Hydra, A New Hybrid Thermal Protection System For Leo & Moon Mission Re-Entry Vehicles

The European Union FP7 project HYDRA addresses the development of a hybrid thermal protection solution, where a low density ablator is attached on top of a thermo-structural ceramic core by means of the use of high temperature adhesives. The project aims to design, integrate and verify a robust and lightweight thermal shield solution for atmospheric earth re-entry. The main advantage of a hybrid heat-shield is based on the capability of the thin ablative top layer to bear high thermal loads, while the tough ceramic composite underneath provides structural support.
