    A construction technique for wind tunnel models (1981)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: High strength, good surface finish, and corrosion resistance are imparted to miniature wind tunnel models by machining pressure channels as integral part of model. Pattern for pressure channels is scribed, machined, or photoetched before channels are drilled. Mating surfaces for channels are flashed and then diffusion brazed together.

    Detection of boundary-layer transitions in wind tunnels (1978)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: Accelerometer replaces stethoscope in technique for detection of laminar-to-turbulent boundary-layer transitions on wind-tunnel models. Technique allows measurements above or below atmospheric pressure because human operator is not required within tunnel. Data may be taken from accelerometer, and pressure transducer simultaneously, and delivered to systems for analysis.
