Wind Turbine Model 2.3 Meter height

Wind Turbine Model to the scale of 1:100

• Hub height 1,4 m
• Total height 2,3 m
• Rotor diameter: 1,8 m

The model is fully functional with 3 degrees of freedom.

1. Yaw (with roller bearings)
2. Rotor rotation (with roller bearing)
3. Pitch (via strong magnets)

The model can be disasembled in to 5 parts with the blades of 0.87 m as the longest part.

The tower has a thread in the middle in order to make transport easier. There is also a thread at the bottom and a tower mount which can be bolted down to a plate with two M8 bolts and nuts.

The magnets are getting press fitted into the hub and the blade ends and allow full pitch adjustment and easy disassembly.

Assembly

1. The tower sections with the threads are on a seperate build plate. Play around with your settings in order to make them fit nicely. A small layer height is key to make the threads work.
2. Print nacelle and fit bearings. Remove the support thoroughly. Now press in two of the 30 mm bearings.
3. Print the top tower section (section 7). Press fit first the smaller 22 mm bearing into the bottom. Than the 30 mm bearing on top.
4. Print the spinner.
5. Print the shafts. Try to fit them into bearings and spinner. They should be fitting tight in there. If it doesnt fit adjust the size by scaling. Printing ABS with 10% cooling can be tricky. Take your time and get it fit nicely.
6. The Yaw shaft is suppposed to be press fitted into the nacelle. If it is not holding tight help with a little bit of glue (epoxy)
7. Before assembly press the magnets into the spinner.
8. Assemble the top tower section, the yaw shaft, the nacelle and the spinner. 
9. Print all other tower sections and the connection pins. Glue them together with epoxy. The connection pins help with the aligment.
10. Print all blade sections and the connection pins. Glue them together. The connection pins help with the aligment.
11. Press fit the magnets into the blades. Pay attention that the magnets are in the right orientation. Otherwise they will counteract each other.
12. Print the cooler and glue it onto the nacelle.
13. Print the tower bottom mount and screw it onto a wooden base plate or something similar.
14. Assemble everything and smile at the really nice model.

Transparency hint:

The original turbine was developed in the wind energy engineering master program of the university of applied science Flensburg (Germany) in 2025. This is the down scaled model for the final project presentation.
