VisualFoil 5.0 for Airfoil Analysis and Design

VisualFoil 5

Airfoils are the cross sectional shape of wings, keels, rudders, propellers, wind turbine blades, struts and anything that is aerodynamic. They are 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 can quickly determine the airfoil to optimize your aircraft performance.

Increased Flight Endurance

Maximum Range

Increased Lift

Reduced Drag


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.
