What is it about?
In this study an ultra-high-repetition-rate laser/camera setup was used to look at how nitric oxide is formed under hypersonic Mach stem conditions and subsequently spatially compared our findings with the industry-standard simulation method. The comparison showed areas where the data compared extremely well to the simulation and several areas where some differences were observed.

Why is it important?
Hypersonic flight is currently gaining more and more interest from the general engineering and scientific community. Several reasons for that are as it provides an access to space and new transportation capabilities. In order to ultimately be able to control the environment under the extreme conditions of hypersonic flight, we need to first understand it. Additionally, the Mach Reflection flow field was of great interest as it provides a unique opportunity to study strong thermochemical nonequilibrium conditions.
