The ideal laminar flow airfoil is the combination of the Wortmann FX-62K-131 and the FX-60-126. I know this because those are the airfoils that Gerhard Waibel used, at different spanwise locations, on the best all-around racing glider ever built :)

Prosthetic wings secret project targets Cl 2 for a Reynolds about
1 Million. I am looking at slight reflex and rounded pressure map.
Second half is very thin, approximately a membrane. It does not
have a reduced drag mode, Maneuvering speed is low, 3/2 above
stall. A to B, if B is not far from A and you do not have to be there
at a certain time. Ideal for thicis about safe flying controls mostly.

skeatesy, without trying to be snarky, you are describing in few words a specific discipline within aerodynamics to which some people devote their lives. There is no "ideal" airfoil, or to put in another way, there are a nearly infinite number of ideal airfoils, each one perfect for one specific set of conditions. A more useful discussion would be to frame a specific use and then ask what airfoils would be good for that application.

what is the ideal aerofoil ... laminar flow ... equal pressure at the entry as the exit ... forward camber and rear thickness ... and what realy is praticle to achieve and how critical ... or just a general foil thats good enough across the board ...

Well,looking at the picture,and useing the teeny
bit of airfoil knowledge I have,it looks like the airfoil you have shown would have laminar flow
way way back on the wing up to the sudden and very abrupt seperation and huge turbulent drag bubble.

Let say, an airfoil (a set) for a microlift 12 mètres sailplane, with a rectangulaire planform ans a 30 niches chord. If that mate sens, hat would be your suggestions.
Thanks

I would copy the Greg Cole airfoil on the Windward Performance SparrowHawk.
