The Segmented Ultralight Morphing Rotor (SUMR) is a state-of-the-art extreme-scale wind turbine project capable of capturing 13MW of power. Using a downwind, 2-bladed, and coned rotor, blade lengths reach an excess of 100-meters in length. To experimentally test the turbine, a 20% gravo-aeroelastically scaled rotor is installed at the National Wind Technology Center to test the viability of such turbines.

These Giant Wind Turbines, Inspired by Palm Trees, May Be the Future of Renewable Energy
