6-Series Camber Line

The equations for the 6-series camber lines are rather complicated and there is little value in displaying them here.

They may be found

1. on p.8 of NASA TM 4741
2. as Eq. 4.26 and 4.27 on p.74 of Abbott and von Doenhoff, Theory of Wing Sections
3. as Eq. 6 on p.264 of NACA Rep. 824

6-series camber lines are specified with a parameter a, where a is a fraction of chord. The intent is to provide a uniform loading from the leading edge to the station x=a and a loading that decreases linearly to zero thereafter.
