Development Of Background-Oriented Schlieren For NASA Langley Research Center Ground Test Facilities

By Brett F. Bathel (NASA Langley Research Center), et al.

This paper provides an overview of recent wind tunnel tests performed at the NASA Langley Research Center where the Background-Oriented Schlieren (BOS) technique was used to provide information pertaining to flow-field density disturbances. The facilities where the BOS technique was applied included the National Transonic Facility (NTF), Transonic Dynamics Tunnel (TDT), 31-Inch mach 10 air tunnel, 15-Inch mach 6 high-temperature air tunnel, rotor test cell at the 14×22 subsonic tunnel, and a 13-Inch low-speed tunnel.
