Wind turbine blades are mostly aerodynamic profiles that look and function in much the same way as aircraft wings. This article will discuss the three main elements of the blade, which determine the shape and size of the blades of wind turbines.
1. The diameter of the propeller: The diameter of the propeller is the diameter of the circle that the propeller observes when it rotates in air. The size of the propeller is measured mainly by its full diameter. In combination with the shape of the blade, increasing the diameter of the propeller usually also increases the surface area on which the wind can affect. As a rule, the larger the propeller, the more power a turbine can produce.
2. Blade rupture: camber is a different amount of curvature of the front and rear sides of the propeller blade. The shape of the front of the blade is different from the shape of the back. The goal of the collapse is to help cause a difference in speed between air masses moving on opposite sides of the blade, thereby increasing the (air) pressure difference between the two sides (front and rear). The pressure difference makes the propeller rotate.
3. Blade length: the chord length is basically the width of the blade, measured from the front to the rear edge of the propeller. Usually, the wider the blade (longer than the chord length), the greater the surface area of the blade. Note that the chord length (blade width) may increase or decrease along the longitudinal (sleeve to the end) blade length.
