86770 - Numerical Study of a Cross Parachute Using Fluid-Structure Interaction Method 

The fluid-structure interation(FSI) numerical simulation of  a cross parachure is carried out. The simulation model solves the N-S equation by the ALE method, the FSI is based on the penalty function method, and The deformation of parachute is calculated by finite element method(FEM). The parachute fabric permeability is considered using Darcy's law. The simulation results include parachute opening load, drag coefficient, parachute stress, etc. The simulation results are compared with the wind tunnel test results and  the agreement is well. By comparing the results of different inflow velocities, the Influence of dynamic pressure change on the parachute opening process are analyzed.
