At the forefront of hypersonics research, or at least quite close to it

The High-Speed Aerodynamics and Propulsion Laboratory (HAPL) at the University of Maryland, led by Associate Professor Stuart Laurence, specializes in investigations of a wide variety of high-speed flow problems, including hypersonic boundary-layer transition, aerodynamic interactions between free-flying bodies, shock-wave/boundary-layer interactions, fluid-structure interactions, scramjet unstart, and diagnostic development.


HAPL aims to make significant contributions to our fundamental understanding of high-speed flow problems, whilst providing students with access to world-class experimental facilities for research and education.
