Inflatable re-entry vehicle is a one of the candidates for future re-entry systems. This can afford some advantages in the entry, descent, and landing (EDL) approach. By using numerical simulation, we can observe flow field around vehicle and obtain aerodynamic characteristics. However, because inflatable re-entry vehicle is generally deformed by aerodynamic force, introduction of deformation model is required for more accurate evaluation of aerodynamics. In this research, we simulated membrane deformation by using particle method coupled with flow field simulation. As simulation codes for flow field, FrontFlow/Red and FaSTAR which have been respectively developed by Hokkaido University and JAXA are used.
