Localization, Characterization, and Modeling of Freestream Disturbances in Hypersonic Wind Tunnels
AI Overview
This STTR seeks novel diagnostic systems and computational models to characterize freestream noise sources in hypersonic wind tunnels, particularly in regions inaccessible to conventional optical techniques. Deliverables will enable better understanding of noise generation upstream and improve ground-test facility performance for high-speed vehicle evaluation.

Key Details
Official Description
Hypersonic ground-test facilities are critical for evaluating aerodynamic forces, aerothermodynamic heating, and boundary-layer transition (BLT) behavior on high-speed flight vehicles. However, conventional hypersonic wind tunnels are plagued by high-intensity freestream noise present in the test section. Because these disturbances build, focus, and propagate downstream, the fundamental understanding of their evolution may require a potentially deep analysis within the upstream components of the...
