Fluid-structure interaction simulations of the ASPIRE SR01 supersonic parachute flight test

High-fidelity fluid-structure interaction (FSI) simulations of the ASPIRE SR01 supersonic parachute flight test are performed through loose coupling computational fluid dynamics (CFD) and structural (CSD) solvers. The CFD solver employs a Cartesian adaptive mesh refinement (AMR) grid paradigm with ghost cell immersed boundary method to represent arbitrarily complex geometries, CSD uses MITC3 triangular shell Timoshenko beam elements discretize canopy suspension lines. resolution required capture deficit dynamic pressure in wake payload aerodynamic drag on is systematically studied via study before FSI conducted. presented consider inflation an initially folded freestream conditions matching line stretch event during test. total pull force at instance peak loading predicted within 10% data. sensitivity projected area domains another study, convergence respect domain demonstrated. vs time curve by each varies less than 1% indicating high degree repeatability low grid-related uncertainty. Remaining differences qualitative behavior quantitative difference thus determined stem from modeling errors such as lack deceleration, different initial flow states compared
