Acoustic Emissions Verification Testing of International Space Station Experiment Racks at the NASA Glenn Research Center Acoustical Testing Laboratory

摘要

The Acoustical Testing Laboratory (ATL) at the National Aeronautics and Space Administration(NASA) John H. Glenn Research Center (GRC) in Cleveland, Ohio, provides acoustic emissiontesting and noise control engineering services for a variety of customers, particularly developersof equipment and science experiments manifested for NASA’s manned space missions. TheATL provides a comprehensive array of acoustical testing services, including sound pressurelevel testing per ISO 112011 and sound power level testing per ISO 37442. The ATL isaccredited by the National Voluntary Laboratory Accreditation Program (NVLAP code 200557-0) for both of these standards.During the past five years the ATL has tested a variety of space payloads for theInternational Space Station (ISS), with its primary customer being the Fluids and CombustionFacility (FCF), a two-rack microgravity research facility being developed at GRC for the USALaboratory Module of the ISS 3,4,5. FCF will accommodate the unique challenges associated withinvestigating the behavior of fluids and combustion processes in microgravity and will provideservices and capabilities comparable to those found in traditional Earth-based laboratories. TheFluids Integrated Rack (FIR) will house a succession of fluid physics experiments, and theCombustion Integrated Rack (CIR) will support combustion experiments.
