Wind Turbine Blade Design
One of the oldest existing methods of energy generation is the use of wind turbines. Since they were first introduced, design aspects of wind generators have steadily improved, especially when it comes to how the blades that are responsible for turning the turbines’ rotors have been built. The main advantage of modern blade design is that it gives wind turbines the ability to generate more power from less wind now than ever before, which in turn makes it possible to use smaller and quieter turbines.
Mats made out of reeds were used as the blades for the first-generation wind turbines. Their main drawback was a lack of durability. The short lifespan of this type of blade led inventors to consider other ways of making them.
Reed blades would eventually be discarded in favor of lighter and more reliable cloth sails. Thanks to this blade design, early windmills were able to harness wind power effectively for processing grain.
The next stage in the development of wind turbines arrived with the introduction of wood blades and horizontal axis blade configurations. The impetus for the new style of turbine was the design of airplane blades, which had recently made major strides. Although much lighter, wooden blades were nevertheless able to produce much more power than previous turbine blades.
Electricity was generated for the first time from wind turbines thanks to these designs. Larger wind turbines were soon built to take advantage of these improvements, generating energy in commercial settings.
At this point, the difference between horizontal axis turbine blades and vertical axis turbine blades became that much more distinct. Generally, the shape and materials of the blades as well as the number of blades used per rotor would be the main area of variation to come for horizontal axis blades.
Thanks to their strong balance of stability and rotor speed, 3-blade designs are the standard for horizontal axis wind turbines. In most modern turbines, composite blades are used, which have great strength and flexibility in addition to being lightweight, making them excellent for both residential and commercial uses. Wind turbines with composite blades can not only spin faster, but can also generate energy from low-speed winds, which older models couldn’t do.
For vertical axis wind turbines as well, there are a number of new designs available currently, appropriate for a wide variety of applications. The rotation for these units is usually provided by features that take advantage of either the lift or drag of the wind.
The main advantage of vertical axis wind turbine designs is their capacity to generate power regardless of wind direction. Thanks to this feature, vertical axis turbines provide the most consistent output of energy of any type available right now. What’s more, as vertical axis turbines usually don’t require a tower, they’re often favored by residential users.
