From the topic

Develop and demonstrate a robust methodology to localize, characterize and model upstream noise and flow disturbances in hypersonic wind tunnels, specifically targeting high-risk, hard-to-access regions upstream of the test section (e.g., driver, reservoir, nozzle throat and walls) where traditional optical access is restricted or unavailable.
