Testing was conducted on the NASA Space Shuttle Orbiter, Endeavour, to determine the high frequency shielding capability of three major cavities; the flight deck, the mid-deck/crew quarters and the payload bay. Testing was performed using highly modified reverberation techniques.
The Intercommunications System (ICs) on a Navy aircraft was evaluated for numerous electromagnetic interference (EMI) problems that had been reported during use in the Fleet. EM1 had caused the system to exhibit: randomly flashing lights, shut down and resetting of certain components, locked keying, and audio distortion. The problems were so severe that interference would make the system completely unusable, and seriously compromise the mission. Since it was not feasible to obtain all of the components and cabling of the system for testing in the EM1 lab, conducted susceptibility testing was initially performed in an aircraft integration laboratory. Susceptibilities were found, fixes were attempted, and retesting was performed. For a more complete evaluation, radiated susceptibility testing is planned on the aircraft using reverberation chamber techniques. This paper discusses the testing techniques usedto be used, susceptibilities found, and the fixes performed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
