  6. Precision Of FLEET Velocimetry Using High-Speed CMOS Camera Systems
    6/15/2017

    Femtosecond laser electronic excitation tagging (FLEET) is an optical measurement technique that permits quantitative velocimetry of unseeded air or nitrogen using a single laser and a single camera. This paper seeks to determine the fundamental precision of the FLEET technique using high-speed complementary metal-oxide semiconductor (CMOS) cameras. 

  7. Development Of Background-Oriented Schlieren For NASA Langley Research Center Ground Test Facilities
    6/13/2017

    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.
