What is it about?
Aerodynamic heating is a dominant factor affecting hypersonic flights in the sensible atmosphere. We have measured the thermal loads on a scramjet engine operating in a harsh hypersonic environment, which was duplicated in our laboratory. We have utilized wall-mounted coaxial thermocouple sensors to measure thermal quantities non-intrusively.

Why is it important?
In practice, understanding the severe aerodynamic heating of a scramjet engine during atmospheric flight at hypervelocities is very important for its design as well as for the implementation of thermal management strategies, as they directly impact the performance, efficiency, and integrity of the scramjet engine.
Perspectives
Writing this paper was very exciting as it has co-authors with whom I have had long fruitful collaborations. This paper also lead to some engineering implications as the need for cooling methods and the requirement for new materials aside from the definition of the best location and installation of thermal sensors on hypersonic systems.
