COMMERCE BUSINESS DAILY ISSUE OF SEPTEMBER 20,1996 PSA#1684Department Of The Air Force, Ogden Air Logistics Center, Hill Air Force
Base, Ut 84056-5825 16 -- CT AND NDI FACILITIES POC For copy, Debbie
Mcgowan/Tich/(801)777-2719, For additional information contact Debbie
Mcgowan/Tich/(801)777-2719 Item 0001 NSN 1600- - - . Item 0002 The
Ogden Air Logistics Center, Hill AFB UT, has state of the art Computed
Tomography (CT) and Nondestructive Inspection (NDI) facilities. These
facilities have been typically used to perform a wide variety of
inspection services for the Department of Defense. However, DOD
contractors and universities have purchased scanning services through
the use of Memorandum of Agreements (MOA) and Cooperative Research and
Development Agreements (CRDA). Capabilities include, but are not
limited to: The CT facilities house two of the most powerful and
versatile systems in the world. The smaller of the two is an ICT-1500.
System specifications and inspection envelope are as follows: 58 inch
diameter turntable, 100 inches high, and a maximum table weight of 5
tons. The radiation source is a Varian Linatron 3000, operating at 6,
9, or 11 million electron volts (MEV), with a 2.0 mm focal spot. The
x-ray beam is collimated to a 30 degree fan angle horizontally and a
two degree angle vertically. Resolution capability is three line-pairs
per millimeter. Our second system is an ICT-2500. System
specifications and inspection envelope are as follows: 96 inch diameter
turntable, 348 inches high, and a maximum table weight of 60 tons.
Resolution capability is a minimum of three line-pairs per centimeter
and operates at either 9 or 15 MEV with a 1.5 mm focal spot. Radiation
output is 16,000 rads per minute at one meter. The x-ray beam is
collimated to a 20 degree fan angle horizontally and 1.5 degrees
vertically. CT image data can be interfaced with a computer aided
design (CAD) software system to provide accurate contours and surface
meshes in minutes utilizing four types of main viewers: Analyzing CT
slices, visualizing volumetric CT images, displaying contours, and
displaying meshes. The AUSS-V (Automated Ultrasonic Scanning System,
fifth generation) performs computer-controlled, contour-following
ultrasonic inspection of adhesively bonded, metal, or composite
assemblies having complex, contoured shapes. The system performs
through-transmission or pulse-echo test using water squirters for
ultrasonic signal coupling between the scanner and the part. The AUSS-V
is capable of scanning up to 30 inches per second. Maximum working
envelope is 234 inches long, and 98 inches high. The system used
ultrasonic frequencies in the 0.4-15 megahertz (MHz) range to inspect
for delaminations, porosity, disbonds voids, ply slippage, and foreign
materials. Using advanced control hardware and software, the AUSS-V is
able to scan parts having compound curvature. Once a part has been
programmed into the system, another similar part need only be located
using three reference points and the part can then be automatically
scanned. This request for interest is designed to provide test and
evaluation services to the public that are not reasonable available in
private industry. Expressions of interest and questions should be
forwarded to Fred Doutre or Debbie McGowan, OO-ALC/TICH, 5851 F. Ave
(Bldg 849), 84056- 5713, Telephone (801)777-2719 or 777-4071. Fax
