Constellation Program (CxP) Crew Exploration Vehicle (CEV) Parachute Assembly System (CPAS) Independent Design Reliability Assessment: Appendices

This report documents the activities, findings, and NASA Engineering and Safety Center (NESC) recommendations of a multidiscipline team to independently assess the Constellation Program (CxP) Crew Exploration Vehicle (CEV) Parachute Assembly System (CPAS). This assessment occurred during a period of 15 noncontiguous months between December 2008 and April 2010, prior to the CPAS Project’s Preliminary Design Review (PDR) in August 2010. The assessment team‘s planned objectives were to identify reliability-enhancing opportunities for the CPAS Project: Parachute system design, Reliability estimation methodologies, Development program (development tests and analysis, and verification plans), Design development and integration practices.
