Sandia’s 100-meter blade is the basis for the Segmented Ultralight Morphing Rotor (SUMR), a new low-cost offshore 50-MW wind turbine. At dangerous wind speeds, the blades are stowed and aligned ...

NREL researchers, funded by the US DoD, leverage 3D printing and thermoplastics to produce wind turbine blades.

15-23 (9 pages) Abstract: Wind energy is ... axis wind turbine. Blade geometry is obtained from the best approximation of the calculated theoretical optimum chord and twist distribution of the ...
