Modern Developments in the Design of Hypersonic Inlets
Hypersonic inlet designs have developed through a range of geometric configurations, from axi-symmertric, to two-dimensional to fully three-dimensional. The key to modern designs is to take advantage of the benefits of three dimensionality in ways that satisfy broader constraints such as capability, efficiency and startability. This talk will discuss current ideas in this area.

Arc-jet Overview, Modeling, and Uncertainty for Hypersonic Material Environmental Test and Evaluation
Arc-jet test facilities are crucial for testing high-temperature material systems while simulating heating and flow environments experienced in atmospheric entry and hypersonic flight. This presentation will briefly provide background on simulation parameters and the unique capability of arc-jet facilities. The primary portion of the presentation will provide a general overview of an arc jet, including components, how it works, instrumentation, and types of testing. Technical challenges and considerations will also be discussed related to arc-jet modelling and uncertainties.

Theories and Technologies of Detonation-driven Hypervelocity Shock Tunnels
High-enthalpy hypersonic tunnel is one of the critical technologies for hypersonics. The development of the JF-22 Hypervelocity Shock Tunnel will be reported, including the concept of the forward detonation cavity driver, the design principals of hypervelocity shock tunnels, key technologies and calibration results of the JF-22 Hypervelocity Shock Tunnel.

Optical Diagnostics in Supersonic Combustion Environments
Quantitative measurement in supersonic combustion environments is challenging due to the limited measurement time duration in the fast-volving compressible reacting flow. To monitor and understand the flow behaviors in supersonic combustors, high-sampling rate sensors and short-exposure optical measurements are essential. Spontaneous photon emission from excited species and laser-enforced fluorescence/scattering signals can provide quantitative property information such as density, temperature, composition, and local velocity when properly processed. Some possible combinations of recently developed optical measurement methods will be presented.
Dr. Gerald Hagemann
Industry / Agency Cooperation to Face Challenges in Research
The presentation addresses research challenges for aerospace applications, and how through cooperation between industry and research partners these challenges are addressed. The discussion includes aerothermal challenges, but also material technology towards generative methods with applications where industrial standards in terms of machines are not (yet) available.
Application towards fullscale hardware and flight will be given.

Impact of surface roughness on hypersonic boundary-layer transition: from asymptotics to numerics
Surface roughness would influence hypersonic boundary-layer transition through the local receptivity and local scattering mechanisms, which are formulated by the high-Reynolds-number asymptotic analysis. The asymptotic theory is confirmed to be accurate by numerics, which leads to a transition-prediction model for hypersonic boundary layers with surface imperfections.
