We present a parallel computational strategy for carrying out 3-D simulations of parachute fluid-structure interaction (FSI), and demonstrate the strategy for simulations of airdrop performance and control phenomena in terminal descent. The strategy uses a stabilized spacetime formulation of the time-dependent, 3-D NavierStokes equations of incompressible flows for the fluid dynamics (FD) solution. Turbulent features of the flow are accounted for using a zero-equation turbulence model. A finite element formulation derived from the principle of virtual work is used for the parachute structural dynamics (SD). Coupling of the FD with the SD is implemented over the the fluid-structure interface, which is the parachute canopy surface. Large deformations of the structure are handled in the FD mesh using an automatic mesh moving scheme.
