VisualFoil Plus solves the 2D compressible Euler equations and computes the lift, drag and moment coefficients for airfoils in subsonic, transonic and supersonic flows. It generates accurate aerodynamics data for experimental or existing airfoils where the information might be incomplete or unknown. VisualFoil Plus analyzes and selects airfoils for aircraft, water craft, industrial machinery and other products. VisualFoil Plus has a library of 1000s of built-in airfoils which includes NACA 4, 5 & 6-digit airfoils. In addition, the user can enter custom airfoils for analysis and modify existing airfoil shapes.
A poorly performing airfoil will result in a poorly performing wing. If you are designing a wing for a UAV, light aircraft, or car, VisualFoil will provide the absolute best start for your project. The same is true for keels, rudders and hydrofoils.High endurance, range and speed capabilities demand high performance airfoils. VisualFoil Plus can be used to airfoil drag divergence for propellers and high speed aircraft design.
Visual Foil Plus can be used to compute the drag divergence Mach number for any airfoil shape using subsequent runs over a range Mach number. The above figure shows drag divergence for a NACA 0012 airfoil at zero angle of attack.
VisualFoil Plus requires a PC, Laptop or tablet running MS Windows XP, Vista, 7, 8 or 10. The annual subscription cost is $395 per year.
