designs are based on 2- dimensional theories. The key technical challenge in bringing this technology to market is to demonstrate the increase in AEP of utility scale turbines retrofitted with our deflector technology in realistic field conditions while reducing the COE. This will be addressed by performing testing at a few customer wind farms and NREL testing centers. The R&D plan consists of designing, manufacturing, and installing deflectors on a few utility size turbines (30-100 meters diameter rotors). The tests will include power performance comparison between baseline and retrofitted turbines according to international standards.

这个小型企业创新研究（SBIR）第二阶段项目的更广泛的影响/商业潜力是实现更有效的年度风能生产（AEP），同时降低能源成本（COE）。这将使风能在经济上更具吸引力，提高美国的能源安全，创造就业机会，并间接帮助减少温室气体排放。2%的AEP增长通常被认为具有吸引力。在第一阶段测试的两台涡轮机（5 kW和50 kW）显示出AEP增加2%至8%，而COE减少1%至6%。全世界大约有15万台涡轮机可以利用这项技术进行改造。该项目将解决与风力涡轮机的空气动力学效率和风能成本有关的挑战。它基于从更三维的角度对风力涡轮机空气动力学的更深入理解;大多数风力涡轮机设计都基于二维理论。将该技术推向市场的关键技术挑战是在实际现场条件下证明采用我们的导流板技术改造的公用事业规模涡轮机的AEP增加，同时降低COE。这将通过在一些客户风电场和NREL测试中心进行测试来解决。研发计划包括设计，制造和安装偏转器在一些实用尺寸的涡轮机（30-100米直径的转子）。测试将包括根据国际标准对基准和改造后的涡轮机进行功率性能比较。
