A new design for 200 meters long blades for offshore wind turbines | JEC CompositesSandia National Laboratories’ research on the extreme-scale Segmented
Ultralight Morphing Rotor (SUMR) is funded by the Department of Energy’s
(DOE) Advanced Research Projects Agency-Energy program. The challenge:
Design a low-cost offshore 50-MW turbine requiring a rotor blade more
than 650 feet (200 meters) long, two and a half times longer than any
existing wind blade.
