Re is for a 100mm chord

I'm guessing XFOIL will do this.

Well, I now have XFOIL, and the very useful matlab interface.

But sadly xfoil is no good for the ridiculous alpha figures, although having said that my rotor design doesn't use ridiculous alpha so i should be ok

Greg,
If you're still after some high AoA figures, you can explore the subject of wind turbines a little and find data for common airfoils at ALL angles of attack.
Particularly the NREL that tried a few concept VAWT turbines back in the 70's. The reports are "googlable" but if your searches turn up dry, I have links and PDF's at home.
