The wind turbine blade calculator
helps you design a wind turbine blade set using four basic variables.
- The dimensions of your
turbine measured by your blade radius.
- 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.
- Enter your 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.
- Enter the 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.
- Push the ‘Solve’ button
and the width and angle of the blade are given at different sections of
the blade, giving you a guide to build your airfoil.
