    Quantitative observation of light flash sensations experiment MA-106 (1976)
    In:  CASI
    Details
    Publication Date: 2006-01-12
    Description: Light flashes caused by the interaction of cosmic particles with the visual apparatus have been observed by astronauts on all space missions since Apollo 11. This Apollo Soyuz Test Project experiment compared measurements of the observer's visual sensitivity with measurements of the ambient radiation environment and with the frequency and character of the flashes observed. The data obtained reveal a latitude dependence of the frequency of observed flashes. This distribution of flashes is correlated with the distribution of cosmic particles with stopping power greater than 15 keV/ micrometers in the eye. The interaction of dark adaptation, specific ionization, and range of particles in the retina as factors in the visualization of particle passage is discussed.

    Interaction of aerodynamic noise with laminar boundary layers in supersonic wind tunnels (1984)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: The interaction between incoming aerodynamic noise and the supersonic laminar boundary layer is studied. The noise field is modeled as a Mach wave radiation field consisting of discrete waves emanating from coherent turbulent entities moving downstream within the supersonic turbulent boundary layer. The individual disturbances are likened to miniature sonic booms and the laminar boundary layer is staffed by the waves as the sources move downstream. The mean, autocorrelation, and power spectral density of the field are expressed in terms of the wave shapes and their average arrival rates. Some consideration is given to the possible appreciable thickness of the weak shock fronts. The emphasis in the interaction analysis is on the behavior of the shocklets in the noise field. The shocklets are shown to be focused by the laminar boundary layer in its outer region. Borrowing wave propagation terminology, this region is termed the caustic region. Using scaling laws from sonic boom work, focus factors at the caustic are estimated to vary from 2 to 6 for incoming shocklet strengths of 1 to .01 percent of the free stream pressure level. The situation regarding experimental evidence of the caustic region is reviewed.

    Analysis of an existing experiment on the interaction of acoustic waves with a laminar boundary layer (1982)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: The hot-wire anemometer amplitude data contained in the 1977 report of P. J. Shapiro entitled, ""The Influence of Sound Upon Laminar Boundary'' were reevaluated. Because the low-Reynolds number boundary layer disturbance data were misinterpreted, an effort was made to improve the corresponding disturbance growth rate curves. The data are modeled as the sum of upstream and downstream propagating acoustic waves and a wave representing the Tollmien-Schlichting (TS) wave. The amplitude and phase velocity of the latter wave were then adjusted so that the total signal reasonably matched the amplitude and phase angle hot-wire data along the plate laminar boundary layer. The revised rates show growth occurring further upstream than Shapiro found. It appears that the premature growth is due to the adverse pressure gradient created by the shape of the plate. Basic elements of sound propagation in ducts and the experimental and theoretical acoustic-stability literature are reviewed.

    Radiation measurements aboard Spacelab 1 (1984)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: The radiation environment inside Spacelab 1 was measured by a set of passive radiation detectors distributed throughout the volume inside the module, in the access tunnel, and outside on the pallet. Measurements of the low linear energy transfer (LET) component obtained from the thermoluminescence detectors ranged from 102 to 190 millirads, yielding an average low LET dose rate of 11.2 millirads/day inside the module, about twice the low LET dose rate measured on previous flights of the Space Shuttle. Because of the higher inclination of the orbit (57 versus 28.5 deg for previous Shuttle flights), substantial fluxes of highly ionizing high charge and energy galactic cosmic ray particles were observed, yielding an overall average mission dose-equivalent of about 150 millirems, more than three times higher than that measured on previous Shuttle missions.

    Light flash observations during Apollo-Soyuz (1976)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: A total of 82 visual events was reported by two dark-adapted astronauts during a 90-minute orbit at 225 km altitude. Silver chloride crystal events for that orbit totaled 69 stopping protons and alphas per sq cm and 304 heavy ions with stopping power of 150 MeV sq cm/g or greater. The frequency of visual observations near the geomagnetic poles corresponds to calculated abundances of ions with LET greater than 5 keV per micrometer in tissue. Nuclear collisions of fast protons on C, N, and O in the retina or the abundance of stopping protons can explain the low frequency of events in the SAA for this mission in comparison with the high frequency during Skylab IV at 443 km altitude.
