Summary: On this episode of the Illinois Innovators Podcast, we explore hypersonics. When a vehicle travels faster than the speed of sound, its exterior surface becomes extremely hot — risking the safety of the people and cargo inside. Molecules in the flow around the vehicle collide and change, creating a shockwave. This hypersonic environment is difficult to understand and even more difficult to study. We asked Marco Panesi to clarify some of the mysteries of hypersonics and tell us what he and his colleagues are working on to better understand the phenomenon. He is a professor in the Department of Aerospace Engineering, a Caterpillar Faculty Scholar, and director of the Center for Hypersonics and Entry Systems Studies.
