N2 - A high fidelity multiphase computational framework is presented for the simulation of parachute inflation in supersonic turbulent flows. Unlike previous investigations in this area, the framework considers the effect of the initial folded state of the parachute, flow compressibility in the porous fabric material, and the interactions between the fluid and the suspension lines. This framework is applied to a set of quasi-2D preliminary parachute inflation simulations. The results show (a) the loss of drag performance in supersonic regimes is due to the shock suspension line interactions, and (b) the maximum stress in the parachute canopy differs significantly when starting from an initial folded configuration and a flat (post-inflated) configuration.
