Planform, a Flying-Wing Designer with a Center-of-Gravity Problem to Solve
An interactive tailless-aircraft tool for drawing wing planforms, blending NACA airfoils in 3D, checking MAC and CG, and exporting an STL or design sheet.
Field notes
The tool combines a 2D wing planform editor with a 3D loft that blends standard NACA 4-digit root and tip sections, then applies spanwise twist and dihedral. Its calculations include MAC and CG percentages from exact spanwise integration, while the planform marks a 10–25% local-chord reference band. Users can include a tapered center-body, inspect stations, and export the resulting geometry as STL or a design sheet.
