Knight & Carver Builds First STAR Blade

11 November 2006

Knight & Carver’s Wind Blade Division has completed the first in a series of 27.5-metre wind blades as part of a US Department of Energy project.

With the name STAR, which stands for “Sweep Twist Adaptive Rotor, the blade has a gently curved tip which is specially designed for low-wind-speed regions.

Sized overall at 27.5 metres (approx. 90’2”) x 2.4 metres (approx. 7’8”), Knight & Carver say that the blade takes maximum advantage of all wind speeds, including marginal speeds. The blade features a curvature toward the trailing edge, designed to relieve pressure on the blade and turbine drive train.

“Depending on the wind farm’s site, this blade will capture between 5 and 10 percent more energy,” said Gary Kanaby, Knight & Carver’s Blade Division Manager. 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 the year.
