Testing Hypersonic Materials with Ultrabright X-Rays at Argonne
Scientists at Argonne National Laboratory, working with Embry-Riddle Aeronautical University, are using ultrabright X-rays to study materials under conditions similar to hypersonic flight. Their work takes advantage of the upgraded Advanced Photon Source (APS), which now produces X-ray beams up to 500 times brighter than before.
Key Takeaways
01
Flight Conditions
Argonne and Embry-Riddle are using APS’s ultrabright X-rays to mimic hypersonic flight conditions.
02
Energy Efficiency
The approach is more energy-efficient than traditional wind-tunnel testing.
03
Diagnostics
High-resolution diagnostics help capture fast, microscopic changes in material behavior.
04
Affordable
The results could guide development of affordable, durable materials for future hypersonic vehicles.
Simulating Hypersonic Flight, Less Energy
Rather than relying solely on high-enthalpy wind tunnels, the team uses high-resolution X-ray diagnostics to observe how materials evolve under extreme conditions. These X-rays make it possible to study microstructural changes in real time, while using fewer energy resources than traditional hypersonic testing methods.
Unprecedented Resolution & Speed
The upgraded X-ray beamlines at APS, paired with new fast, sensitive detectors, allow researchers to “map very thin samples” and track rapid chemical or crystallographic shifts. This enables detailed insight into how materials respond to high heat, stress, and other flight-relevant conditions.
Implications for Aircraft of the Future
By identifying materials that can survive the harsh environment of hypersonic flight, while being cost-effective and manufacturable, this research could unlock new opportunities for both military and commercial ultrafast aircraft, as well as cargo delivery systems.
