XFLR5 - airfoil analysis at low Reynolds Numbers

Click on the image for a larger resolution.

I am currently working on a new flying wing design. I was extremely amazed that there is open source software for doing software based wind tunnel simulation. The software package is called XFLR5 and is available as source package and binary package for windows (the debian repo includes a binary as well: apt-get install xflr5).

The animation above shows a flying wing design I am working on. The wing uses an MH-64 airfoil. In the animation you can see the induced drag, the lift and wake turbulence created by an Angle of Attack between -3 up to 12°.
