Extruded Aluminium Blades.  

The GE-222 blade profile has been used by wind turbine builder Windcharger for many years. Its a proven performer with good all round performance. The GE-222 profile is now available for the aftermarket wind turbine industry. The blades are available in Wood, PVC and now Aluminium.

Aluminium blades have many advantages over other blade materials, including...

  • Improved strength and rigidity.
  • Better sheer strength at mounting points.
  • Not UV affected, long life compared to PVC or wood.
  • Easier and cheaper to paint , could be used unpainted with leading edge tape.
  • More uniform airfoil.
  • Can be joined by using aligning dowels in the C channels to position until secured with rivets, allowing longer blades to be put together with the 1 meter maximum postage limit, potage is cheap compared to other freight methods.
  • End caps are held with 4 small screws.
  • By using small rod in the C channel in the ends allows easy balancing.
  • Slightly lighter than PVC.
  • 100% aluminium, recyclable.

These blades are supplied by Phill Mann of Oz Ax Wind Engineering. Price is $48.50 + GST ( AU )per meter.

If you wish to inquire about ordering a set of the extruded aluminium blades, please fill in the form below.

Like the PVC Blades, the Aluminium blades need a internal steel spar to mount and strengthen the blade. We recommend the 25-75 rule. This mean the steel tube needs to be at least 75% of the blade length, starting from the inner ( turbine center ) part of the blade, and the first 25% needs to be solid steel. See the Mounting Extruded Blades link below.
