GA(W)-1 2

[Nagler]

Has GA(W)-1 2D data been published and is it available.
I am looking Cl, Cd and Cm vs alpha at 0, 10, 20 and 40 degrees Fowler flap angle all at RE's 2, 4, 6 and 8x10*6 and std roughness. Many thanks.

I see there are several references to

http://naca.larc.nasa.gov.

Yesterday I went through the listing of reports, about 1/3 of them to get their titles. I did not find this one.

By all means get a copy of the SAE report 740365.

"A Fowler Flap System for a High-Performance
General Aviation Airfoil"

by Dr. Bill Wentz et al Wichita State U.

It is based on the GA(W)1 and really gets into
the relationship between the wing trailing edge
and flap leading edge.
