64 panels, and the pressure is right nearly everywhere

The surface pressure coefficient from 64 cosine-spaced panels, drawn over the exact distribution from the conformal map. Suction is upwards, which is the convention everywhere this quantity is plotted. The two are indistinguishable over most of the section and part company at the leading edge, where the pressure changes fastest and each panel is averaging over the steepest part of the curve. The lift, being an integral, is much better than the worst point on this figure: it is out by 0.45 per cent.

1 essay calls panel-solve. The drawing above is what it returns with no arguments at all; every call below passes it something, because a placement that passes nothing draws whichever member of the family the generator happens to default to rather than the one its essay argues about.

It is also the blast radius. Changing panel-solve changes every figure listed here at once, and on this site it may change what they assert as well as what they show — which is what has to be rebuilt and looked at before the change is believed.
