In wind turbines, this type of blade design uses the direct impact of the wind to drive the turbine rotation. It is suitable for use in high wind speed environments. The blade contour is simple, with a small curvature, and mainly uses wind speed to achieve efficient energy conversion.
Abstract Small wind turbine bladesshare several features with large blades but have some important differences. The two main differences are their much higher rotational speed, leading to more fatigue cycles and higher yaw moments, and their operation at low Reynolds number, which means that thick aerofoil sections cannot be used near the root.
Sessarego and Wood demonstrated the procedure for designing small wind turbine blades and optimized the design for the rapid starting, efficient power extraction, and minimal mass. They noticed that rapid prototyping has excellent potential for small blade manufacture. They used E-glass and polyester resin in the blade design.
The annual average wind speed at the location of installation is used to determine the size of the wind turbine blade required to generate the necessary power. From the preliminary analysis of airfoils that are suitable for low applications, a suitable airfoil is selected for the blade profile.
In such circumstances, small turbines with good low wind performance can efficiently extract the energy available in wind. Power generated by the wind turbine is directly proportional to
This paper presents a typical design methodology of the rotor blades of a small wind turbine with a power generation of 11 kW (rotor radius of 3.5 m). First, the design parameters were presented.
