Video In this video, we’ll take a closer look at Brush’s wind turbine, which is considered to be the world’s first automatically operating wind turbine for electricity generation. The turbine was designed by Charles F. Brush in 1888 and was built on his property in Cleveland, Ohio. The wind turbine consisted of a 56-foot tower…
Bearings are parts that support and guide rotating or oscillating elements, such asaxles or wheels, and transfer loads between machine components. They offer reduced friction and therefore allow high rotational speeds while reducing noise,heat, energy consumption, and wear. No matter the model of wind turbine, bearings are often a problem in all of them. The…
You will be surprised to know that the first known wind turbines recorded in history were Vertical axis wind turbines, not the current dominant technology of horizontal axis wind turbines. This dates back to the 7th century B.C when vertical axis windmills were built on the Persian land. They were based on the aerodynamic drag…
Once the yaw ring is installed, the nacelle main frame must be turned over in order to complete the yaw system assembly. Temporary legs are installed, and fixtures are added to the yaw ring. The main frame is lifted, and one side is let down while the frame is rotated. Here you can see the…
