VisualFoil 5.0 for Airfoil Analysis and Design

VisualFoil 5

The airfoil shape sets the performance of your wing (or hydrofoil). An airfoil poorly chosen for its role will result in a poorly performing design. The airfoil shape is primarily responsible for range, endurance, pitching moment and other parameters related to stability and flying qualities. It is the secret to flight.

VisualFoil is a modern easy-to-use airfoil analysis and design software for Windows XP,7,8 & 10. VisualFoil quickly and inexpensively determines the airfoils for superior performing wings, spoilers, struts, hydrofoils, keels, rudders and other aerodynamic and support structures.

VisualFoil takes just seconds to analyze and compare the performance of airfoils. It is based on a linear strength vortex panel method coupled with it a boundary layer solver. It has the following features:

Airfoil Analysis and Design Software


VisualFoil 5 enables you to analyze your custom airfoil shapes on your Windows PC/Laptop. It also has a built-in library of NACA 4, 5 & 6-digit shapes and the airfoil in the UIUC database. The unique stall model predicts the maximum lift coefficient and angle of attack for maximum lift. The user interface features graphs, flow diagrams and tables that can be copied to other Windows software (such as MS Word Excel).

Flow Solvers

VisualFoil 5 is based on a linear-strength vortex panel method to solve the inviscid outer flow. This enables fast analysis on Windows laptops and tablets. The novel boundary layer solver accurately predicts transition, separation and stall. The program computes Cl, Cd and Cm for your custom airfoil shapes in addition the UIUC library and NACA 4, 5 and 6-digit airfoils.


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.
