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.

Join Dr. Rodney Bowersox as he presents an overview of the OUSD Joint Hypersonics Transition Office sponsored University Consortium for Applied Hypersonics (UCAH). UCAH is envisioned as a collaborative inclusive network of universities, government, industry, and national laboratories collaborating to deliver time-sensitive applied hypersonic research and prototype solutions to the DOD. The consortium membership includes 80 universities, 76 industries, and 8 national labs, FFRDCs and UARCs. A description of the organization structure and engagement opportunities is provided.

Additionally, Bowersox will present an overview of the hypersonic turbulent aerothermochemistry research at Texas A&M University. The focus of the research is to extend modeling to include mechanical, thermal, and chemical non-equilibrium effects. Three examples are discussed: (1) 2-D Mach 5 flow with pressure gradients, (2) 2-D Mach 6 flow with thermal non-equilibrium plasma, and (3) the BOLT II Flight Test in Memory of Mike Holden, which will produce a 3-D Mach 6 boundary layer with pressure gradients, non-iso-thermal walls, and a complex transition process.
