High Lift S1223
Dec 7, 2005

The S1223 airfoil which has been used in the SAE AeroDesign
Competition has been retested at UIUC to obtain the pitching moment
data.  The results shown below are preliminary and subject to change
upon final data reduction.  Thanks go to Yvan Tinel for making the
wind tunnel model. These data will be included in Vol 5 or 6 of the
airfoil data series books.  More data on the S1223 is included in
other volumes: here
