Supersonic membrane decelerators, like parachutes or inflatable aero-shells, are presently used for planetary re-entry in robotic missions. It is known from flight tests and experiments that such membrane decelerators are susceptible to aeroelastic instabilities in certain flight regimes. To study this, we developed a numerical solution strategy by combining several novel developments in membranes, fluid-membrane interaction, fluid dynamics and block-structured adaptive mesh refinement. In this presentation, I will introduce the developed overall computational framework and discuss, in particular, the challenges in modelling the structural components of the membrane decelerators.
