General description
XFLR5 is an analysis tool for airfoils, wings and planes operating at low Reynolds Numbers. It includes:
- XFoil's Direct and Inverse analysis capabilities
- Wing design and analysis capabilities based on the Lifiting Line Theory, on Vortex Lattice Method, and on 3D Panel Methods
Questions about xflr5, bug reports, suggestions for enhancement should be directed to the Open Discussion Forum
