Regarding the laying out of the data points of a NACA Aerofoil..
Given: The data points are referenced to a percentage of the chord (“x” axis) line….
Question, are the ordinates (+/-)of the “y” direction, given perpendicular to the chord line, or are
they given as a perpendicular direction to the local slope of the mean line, from the
mean line at that Percentage of the chord line ??
Question, when scaling the Chord Line, are the (+/-) “y” data points scaled with the
same scale factor as the chord line, or must a complex function be used to generate those
data points ??
