  • This image presents a visualization of the surface heat transfer on the full-scale Boundary Layer Transition, or BOLT, experiment model in the CUBRC LENS II shock tunnel in Buffalo, New York. Areas of higher heating, which are seen in orange and red, are due to boundary-layer transition. The aim of the BOLT experiment, which is being sponsored by the Air Force Research Laboratory/Air Force Office of Scientific Research and conducted by the Johns Hopkins University Applied Physics Laboratory (JHU-APL), along with the University of Minnesota, Purdue University, Texas A&M University, AFRL Aerospace Systems Directorate, NASA Langley, CUBRC, VirtusAero and DLR in Germany, is to predict the state of the boundary layer, or the thin layer of air near the surface, of the new canonical shape shown in the photo. Personnel at AEDC Hypervelocity Wind Tunnel 9 in White Oak, Maryland, provided training to JHU-APL staff members on how to install instrumentation used to measure temperatures on the BOLT hardware.

    Tunnel 9 personnel provides guidance for hypersonic experiment

    When those conducting Air Force-sponsored basic science research in hypersonic aerodynamics needed some advice, they relied upon the expertise of engineers and technicians at AEDC Hypervelocity Wind Tunnel 9 in White Oak, Maryland.Earlier this year, personnel from Tunnel 9 provided instrumentation installation training to members of the research

    Hypervelocity capabilities advance to new highs at AEDC Tunnel 9

    AEDC Hypervelocity Wind Tunnel 9 in White Oak, Maryland, is on the verge of delivering an unprecedented capability. In late April, the team at Tunnel 9 completed an initial shakeout of the Mach 18 system and, later this year, facility engineers are set to begin a full calibration on Mach 18. If successful, this would allow for testing at Mach
