Hello--

I am looking for the following data for the Boeing 767 & 757 wings:

***NACA or NASA airfoil number, or a close approximation.
***Angle of incidince across the wing.

If anyone knows or can take a educated guess at this data, I would
certainly appreciate it!

Thanks

The all Boeing airliners since the 727 have airfoils custom designed by
Boeing engineers. The 707-100 airfoils are NACA 6X series sections on
modified NACA 230 and 60 series camber lines. By the time of the
707-300 these had been seriously butchered by the Yehuda, etc.

Boeing does not put their airfoil coordinates or test data in the
public domain. However, the wind tunnel test of a 737-200 is reported
in NASA TN D-5971, and the report contains airfoil coordinates.
Similarly, NASA CR-159093 contains the coordinates of an airfoil that is
either that on the outboard wing of the 767 or is closely related to
such.

I've often wondered about this. Couldn't a competitor obtain
coordinates for the wing, or the entire airplane, simply by
parking it on a flat surface and measuring it? This probably
doesn't answer the original question as Matt probably wouldn't
be able to get ahold of a 767 or 757, measure it, or even get
it into his garage.
