Turbine Blades
A step by step guide to making our wind turbine blades
Mould
We started of by making a mold. This was done by taking a piece of MDF and cutting/sanding it to the the desired shape.
Fill With Polyfiller
The mold is then filled with polyfill so the concave part is 'filled'. This allows us to vacuum form the shape.
Vacuum Forming
The mold is then placed in the vacuum formed. The desired thickness of plastic is chosen, heated, and the shape formed.
Cut Out Shape
The blade is accurately cut out using a craft knife.
Sanding
The blade is then sanded off and completed. It is ready to be attached to the axis.
Repeat
This is repeated as many times as is needed. We used three blades.
