Inflatable aeroshell

Aerodynamics and aerodynamic heating of inflatable aeroshell
The inflatable reentry vehicle is an innovative technology that uses a light and flexible membrane aeroshell. However, the aeroshell can be deformed significantly by aerodynamic forces. In this case, complicated fluid-structure interaction arises. It is important to accurately predict the aerodynamic heating environment and aerodynamic forces during atmospheric reentry. We develop a new coupled analysis model and addressing the coupled problems of an inflatable reentry vehicle.
