6 FAQs about [Special blades for small wind turbines]

What is the difference between small and large wind turbine blades?

Small wind turbine blades share 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.

What is a wind turbine blade?

The blade is the main component of the wind turbine, which extracts the energy from the wind, and it contributes 20–25% of the wind turbine’s overall budget [ 34 ]. Therefore, it is essential to optimize the design of the wind turbine with a maximum power coefficient under the design conditions.

Can wood be used for small wind turbine blades?

Wood is still used as a blade material for small wind turbines in many developing countries. However, metals, which have moderate strength and fatigue properties, are not preferred for blades due to limitations associated with the manufacturing process and fatigue strength. Wood is mentioned among the materials used for small wind turbine blades in this passage.

What material is used to design a small turbine blade?

Sessarego and Wood (2015) used the property results of Shah et al. (2013) to design a representative small turbine blade. Table 13.1 shows the material properties used for blade optimization. The properties of the rapid prototyping material, ABS M-30, have been updated using a more recent data sheet.

How long does a small wind turbine blade last?

Small wind turbine blades are expected to last 20 years. The number of fatigue load cycles in small wind turbines is significant due to their higher rotational speed. Appropriate blade design and material selection is crucial for ensuring the blade's longevity.

Can a computer design a small wind turbine blade?

This paper describes a computer method to allow the design of small wind turbine blades for the multiple objectives of rapid starting, efficient power extraction, low noise, and minimal mass. For the sake of brevity, only the first two and the last objectives are considered in this paper.
