Hypersonics offers many advantages for aerospace applications in civil transport, space access, vehicle reusability, or strategic defense. However, a hypersonic regime is extremely demanding for vehicle design and those solutions need to be developed over the severe flight conditions it imposes. Aerothermodynamic phenomena at hypervelocity need to be better understood as they have a significant impact on the hypersonic vehicle design. This is especially true for their optimization, which is hardly addressed since such development is conducted with a conservative, or, more frequently, overconservative approach. While a number of active research programs are still dedicated to those investigations, this prevents us from benefiting from the full potential of hypersonic flight.

To reveal these challenges the presentation will give an overview of hypersonic flows and how they affect aerospace missions. The articulation of testing methodologies in high enthalpy and plasma facilities with high fidelity CFD tools for the study of critical aerothermodynamic phenomena in very high-speed flows will be discussed. Finally, the development from ground testing research to real-flight situation for the design of hypersonic systems and aerospace applications will be presented.

Speaker:
Prof. Olivier Chazot
Head of Aeronautics & Aerospace
von Karman Institute for Fluid Dynamics

Olivier Chazot is professor and head of the Aeronautics and Aerospace Department at the Von Karman Institute for Fluid Dynamics (VKI). He is an expert in hypersonic aerothermodynamics. His research activities cover ground testing strategy in high enthalpy facilities and plasma wind tunnels for aerospace re-entry missions, modeling development, and CFD validation. He specifically studies laminar to turbulent transition in hypersonic regime and gas-surface interactions on TPS in reacting flows. His main research focus is the duplication of real-flight conditions in ground testing facilities. He participated in multiple ESA missions for the development of flight experiments like the Mars Express mission, EXPERT probe, IXV and Space Rider programs, and QARMAN re-entry CubeSat.
