Localization, Characterization, and Modeling of Freestream Disturbances in Hypersonic Wind Tunnels

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. Performers must implement novel non-intrusive or minimally intrusive diagnostics and coupled with multi-fidelity simulation strategies to accurately trace the evolution of unwanted thermo-fluid-dynamic disturbances from their point of origin to the test section.

The full objective, description, Phase I, II and III requirements and evaluation criteria are in the official topic on DSIP.
