NACA Airfoil significance ( 4-digit system )
 NACA xxxx
1. First digit designates the maximum value of camber (5) as percentage of chord
2. Second digit designates the maximum value camber at
0,1 from the airfoil leading edge.
3. Last two digits designates 
the maximum thickness of the airfoil
as percent of the chord.
