| New STAR wind blade Knight & Carver's Wind Blade Division has completed the first in a series of 27½-meter wind blades as part of a U.S. Department of Energy project. The Blade has the name 'STAR' – which stands for 'Sweep Twist Adaptive Rotor'. It is specially designed for low-wind-speed regions. Sized overall at 27½ meters x 2.4 meters, the blade takes maximum advantage of all wind speeds, including marginal speeds. Instead of the traditional linear shape, the blade features a curvature toward the trailing edge, designed to relieve pressure on the blade and turbine drive train. The blade is scheduled for static-testing at Knight & Carver's on-site test facility in San Diego during December. A second blade will be built before the end of 2006. write your comments about the article :: © 2006 Construction News :: home page |
