Manufacturing defects in wind turbine blades are Dry Spots It can be dry spots and even large whitish areas, which show the lack of resin in the laminate.Glass fibers are dry because they have not been properly impregnated with resin. Excess Resin Regions with excess resin are more fragile and can crack more easily, in…
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…
Let’s take a closer look at some of the sensors used in the yaw control system. Potentiometers,encoders and ultrasonic sensors may be used to detect wind direction. A potentiometer is a variable resistor consisting of a resistive strip, 3 terminals, and a movable wiper. The movable wind vane is connected to the wiper. As the…
