Tutorial on drawing wind turbine blades

How to draw a wind turbine?

By following the simple steps, you too can easily draw a perfect Wind Turbine. 1. Begin the wind turbine outline by drawing a round shape. This is the hub or center of the windmill. Then, extend three curved lines from the hub. Double each line back upon itself to outline the blades. 2. Below the turbine, draw parallel straight lines.

Why is wind turbine blade design important?

Wind turbine blade design is crucial in order to make a wind turbine work as per the expectations. Innovations and new technologies used for designing wind turbine blade have not stopped here, as new formulas and designs are being considered to improve their performance, efficiency and power output daily.

How do wind turbine blades work?

It’s obvious to say that these propeller like wind turbine blade designs convert the energy of the wind into usable shaft power called torque. This is achieved by extracting the energy from the wind by slowing it down or decelerating the wind as it passes over the blades.

Are wind turbine blades more efficient?

But wind turbine blade manufacturers are always looking to develop a more efficient blade design. Constant improvements in the design of wind blades has produced new wind turbine designs which are more compact, quieter and are capable of generating more power from less wind.

How is a turbine blade designed?

The turbine blade design is guided perhaps most strongly by the flapwise bending moments. From (Manwell, McGowan, & Rogers, 2002), this moment is defined by where T is thrust, B the number of blades, and R the radius of the turbine blade. The thrust coefficient (and from it, thrust) is a function of the axial induction factor a, and is defined by

How to reduce drag on a wind turbine blade?

Drag is essentially the friction of air against the blade surface. Drag is perpendicular to Lift and is in the same direction as the air flow along the blade surface. But we can reduce this drag-force by bending or twisting the blade and also tapering it along its length producing the most efficient wind turbine blade design.
