Sounds like an airfoil for the SAE heavy-lift competition to me...

Hey Brian, don't know if you're an Aero major or not, but if you were, you'd know for every airfoil there is a purpose, and their purpose might be best fulfilled with what they have picked. As for the coefficient of moment number, it IS really important that they have it for what they're designing..

Hey Frank, if it is for SAE, what school are you competing for? I'm from Mississippi State and we'll be competing for the first time this year. Oh, and as for the XFOIL data - don't take it for absolute - we've got the Selig books with that data in it, and they say that XFOIL overshoots some of CL values at such a low Re. Something to keep in mind.
