Understanding Airfoil BasicsWhat Makes an Airfoil EfficientSouth Africa's wind farms turn a steady resource into power, but the airfoil for small wind turbine dictates how much of that resource becomes electricity. Efficiency starts with lift versus drag, and the...
Upfront Investment and Long-Term SavingsAverage Purchase and Installation Costs ComparedIn South Africa, the upfront investment for a wind turbine or solar panels typically ranges from R80,000 to R250,000 depending on capacity and installation complexity. Solar...
Anatomy and Materials of Turbine WingsCore Structure and Root DesignAt the junction where a wind turbine wing bolts to the rotor hub, the root bears forces that would fatigue ordinary steel! Modern blades rely on a pultruded carbon fiber spar cap running tip to root,...
