General description

XFLR5 is an analysis tool for airfoils, wings and planes operating at low Reynolds Numbers. It includes:

  1. XFoil's Direct and Inverse analysis capabilities
  2. Wing design and analysis capabilities based on the Lifiting Line Theory, on the Vortex Lattice Method, and on a 3D Panel Method

Questions about xflr5, bug reports, suggestions for enhancement should be directed to the Open Discussion Forum
