A comparison of bulk cable injection to reverberation chamber methods on a fault tolerant flight control computer

摘要

The Systems and Airframe Failure Emulation Testing and Integration (SAFETI) Laboratory at the NASA Langley Research Center (LaRC) has been established to study radiated field effects on complex avionics systems and control system components. Established in the first quarter of 2000, it works hand in hand with the High Intensity Radiated Fields (HIRF) laboratory by using the mode stirred chambers that were constructed and certified during 1995-96. This paper describes the conducted tests, the data collected, and conclusions derived from comparing the reverberation chamber environment to bulk cable injection technique using a quadredundant flight control computer as a test article. This information will be used to determine if bulk cable injection techniques can be used as a possible alternative to reverberation chambers in pre-testing for radiation fields susceptibility.
