Meer informatieIntroduction to wind turbine blades
Rotor blades, like aircraft wings, are essentially cantilevered beams with lift-generating surfaces. Early blades were made of wood. More recently, they are manufactured of fiberglass and epoxy resins by reaction injection molding in rather complex equipment. The quest for greater power will demand longer blades which as led designers to examine …

Wind Turbine Blade Length. Forty years ago, wind turbine blades were only 26 feet long and made of fiberglass and resin [3]. Today, blades can be 351 feet, longer than the height of the Statue of Liberty, and produce 15,000 kW of power. Modern blades are made from carbon-fiber and can withstand more stress due to higher strength properties.
