Summary

VisualFoil Plus is used by engineers and designers to compute 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. The software can analyze and select airfoils for aircraft, water craft, industrial machinery and other products. VisualFoilPlus produces graphs of lift, drag and moment coefficient versus angle of attack; surface pressure coefficient, velocity, Mach number and temperature. The software produces contour plots of pressure, Mach number, temperature and total pressure. VisualFoil Plus has a large library 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.

Benefits of VisualFoil Plus include:

• Understand the behavior of airfoils used in the design of wings, helicopter blades, hydrofoils, fans, propellers and other equipment.
• Reduce testing time and cost associated with high speed wind tunnels. VisualFoil's easy-to-use compressible flow solver tests airfoils in the transonic and supersonic flow regimes.
• Enter and immediately analyze existing blade cross sections directly from your .DXF drawings
• Understand and make critical design decision in transonic & supersonic flow regime.
• Get a full CFD package that includes CAD input, grid generation, CFD solver and post processing tools. This is all done on your existing Windows PC.
• Eliminate steep learning curve for new engineers & reduce training costs.
• Share airfoil data & results across your entire department
• Easy-to-use tool for designing more efficient wing & machine blade cross-sections.
• Windows based interfaces requires little or no training.
