VisualFoil is a comprehensive program for Windows aimed at engineering professionals involved in airfoil analysis and design. It provides an extensive array of features and functionalities to support the development of aerodynamic structures.

Brief review

This tool allows you to analyze custom airfoil shapes on your desktop or laptop computer. The graphical interface comprises graphs, flow diagrams, and tables that can be exported to third party software. It also includes a library consisting of NACA 4, 5 and 6 digit shapes, along with the airfoil in the UIUC database. The unique stall model predicts the maximum lift coefficient and angle attack.

Flow solvers

By relying on a linear strength vortex panel method to solve the inviscid outer flow, it is possible to perform the analysis on both Windows PCs and tablets. The utility calculates CI, Cd, and Cm for custom airfoil shapes as well as those from the UIUC and NACA libraries. Its innovative boundary layer solver accurately forecasts transition, separation, and stall.

Distribution model

Please note that the application is available through a subscription model, priced at one hundred and twenty nine dollars per year. The cost makes it a convenient choice for individuals seeking an airfoil analysis and design solution. Alternatively, you may build model aircrafts and print the components using a program called WinFIOL.
