I've "wasted" 4 months writing code that's able to automatically improve things (in this case - airfoils), and found that I'm able to create airfoils that XFoil suggests will perform 200% better than the real (existing) ones I've scanned in and compared (I've got a 3D scanner).
I'm keen to "team up" with anyone else who finds the idea of designing props interesting. In particular, I'm interested in exploring "non conventional" new ideas, improving the analysis side of things (eg: using OpenFOAM instead of Xfoil), and discussing the intricacies of the theory stuff (eg: should a each "station" of a prop blade be designed to provide the same amount of thrust? Should adjacent points on a blade try to maintain the same Re? What range of AoA's should be chosen for feeding to the particle optimiser for selecting the best airfoil?). I'm also interested to see if anyone's got ways to make and test these things? My own 3D printer is too small to mill the size prop's I'm wanting to build (125cm), but I can make smaller ones - but *testing* them is something I'm not set up to do - maybe someone else is?
