Non-Intrusive Diagnostics for Enhanced Hypersonic Flow Visualization and Characterization

Abstract

The Navy and the DoD at large demand a stronger knowledge of the flow environment experienced by aircraft and spacecraft traveling at high Mach numbers. Successful programs for both ballistic and reentry flightpaths demand designs which account for the challenges of highspeed flight, such as boundary-layer transition and shockwaves, and they require rigorous testing of vehicle prototypes in high-speed flow fields. Accurate prediction of vehicle performance requires diagnostics capable of making high-speed, spatially-resolved measurements of flow velocity. This project is motivated by the desire to have high-speed optical diagnostics developed in-house for testing and research purposes at NRL. Non-intrusive optical techniques have been considered a critical need for hypersonic testing because they can probe flow fields without creating physical disturbances that misrepresent flight conditions.
