6/18/2008 - EGLIN AIR FORCE BASE, FL -- The A-10C
Thunderbolt II is undergoing state-of-the-art 3-D
measurement to help the close-air support fighter jet
carry the latest in smart weapons technology June 9-20
at the King Hangar here.
The 46th Test Wing's Air Force SEEK EAGLE Office
(AFSEO) Computerized Physical Fit team is collecting
approximately 100,000 3-dimensional data points on an
A-10C aircraft. The A-10C being measured is on loan
from the Maryland National Guard and is being used for
the test under direction of the test wing's 40th
Flight Test Squadron. The team is using their V-STARS,
or Visibility Size and Shape Targeting Accuracy Room
Scale, photogrammetry system of triangulation to
collect data. Data points are being collected on every
external surface of the aircraft. These data points
will be used to build a digital model of the aircraft
that is representative of operational aircraft. Once
complete, dimensions of the model will be accurate
within 0.03 inches of the aircraft measured.
"In the 1970s, when the A-10 was produced,
engineering analyses were done with 2-D drawing and
extensive ground and flight testing. Today, 3-D models
are created as aircraft are being designed," said Mark
Hillman, Air Force SEEK EAGLE Office, Lead Engineer,
Fit/Function. "These 3-D models are used as the basis
for many of AFSEO's engineering analyses including:
computerized physical fit, computational fluid
dynamics, electromagnetic interference/compatibility
and store separations. This new modeling capability
will help minimize store integration costs by reducing
the number of ground and flight tests."
"Over the years, the A-10 has proven itself as a
true asset to the warfighter and has undergone several
upgrades to include completely refitting many of the
planes in our inventory with new parts," said Paul
Collins, 46 SK, Computerized Physical Fit Team Lead.
"This is just one more step in integrating an old but
viable, combat-proven machine with the most current
The V-STARS program is helping bring an aging
aircraft online with the latest technological
advances, making it a stronger asset to the United
States and a deterrent to the enemy.
"We did this with other aircraft in the Air Force
arsenal," Mr. Collins said. "This is just the latest
aircraft targeted to undergo the V-STARS measurement.
Our end product is to create a digitized model to help
us upgrade the aircraft similar to what we did with
the B-52H Stratofortress. Many of our aircraft are
still very useful work horses and all they need is to
be brought online with new technology to continue to
be a huge asset."
