This picture presents a wind tunnel I have built for testing and measurement of low Reynolds number systems. We can see here the fuselage of the Cauzy plane, which has been the basis for the design of a model plane which is now finished.

I now intend to measure polar of common and experimental airfoils by getting Cx/Cz values versus incidence angle. This could help me to design more performant model gliders and contribute in a very modest way to perhaps some particular improvements of laminar airfoils, typically similar to Selig airfoils behaviours.
