Localization, Characterization, and Modeling of Freestream Disturbances in Hypersonic Wind Tunnels
Summary
The DARPA STTR topic seeks proposals to develop and demonstrate methods for localizing, characterizing, and modeling upstream noise and flow disturbances in hypersonic wind tunnels, including novel non‑intrusive diagnostics for hard‑to‑access regions. The effort aims to improve understanding of freestream disturbances that affect aerodynamic testing by coupling advanced sensing with multi‑fidelity simulations.
