Disk-Gap-Band パラシュートのための超音速領域における流体構造連成解析

抄録

The Mars landing system has been developed with a disk-gap-band (DGB) parachute in supersonic flow regime. The Mars' thin density creates a scaling challenge that is hard to overcome in windtunnel tests. Therefore, a computational analysis will require for parachute design. We use NURBS basis functions for spatial discretization in both structural and fluid mechanics computations. The parachute shape becomes smoother than what we get from a typical finite element discretization.
