FOIL Release Description

FOIL Release is a CAD program designed to help you decide the foil shape or type that you must use for your boat design. By using this program you can view which foil is least likely to stall when used as a rudder and avoid making the wrong choice. The program is using B-splines to define shapes and the proven NASA code (Known as the Eppler Code) for performance prediction. Main features: Symetric or Cambered Foils Spreadsheet Data Editor for reference foil offsets Calculate Lift, Drag, Turbulence and Separation, Lift to Drag Ratio, Area Coefficient, Relative Velocity, REYNOLDS Number, Bubble Formation Analyze TRIM TABS effect on LIFT/DRAG etc. Calculations at 5 Reynolds Numbers and 13 Angles of Attack Scale overall foil thickness Use Existing NACA or NASA foils as References or starting point to design a new foil Foil fairing using slope and curvature curve plots. Auto-Fit NURB splines to existing foil data High Quality Printed Reports and Plots. Capture Performance plots as BMP graphics files. Calculates 48 Offset Values (NACA provides only 26) Calculate foil performance over Reynolds Numbers between 250,000 and 10 million Output TXT- Eppler Format, DXF, CDL, or IGES NURB CAD for precision CNC applications in additiuon to printingall offsets and physical characteristics. Export design files to WINGS and LOFT for complete design capability
