Abstract

This paper describes two mathematical purge models, transient and steady-state, developed for investigation of purging critical space systems with stringent humidity requirements. The developed single-cell purge model correlates well with measured data from a purge-test engineering model. The validated purge models are being used to support various purging activities/plans associated with spacecraft/payload integration and test and spacecraft/launch vehicle integration. This paper also includes a dew-point analysis to address water-vapor condensation concern for purging critical space systems.
