The primary mission of the Boundary-Layer Stability and Transition Laboratory (BLST) is to advance the science of boundary-layer stability and transition and related phenomena such as aerodynamic heating. BLST is an experimental aerodynamics facility with a nationally unique pair of high-speed (Mach 4 and Mach 5) wind tunnels, which enable faculty, staff, and students at all levels to engage in basic and applied research on topics relevant to a pressing national need.
