![]() It prints in 2 halves and joins like this:. Wind turbine blade, 45cm, 1400RPM in 13kt flow River turbine (back view) - 40cm dia, 1m/s flow rate, 120rpm Right now, it does airfoil and hydrofoil wings, struts, and so far it partially supports two types of turbines (ducted and free). Underwater Glider, with makeshift nose-weightĪirfoil-Tools is still a work-in-progress. I 3D printed this, and it "sails" about 75% of my pool length - it would certainly do 100% if I could find a sinker to fit the slot (I used what I could find - a nut - so - lots of unwanted drag). Screenshot in the process of making an underwater glider Here's a screenshot - In this example, I "revolved a strut" to make a low-drag fuselage, added wings and two more struts for the tail, and hollowed out a spot to insert a sinker (it's an underwater glider). I've included a database of 768 base foil shapes (excellent lift with low drag) which cover 64 representative Re's and 12 flow regimes - each shape being the result of thousands of CPU-hours of particle-swarm/genetic optimisation work, plus another 768 base strut shapes (low drag only). In a nutshell - you tell it what you're doing (in easy everyday terms) and my add-in will insert the best shape for what you need. This is a free Fusion360 UI front-end to my 8-or-so years of research into foil optimisations. Hey all! Autodesk just published my new add-in.
