Vultee Airfoil Usage
On designations: many of the airfoils listed here have "mod"
at the end of their designation. Typically, this means that either the camber
line has been modified, the leading edge contour has been modified or that
the trailing edge thickness has been changed.

Tests of NACA 0009, 0012, and 0018 airfoils in the full-scale
tunnel
Goett, Harry J Bullivant, W Kenneth
NACA Report 647
1939
An investigation was conducted in the NACA full-scale wind tunnel
to determine the aerodynamic characteristics of the NACA 0009, 0012, and
0018 airfoils, with the ultimate purpose of providing data to be used as
a basis for comparison with other wind-tunnel data, mainly in the study
of scale and turbulence effects. Three symmetrical 6 by 36-foot rectangular
airfoils were used. The Reynolds number range for minimum drag was form
1,800,000 to 7,000,000 and for maximum lift, from 1,700,000 to 4,500,000.
The effect of rounded tips was determined for each of the airfoils. Tests
were also made of the NACA 0012 airfoil equipped with a 0.20c full-span
split flap hinged at 0.80c. Tuft surveys were included to show the progressive
breakdown of flow near maximum lift. Momentum surveys were made in conjunction
with force measurements at zero lift as an aid in converting force-test
data to section coefficients.
