A Leitwind turbine blade. Rotor blades, like aircraft wings, are essentially cantilevered beams with lift-generating surfaces. Early blades were made of wood. More recently, they are manufactured of fiberglass and epoxy resins by reaction injection molding in rather complex equipment. The quest for greater power will demand longer blades …

Gears & Gearboxes 101. A gearbox is typically used in a wind turbine to increase rotational speed from a low-speed rotor to a higher speed electrical generator. A common ratio is about 90:1, with a rate 16.7 rpm input from the rotor to 1,500 rpm output for the generator. Some multimegawatt wind turbines have dispensed with a gearbox.

(2.4), the power of the wind is a linear function of air density and as a result of the limited range of air density fluctuations, the density is of secondary importance. The power dependence on the area implies a nonlinear quadratic dependence on the radius of a wind turbine swept area, highlighting the advantages of longer wind turbine blades.

A typical wind turbine blade design involves a hollow aerodynamic profile comprised of two outer shells, bonded together using adhesives and supported by one or more load-carrying shear webs (Jensen and Branner, 2013). A wind turbine blade is composed of around 60% reinforced fibres (typically glass), 23% thermosetting polymer …

Introduction.

A wind turbine is a device that converts kinetic energy from the wind into electrical energy. The most common type of wind turbine uses a rotor to capture the wind's kinetic energy and turn it into rotational energy. This rotational energy is then converted into electrical energy by a generator. Wind turbines have been around for centuries ...

2.3 Small Wind Turbines. Small wind turbines are defined by IEC [ 12] as a wind turbine with a rotor swept area no greater than (200, mat {m}^2). Therefore the diameter is limited to 16 m. However, most of them have much smaller diameters starting at about 1 m. More can be found in [37], Chap. 9.

The Savonius wind turbine is a simple vertical axis wind machine invented by Sigurd J. Savonius in 1922. In its original design, it was made with two half-cylindrical blades arranged in an 'S' shape. The convex side of one half-cylinder and the concave side of the other face the wind at the same time as shown in Figure 26.

The rotor blades capture the wind and transfer its power to the rotor hub. On a 600 kW wind turbine, each rotor blade measures about 20 meters in length and is designed much like the wing of an aeroplane. The movable blade tips on the outer 2–3 meters of the blades function as air brakes, usually called tip brakes.
