Following on from my Makevember post yesterday, where I tried to make turbine blades, and Failed…
I fed 6050 from SG6050 into Fusion 360 and this is what it gave me:
To check it wasnt it that was broken, I ran the script with the defult value of ‘2412’ and it worked, so hmmmmm.
However… They were not the correct format for the plugin, so back to the Drawing board / CAD space.
Looking round the internet I found this Airfoil DAT to Spline tool. The instructional screencast is:
After exporting the Text in the blue ‘Dat file’ box on SG6050 page and pasting it into a text file (I have called it ‘SG6050.DAT’ (The uppercase DAT is important)), and running the tool:
Now by adjusting the cord length and then extending the trailing edge till they intersect I will try to make my blade following Michael’s design:
Hmmm, now those of you playing along at home will spot a problem with that plan… the above drawing does not contain enough information, it was a good enough reference when I was tracing, however it doesnt work now I am using the generator.
So Plan B
I found Peter J. Schubel and Richard J. Crossley’s “Wind Turbine Blade Design” document, and looking through to Figure 8 gives me a good starting point:
Luckly The Aeronautical Research Institute of Sweden have produced a big book of all the FFA-W1, W2, and W3 (FFA TN 1990-15 v.1-2 c.1) series of airfoils which has the FFA-W3-301, and Github has DU93-W-210.
The plugin complains my file format is wrong. So at this point I am going to give up again 🙁 but I can try again soon.
