Everyone loves turbojet engines (except for Green Peace), so why not put one in your garden? Large blades at the front create movement from the wind, while the internal HPT blades (thanks Linus3D!!!) spin to replicate the movements within a turbojet engine. Uses a ¼" wooden dowel.
Assemble the HPT blade sections onto the shaft, and slide it into the engine housing. Then, attach the front support to keep it in place. Attach the blades into the blade hub, then attach the hub onto the front of the shaft. Then attach to wooden dowel and let 'er rip!
The author remixed this model.
I used the High Pressure Turbine blades to create a neat center for the inside of the engine.
