    Abstract

    National Aeronautics and Space Administration (NASA) Johnson Space Center White Sands Test Facility (WSTF) performed particle impact testing to determine whether there is a particle impact ignition hazard in the quick disconnects (QDs) in the environmental control and life support system (ECLSS) on the International Space Station (ISS). Testing included standard supersonic and subsonic particle impact tests on 15–5 PH stainless steel, as well as tests performed on a QD simulator. This paper summarizes the particle impact tests completed at WSTF. Although there was an ignition in test series 4, it was determined that the ignition was caused by the presence of a machining imperfection. The sum of all the test results and analysis enabled NASA to conclude that the risk of particle impact ignition hazard in the ISS ECLSS QDs was acceptable.
