An Overview of Follow-On Testing Activities of the A-3 Subscale Diffuser Test Project

An overview of NASA Stennis Space Center's (SSC) A-3 Subscale Diffuser Test (SDT) Project is presented. The original scope of the SDT Project, conducted from April 2007 to January 2008, collected data to support mitigation of risk associated with design and procurement activities of the A-3 Test Stand Project, an effort to construct a simulated altitude test facility at SSC in support of NASA's Constellation Program. Follow-on tests were conducted from May 2008 through August 2009, utilizing the SDT test setup as a testbed for additional risk mitigation activities. Included are descriptions of the Subscale Diffuser (SD) test article, the test facility configuration, and test approaches.

An Overview of the A-3 Subscale Diffuser Test Project

The Subscale Diffuser Test (SDT) Project comprised a series of tests of a subscale model of SSC s A-3 Test Stand diffuser. SDT was conducted at NASA s Stennis Space Center (SSC) Apr 2007 - Jan 2008. Purpose of SDT was to mitigate design risk for the A-3 diffuser. Initial scope of the SDT project successfully completed in Jan 2008. Follow-on A-3 risk mitigation testing being planned/considered. This presentation presents an overview of the SDT project.
