14 -- 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 1400- - - . 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 (801)777-7623.
