How does the new home wind turbine blade impact its performance?

A home wind turbine is the next generation gadget to utilize wind energy in producing electricity. Over the decades, the market for home wind turbines has remarkably developed in the global electricity market. This success rate has been achieved simply by developing matured technology, which has improved the work efficiency of the home wind turbines. The modern time turbines are relatively quiet, dependable, cost-effective and commercially competitive. This has made the wind power to be recognized widely as an important source of renewable energy. One of the vital features of the wind turbine is the blades. The shape and size of the blade determine the work power of the turbine. We are going to emphasize this matter more elaborately.

Significance of the blades

People are turning towards home wind turbines when they think about small scale renewable energy systems. The blades of the domestic turbines play an important role in its performance. Modifications have been made to the new designs of the blades to increase the wind energy conversion rate. The tip of the blade contributes to the aerodynamic performance and reduction of the vibrations and noise. For elevating the efficiency of the turbine the blades are optimally designed with the pitch control system so that the blades are set on the best angle to the wind. The wind is an unpredictable source of energy as it constantly changes in direction and strength. Therefore, a well-engineered blade is the key element of the turbine’s functionality.

Should the blade of a turbine be flat or curved?

This is a common dilemma in the minds of the people regarding the blades and is a debatable issue. Flat blades are a primitive design and have been in use since thousands of years ago, though this broad flat shape is becoming less popular now. When the flat blades push against the wind, the wind pushes it with full force and the rotation becomes slow which leads to less power output. However, they are cheap and very easy to understand and require fewer skills to design it.

Curved blades, on the other hand, have air flowing around it with the movement of air over the curved top of the blade making a low pressure on the top of the area resulting in aerodynamic lifting forces that allows the movement. The forces are perpendicular to the upper surface of the blade which causes the movement of the blade around the central hub. The curved blade allows the tip of the blade to move faster and therefore increases the efficiency in generating power.

What has improved in the new advanced blades?

The modern computer modeling techniques have been used to study the airflow around the new blades. This has allowed the technicians to estimate the power production of the turbines and they were able to come up with an improved design of the pitch control system of the blade. The new blade design has improved the performance, aesthetic feature and reduced the cost of manufacturing the turbines.

Domestic wind turbines are gaining grounds in terms of popularity and growth rate, which in turn has made them cost-effective. Check features of the blade for the best performance level.
