The wind turbine blade
calculator helps you design a wind turbine blade set with five variables.
- The number of blades on your turbine. The more
blades you have the slower it will turn, however the high surface
coverage allows start-up in low wind speeds and gives higher efficiency.
A good trade off is 3 blades.
- The tip speed ratio (TSR), 2 blades (9-10); 3 blades (6-8); 4+ blades (4-6). The
higher the tip speed ratio the higher the turbines rotational speed.
- Blade efficiency. 2 blades (0.30); 3+ blades
(0.35). Your efficiency is determined by your blade design as well as
the number of blades.
- Blade radius, the length of each blade
- Wind speed. It is best to use an average for
your area, but also worthwhile checking the maximum wind speeds in the
area you intend to set up.
