    Aug 23, 2017Mitigating loads on a wind turbine rotor can reduce the cost of energy. Sweeping blades produces a structural coupling between flapwise bending and torsion, which can be used for load alleviation purposes. A multidisciplinary design optimization (MDO) problem is formulated including the blade sweep as a design variable.

  • Wind Generator

    • Always stand upwind when near the wind generator to avoid fly-ing debris in the event of failure. • Unless your wind generator is unconnected and lying on the ground, it must be connected to a battery or other electrical load. Otherwise, the blades can spin freely and, in a high wind, attain dangerous speeds.
