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 analysis based on the Lifiting Line Theory and the Vortex Lattice Method
Aspect Ratio influence
Comparison of XFoil results to finite wing analysis results
Plane Design
Streamlines display
Questions about xflr5, bug reports, suggestions for enhancement should be directed to the Open Discussion Forum
