A fast procedure to simulate the unsteady aerodynamic characteristics of a parachute cluster in the vicinity of a capsule is presented. This problem is modeled using a well-validated flow solver, which solves the Reynolds-averaged Navier–Stokes equations for steady and unsteady compressible/incompressible flows around general geometries using an overset grid approach. Results are validated using comparisons with classical theory and experiments. The fast generation of a large aerodynamic database is accomplished using the dual-level parallel protocol on a massively parallel supercomputer. Results are demonstrated by generating aerodynamic response surfaces for steady and unsteady cases.
