This Small Business Innovation Research (SBIR) Phase I project intends to eliminate the transportation problem faced by large wind turbine blades for land-based wind farms. Transporting blades by truck constrains their size to a limit that falls somewhere between standard dash 50m-60m, due to roadway length, height and weight limitations. If blades over this transportation limit were available for use at land-based wind farms, larger turbines could be used, lower class wind sites would be opened for development, and capacity factors could be increased using existing turbines. This SBIR Phase I project will further develop a modular blade tooling concept that will allow continuous blade spars of 100m or more to be produced on-site at wind farms thus eliminating road transportation issues. This tooling concept encompasses an array of logistical improvements that optimize the effectiveness of this on-site approach. The unique manufacturing method allows superior integration of the structural components of the blade, producing a more robust product that is not susceptible to typical blade failure modes. During this Phase I feasibility will be evaluated "across three major areas: Manufacturing Methodology,Structural and Dynamic Performance, and Logistics and Cost Modeling.The broader impact/commercial potential of this project will be to reduce the cost and therefore increase the penetration of wind power. Wind turbine power output increases with the square of the blade radius. Offshore turbines (in the 5MW to 7MW range) use blades that are 60m to 80m in length. If transportation was not an issue for land-based turbines, these turbines would continue to scale in capacity with their offshore counterparts. Longer blades would also allow for the development of lower class wind sites with currently available turbines increasing the penetration of domestic renewable energy. Additionally longer blades would allow an increase in capacity factors for currently available turbines lowering their cost of energy, a topic of critical importance to wind project developers. Blade manufacturing at the wind farm will create local jobs. Although a 100m blade tool may be transportable, its logistics pipeline is large and will still require local transport and all the supply chain logistics of large scale production. However, instead of all this being done out of state or out of the country and then transported to a US farm, a large portion of the blade manufacturing work will occur at the turbine site.

该小型企业创新研究（SBIR）第一阶段项目旨在消除陆上风电场大型风力涡轮机叶片面临的运输问题。由于道路长度、高度和重量的限制，通过卡车运输叶片将其尺寸限制在标准仪表板50 m-60 m之间的某个地方的福尔斯。如果超过该运输限制的叶片可用于陆基风电场，则可以使用更大的涡轮机，将开放较低等级的风电场进行开发，并且可以使用现有的涡轮机来增加容量系数。SBIR第一阶段项目将进一步开发模块化叶片工具概念，允许在风电场现场生产100米或更长的连续叶片翼梁，从而消除公路运输问题。这种工具概念包括一系列物流改进，优化了这种现场方法的有效性。独特的制造方法允许叶片的结构部件的上级集成，从而产生更坚固的产品，该产品不易受典型叶片故障模式的影响。在第一阶段，将在三个主要领域评估可行性：制造方法，结构和动态性能，物流和成本建模。该项目的更广泛的影响/商业潜力将是降低成本，从而增加风力发电的渗透率。风力涡轮机的功率输出随叶片半径的平方而增加。海上涡轮机（在5 MW至7 MW范围内）使用长度为60米至80米的叶片。如果运输不是陆基涡轮机的问题，这些涡轮机将继续扩大其海上同行的容量。更长的叶片还将允许利用现有的涡轮机开发较低级别的风力发电场，从而增加国内可再生能源的渗透率。此外，更长的叶片将允许增加现有涡轮机的容量系数，降低其能源成本，这对风力项目开发商来说是一个至关重要的话题。风电场的叶片制造将为当地创造就业机会。尽管100米的刀片工具可以是可运输的，但其物流管道很大，并且仍然需要本地运输和大规模生产的所有供应链物流。然而，代替所有这些都在州外或国外完成，然后运输到美国农场，大部分叶片制造工作将在涡轮机现场进行。
