Sandia researcher Todd Griffith is designing a 200-meter blade for a 50Mw offshore turbine.
Sandia’s design for the Segmented Ultralight Morphing Rotor, a low-cost 50 Mw offshore turbine that uses
200-meter blades, could significantly increase offshore wind power performance in the United States and the world. The design, which was created as part of the Department of Energy’s Advanced Research Projects Agency-Energy program, will capture more energy than conventional turbines. The rotor’s load alignment reduces the mass required for blade stiffening, allowing the turbines to withstand severe storms. Additionally, the massive blades can be manufactured in segments, which reduces manufacturing, transportation, and assembly costs.

Sandia has developed a series of detailed 100-meter blade reference models that are available to designers and researchers for design studies and cost analysis. The available models include an initial baseline design using glass materials and conventional airfoils. A final, slightly lighter, reference design with carbon fiber, an updated core strategy and flatback airfoils is also available.
