3DFoil is based on a vortex lattice method coupled with a boundary layer solver. The software accurately computes lift, drag, moments and stability derivatives for wings, hydrofoils and other lifting surfaces. The above tutorial shows how the software is used to design and analyze a flying wing UAV. Please click here for more information about 3DFoil.
3DFoil requires a PC, Laptop or tablet running MS Windows XP, Vista, 7, 8 or 10. The subscription cost of the 3DFoil version is $40 per month or $229 per year.
