    An evaluation of Orbital Workshop passive thermal control surfaces (1974)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: The optical properties of selected Orbital Workshop thermal control surfaces are discussed from the time of their installation through the end of the Skylab missions. The surfaces considered are the goldized Kapton tape on the habitation area sidewall, the S-13G white paint on the Workshop aft skirt, and the multilayer insulation system on the forward dome of the habitation area. A quantitative assessment of the effects of exposure to the ascent and orbital environments is made including the effects of rocket exhaust plume contamination. Although optical property degradation of the external surfaces was noted, satisfactory thermal performance was maintained throughout the Skylab missions.

    On the e-process - Its components and their neutron excesses (1974)
    In:  Other Sources
    Details
    Publication Date: 2019-06-27
    Description: The pattern of abundances within the iron-abundance peak of the solar system is analyzed for various Cr, Fe, and Ni abundances, and a method is developed for finding the best fit to a given set of abundances with a chosen number of zones, i.e., mass contributions characterized by differing values of eta. This material can be synthesized by a superposition of e-process compositions in a low-eta region (eta = 0.003) and a high-eta region (eta = 0.065 -0.080) with at least 85% coming from the low-eta region. Addition of a third eta zone is unproductive. The applicability of the particle-poor freeze out is discussed in the light of these abundances, and the results of employing different numbers and types of zones are interpreted as an indication of the relative abundances themselves. Ejection of the low-eta zones is of great interest in gamma-ray astronomy and for empirical testing of theories of nucleosynthesis. The distribution of high zones should give important information about the formation of collapsed remnants.

    The C-12/C-13 ratio in stellar atmospheres. II - CN and CO in alpha Orionis (1974)
    In:  Other Sources
    Details
    Publication Date: 2019-06-27
    Description: The isotopic abundance ratio C-12/C-13 for the M supergiant alpha Orionis is derived from photoelectric high-resolution scans of the CN 2-0 red system and high-resolution interferometric spectra of the CO second-overtone bands. The two molecules yield consistent results and the final value for the C-12/C-13 ratio is 7.0 plus or minus 1.5. Rationale is offered for the causes contributing to an earlier suggestion that C-12/C-13 ratios from CO and CN were in disagreement.

    Six-man, self-contained carbon dioxide concentrator system (1974)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: A six man, self contained electrochemical carbon dioxide concentrating subsystem was successfully designed and fabricated. It was a preprototype engineering model designed to nominally remove 6.0 kg (13.2 lb) CO2/day with an inlet air CO2 partial pressure of 400 N/sq m (3 mm Hg) and an overcapacity removal capability of 12.0 kg (26.4 lb) CO2/day. The design specifications were later expanded to allow operation at space station prototype CO2 collection subsystem operating conditions.

    Life support subsystem monitoring instrumentation (1974)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: The recognition of the need for instrumentation in manned spacecraft life-support subsystems has increased significantly over the past several years. Of the required control and monitoring instrumentation, this paper will focus on the monitoring instrumentation as applied to life-support subsystems. The initial approach used independent sensors, independent sensor signal conditioning circuitry, and independent logic circuitry to provide shutdown protection only. This monitoring system was replaced with a coordinated series of printed circuit cards, each of which contains all the electronics to service one sensor and provide performance trend information, fault detection and isolation information, and shutdown protection. Finally, a review of sensor and instrumentation problems is presented, and the requirement for sensors with built-in signal conditioning and provisions for in situ calibration is discussed.

    Helicopter flight investigation to determine the effects of a closed-circuit TV on performance of a precision sling-load handling task (1974)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: Helicopter sling-load operations have been limited during hover and low-speed flight by the degree of precision achieved by the pilot/helicopter/sling-load combination. Previous attempts to improve precision have included stabilization of the load and helicopter and the addition of a pilot station directly facing the load. In these tests, use of a closed-circuit TV as a display that would permit sling-load delivery and placement by the forward-facing pilot was evaluated using a CH-54B helicopter. In all, three test cases were documented, which included the following: (1) forward-facing pilot using the TV display, (2) forward-facing pilot using verbal commands from a load-facing observer, and (3) aft-facing pilot using direct visual cues. The results indicate that a comparable level of performance was achieved for each test case; however, an increase in pilot workload was noted when the TV system was used.

    Near-earth cosmic dust results from S-149 (1974)
    In:  Other Sources
    Details
    Publication Date: 2019-07-27
    Description: Three space exposures (34, 46 and 33 days) of thin films and polished metal plates with a total area of 0.12 sq m per exposure were carried out during Skylab via the S-149 experiment. Study of the materials recovered indicates that the S-149 experiment contains important information concerning cosmic dust in the near-earth vicinity. Craters and penetration holes have been found ranging from 135 micron diameter to less than 0.5 micron. A cosmic dust flux curve in the mass range from 10 to the minus 16th to 10 to the minus 7th grams is presented. Evidence is given concerning the directional characteristics of the particles and their breakup in near-earth space is presented.

    Publication Date: 2011-08-16
    Description: Determinations of interplanetary sector structure for the years 1970-1972 reveal the persistence of sector patterns during the decreasing portion of the solar cycle. The simple two-sector pattern of 1969 persists through 1970 but develops greater complexity in 1971-1972.-

    The ethynyl radical C2H - A new interstellar molecule (1974)
    In:  Other Sources
    Details
    Publication Date: 2011-08-16
    Description: Four new interstellar lines have been detected near 87.3 GHz. Based on laboratory ESR data these lines have been positively defined as hyperfine components of the lowest rotational transition of the ethynyl radical C2H. The observations gave precise values for the C2H rotation, spin-doubling, and hyperfine constants. C2H is probably one of the most abundant interstellar polyatomic molecules yet detected.
