IFDIS Test Program Set (TPS) Development

The objective of this effort is the design and manufacture of prototype Test Program Sets (TPSs) for Air Force and NAVAIR Intermittent Fault Detection and Isolation System (IFDIS) test stations. Intermittent failures are a growing problem in aging DoD weapon system electronic equipment. The Intermittent Fault Detection and Isolation System (IFDIS) is an electronic test system developed under the SBIR program to detect and isolate operational environment induced intermittent failures in aerospace avionics backplane and chassis conductive paths. IFDIS consists of an Intermittent Fault Detector (IFD), an environmental chamber, a shaker and system control software. An IFDIS Interface Test Adapter (ITA) is unique to an LRU/WRA and connects to the specific LRU/WRA chassis. The LRU/WRA is then placed in the environmental chamber to be tested with the IFDIS. This Phase II follow-on SBIR will adapt and advance the IFDIS technology to new military avionics assets that have been identified by the Air Force and Navy as having high CND/RTOK/No Fault Found rates.
