Abstract

Parachutes are increasingly used to land space structures on Earth and other planets (e.g., Mars). Supersonic parachute deployment is a challenging fluid structure interaction (FSI) problem, and its physics-based computational simulation is a daunting task. A research collaboration between the Farhat Research Group (FRG) at Stanford University and the Jet Propulsion Laboratory (JPL) at the California Institute of Technology (Caltech) intends to assess the viability of a sophisticated suite of multi-physics codes, namely, the AERO Suite developed by FRG, and to enhance it further so that it can be exploited for simulating supersonic parachute deployment. This Suite features unique capabilities for the simulation of highly nonlinear FSI problems that have been verified and validated for related nonlinear aeroelasticity problems, and for underwater explosion and implosion problems. As part of the effort, a suite of purely structural mechanics and structural dynamics test problems (VERTS) relevant to parachute behavior has been developed for verifying AERO-S, the structural analyzer component of this software Suite. This paper summarizes the findings from the application of this verification test suite to AERO-S. Specifically, the study correlates the AERO-S VERTS results with analytical solutions (when available), results from other finite-element codes, and results reported in the literature. The reported VERTS results intend to highlight the existing capabilities of AERO-S and identify potential technology gaps to be incorporated into AERO-S during this collaborative effort.
