In this video I show you how to 3D print the bidirectional impulse turbine to use it with the thermoacoustic Stirling engine.
If you become a member for just 99 cents you can download all 3D models and drawings of the turbine and the thermoacoustic Stirling engine directly as they are developed to print them on your 3D printer.

If there are enough members I can rent some webspace to host all files and content properly and develop the engine faster.
In order to use the pressure waves of the thermoacoustic Stirling engine, I would like to use a bidirectional impulse turbine.
A turbine offers several advantages over the piston used previously.
The origin of bidirectional turbines lies in the harvesting of energy from ocean waves but the use in thermoacousic devices was also shown in experiments.
The turbine can convert acoustic power into shaft power by redirecting the bidirectional axial flow towards the rotor blades with two sets of guide vanes.
The resulting shaft power is converted into electricity by connecting a generator to the rotor.
In the last video I asked you to help me simplify the thermoacoustic engine so that anyone could make it without a specially equipped workshop.
Thank you very much for the many very good suggestions, which I now look forward to implementing with you.
In the members area, I publish all the drawings and CAD models needed to reprint the components on a 3D printer.
The complete models of the turbine are also available for download.
The first simplification towards a thermoacoustic motor that anyone can make is to replace the existing piston with a turbine, which is much easier to build with a 3D printer.
A turbine also has other advantages:It is virtually wear-free and can be connected directly to the generator without an intermediate transmission.
A systematic test with new filament and 0.2, 0.4 and 0.6 mm nozzles shows almost perfect print quality, apart from slight warping at the tips of the turbine blades.
A friend gave me some six year old carbon fibre filament to test, but I am disappointed with its stability and layer adhesion.
Printing a brim prevents the tips of the turbine blades from warping, but is very difficult to remove with PETG.I'll have to look for better options in the Bambu slicer, or add mouse ears or something similar directly to the CAD model.
Other than that, I am very happy with the print quality and can now do my first tests with the prototype turbine.
Everything is working to my complete satisfaction on the very rudimentary test set-up.Now I just have to print a housing with guide cones and attach it to the thermoacoustic Stirling engine.
I will immediately link all the finished components as CAD files in the members area for reprinting and also add CAD drawings as soon as possible.
Thank you very much for watching, please continue to give me feedback, it helps a lot with the development of the engine!
