In this work a 2D CFD solver has been used
to optimize the shape of a leading edge slat
with a chord length of 30% of the main airfoil
which was 40% thick. The airfoil configuration
was subsequently tested in a wind tunnel
and compared to numerical predictions. The
multi-element airfoil was predicted to achieve a
Cl−max of 3.1 based on the main airfoil chord
length, which was confirmed in the wind tunnel
campaign. Using wake rake traversal and
wool tuft flow visualization wall interference effects
were investigated, which were found to
be a source of considerable uncertainty when
measuring on thick airfoils.
