Abstract

This paper reports a model verification and validation assessment to support the development and application of a new supersonic parachute inflation simulation capability. The new capability is under development by the Farhat Research Group at Stanford University in a collaboration with the NASA Jet Propulsion Laboratory. The objective of the new simulation capability is to enable the physics based modeling of the inflation of a parachute decelerator in supersonic flow during entry into the Martian atmosphere. The reported model verification and validation assessment was undertaken to identify key gaps in the modeling capability of the software, to select verification tests of the software, and to anticipate validation tests for the modeled phenomena. A phenomena identification and ranking table (PIRT) of the simulation was developed to support this gap analysis. The results of this assessment have been incorporated into the software development plan, and into model verification and validation test suites reported in companion papers. This paper presents the development of the PIRT and discusses the results of the assessment.
