Space Chambers Contamination Diagnostics and Analysis
Abstract
In order for the AEDC to meet its requirement to be the Center for Expertise (COE) for space environmental simulation, a technology effort was structured to provide the required enabling technologies. The proper simulation of the space environment in a ground test chamber requires a complete characterization and control of facility, chamber, and test article generated contaminants. To meet these testing requirements, the objectives of this project included the development of (1) laboratory diagnostics support, (2) online diagnostic instrumentation, and (3) computational analysis capability. A laboratory capability was developed to screen materials for contamination potential and to identify unknown contaminants. New diagnostic techniques for more sensitive contaminant mass measurements and particulate cleanliness level measurements were identified. Contamination analysis development included evaluation of codes to simulate molecular flow in test chambers, establishment of a material property database, and installation of library data and algorithms for identification of unknown contaminants by mass spectra searches.
