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.
