Paul,

The Ryerson Aero Design Team is proud of that airfoil. The S45A-3 definitely has a lot of camber and one of the added benefits with that airfoil is the depth that allows one to build a very robust structure at a reasonable weight. Truth be told, I used the Ryerson S45-A3 on the previous Aero Design entries (2000 & 2001 A.D. East) that I designed, but for 2002 I broke from tradition to try the Selig 1223 on “Solution”. Our other team “Freestream” stuck with the S45A-3 airfoil. That is the wingtip of their aircraft that you have on your post. For first timers, they did an excellent job.

I have the co-ordinates for the airfoil, but in all fairness to this year’s team, I will want to check with them first. I’ll let you know when I get an answer.

BTW, the airfoil name comes from the room number of one of the Professors at the University - S45A. The 3 was the third iteration.
