Core (Foam) Structural Used as reinforcement of “sandwich” composite materials, as it is rigid, light, and highly durable.It has been used in the composites industry for over 45 years in the manufacture of boats, planes, trucks, automobiles, wind turbine blades, building panels, etc. PET Foam (Polyethylene Terephthalate) It can be found in virgin or recycled…
Video: Wind Turbine Yaw System Introduction The wind turbine yaw control system provides two functions that are crucial to safe and efficient operation: The nacelle must point directly into the wind for maximum efficiency. Also, a rotor disk that is not perpendicular to the relative wind experiences higher loading on the portion of the disk…
Electromagnetism Fundamentals Electric Charge The most fundamental quantity in electricity is electric charge. Energy transfer is accomplished by the motion of charge. Circuit In electricity, the path through which charge flows is called a circuit. Current The rate of motion of charge in a circuit is called current. The unit of current is the ampere…
Video : Wind Turbine Yaw Movements and Gyroscopic Forces Under normal operational conditions, yaw movement may occur when the rotor is stopped or when it is turning. When the rotor is stopped, the force applied by the yaw drive needs to overcome only the inertia of the nacelle and the frictional forces at the yaw…
