3DFoil results compares well with experiments from
N.A.C.A Report No. 647, 1938, Figure.[1].
We used 3DFoil to perform aerodynamic simulations for a rectangular wing based on a NACA 0012 airfoil. Results were compared with a NACA experiment performed in 1938, Ref. [1]. NACA tested a full sized wing with a span dimension of 36 feet and chord of 6 feet. The tests were performed in a full scale wind tunnel. We compared the results of 3DFoil, our vortex lattice package, against the experiments conducted on the NACA 0012 version of the wing. The results show excellent agreement between 3DFoil and the experiments for the lift and drag coefficients.

3DFoil empowers engineers, designers and students alike to design and analyze 3D wings, hydrofoils, and more. The software seamlessly blends speed and accuracy, using a vortex lattice method and boundary layer solver to calculate lift, drag, moments, and even stability. Its user-friendly interface allows for flexible design with taper, twist, and sweep, making it ideal for creating winglets, kite hydrofoils, and various other aerodynamic surfaces. Notably, 3DFoil surpasses traditional 2D analysis by considering finite wing span for more realistic performance predictions, helping users optimize their designs with confidence.
