How are wind turbine blades designed?
What factors affect the design of a wind turbine?
- The kind of blades you use and configuration of your blades may affect the design of your turbine. Old farm windmills were basically small sails attached to a rotating shaft, but wind turbines resemble giant propellers and have large teardrop-shaped blades. These blades should be sized and pitched correctly for the turbine to work efficiently.
What are the parts of a wind turbine?
- A typical wind turbine design is made up of rotor blades, a drive shaft, a gear box, a speed shaft, a generator, and support cables and casing [65,71]. Wind turbines can be horizontal-axis or vertical-axis turbine types. Two- or three-bladed turbines are usually used for electricity generation, whereas 20 or more blades are used for water pumping.
How do you make a wind turbine spin faster?
- Using an even number of blades, such as 2 or 4, makes a wind turbine more likely to vibrate as it spins. Adding more blades increases torque but can make the turbine rotate more slowly. Blades can also be made from household products, like modified shovels.

What does a wind turbine engineer do?
- • Students perform experiments and design different wind turbine blades • Use simple wind turbine models • Test one variable while holding others constant • Record performance with a multimeter or other load device • Goals: Produce the most voltage, pump the most water, lift the most weight
What are the characteristics of a wind turbine?
- Wind power devices are now used to produce electricity, and commonly termed wind turbines. turbine. A turbine with a shaft mounted horizontally parallel to the ground is known as a horizontal axis wind turbine or (HA WT). A vertical axis wind turbine (V A WT) has its shaft normal to the ground (Figure 1). characteristics.
