Overview

VisualFoil NACA is a modern easy-to-use airfoil analysis and design software for Windows XP, Vista & 7.  The NACA Version is suitable for most users who need to analyze and obtain data for NACA 4, 5, & 6-digit airfoil shapes.

VisualFoil can quickly and inexpensively determine the best cross section shapes for  wings, spoilers, struts, hydrofoils, keels, rudders and other aerodynamic and support structures.

Feature of VisualFoil 5 Include:

• Incompressible flow solver using vortex panel method coupled with boundary layer solver for computing lift, drag and moment coefficients.
• Built-in library of NACA 4, 5 & 6-digit airfoils
• Computes and graphs Cl, Cd & Cm versus angle of attack.
• Stall model to predict the maximum lift coefficient and angle of attack for maximum lift.
• Built-in graphs
• Built-in tables
• Export tables to .csv files
• Export airfoil to .dxf files
• Airfoil plotting

Note:  The NACA version of VisualFoil 5.0 does not read-in custom airfoils & .DXF files.  It will analyze and modify NACA 4, 5 & 6-digit airfoils and generate lift, drag and moment coefficients. It can export and plot these airfoil shapes.  The price is only $69. Buy NACA Version ($69).

Flow Solver

• Linear strength vortex panel method
• Coupled boundary layer solver to compute profile drag.
• Lift, drag & moment coefficient calculations.
• Prediction of transition & separation points to demonstrate the validity of your calculations.
• Stall & maximum lift prediction
• Surface graphs of pressure  coefficient & velocity ratio for clear explanations of the boundary layer behavior.
• Beautiful color contour graphs of the pressure coefficient for your reports and presentations.
• Custom graphs of Cl, Cd & Cm versus angle of attack that you can use in your homework assignments and final reports
• Multiple graphs of Cl vs Cd for explanining why you picked one airfoil over the other.
