Let’s look at the generation possibilities above and below 11 m/s. First, consider high speed wind. And this is just a observation and not criticism, but a huge percentage of the energy blowing through a turbine rotor is lost, especially at high speed. For instance, a typical power curve shows that at about 11 m/s…
Hey! Our art director designed this. Cool
Next time you visit the Cleveland Hopkins airport, cruise down Concourse A and admire “Green Utopia,” the terrazzo art in the walkway. Then look up and see the sign that identifies the artist as Mark Rook. He’s the design and creative director of Windpower Engineering & Development, the fine magazine or website you are…
How to calculate blade tip speed, and more
Leading-edge erosion is a major cause of wind turbine blade wear. As the turbine rotor spins in the air, it hits dust, dirt, insects, hail, and more. That does not sound like much until you consider the blade tip could be spinning over 100 mph. Once the blade edge wears, water can invade, freeze, and…
