NACA airfoil
(OP)
Hi
I know a little about NACA nomenclature but I am having trouble with the following airfoils can anyone help explain what the numbers mean.
NACA 0008-1.1-25
NACA 0005-.825-50
Thanks
Mike

RE: NACA airfoil
The general 4-digit NACA airfoil is defined as follows:
First digit = Maximum camber as a percent of chord length
Second digit = Position along chord where maximum camber occurs
Third and Fourth digits = Maximum thickness, in percent of chord length.
For example, a NACA 2412 has a maximum camber of 2% of the chord length. The maximum camber occurs at a position .4 chord from the leading edge, and the maximum thickness is 12%.
The two leading zeros would be indicative of a symmetric airfoil.
