International Space Station Environmental Control and Life Support System - Verification and Test Program for the United States Airlock Element 2000-01-2295

The United States Airlock provides the capability to sustain life in the habitable environment of the International Space Station (ISS) and also supports the Extravehicular Activities (EVA) by providing a means for the crew to translate from the pressurized station environment to space vacuum. The Airlock consists of the Crewlock and Equipment Lock pressurized volumes, two high-pressure oxygen and two high-pressure nitrogen gas tanks. The Airlock Environmental Control and Life Support (ECLS) System consists of the following subsystems: Atmosphere Control and Supply (ACS), Atmosphere Revitalization (AR), Fire Detection and Suppression (FDS) and Temperature and Humidity Control (THC). This paper provides an overview of the Airlock ECLS System and details the verification and testing methodologies utilized during the Qualification test program.
