    Worldwide surface extremes (1973)
    In:  CASI
    Details
    Publication Date: 2006-04-02
    Description: Information needed to fabricate, transport, test, and launch space vehicles requires statistical meteorological data for various geographical areas. A brief review of world surface extremes is presented that illustrates the large extremum values that occur in some global areas and compares them with those currently used in space vehicle design.

    Atmospheric composition (1973)
    In:  CASI
    Details
    Publication Date: 2006-04-02
    Description: The earth's atmosphere is made up of a number of gases in different relative amounts. Near sea level and up to about 90 km, the amount of these atmospheric gases in clean, relatively dry air is practically constant. Four of these gases, nitrogen, oxygen, argon, and carbon dioxide, make up 99.99 percent by volume of the atmosphere. Two gases, ozone and water vapor, change in relative amounts, but the total amount of these two is very small compared to the amount of the other gases. The atmospheric composition shown in a table can be considered valid up to 90 km geometric altitude. Above 90 km, mainly because of molecular dissociation and diffusive separation, the composition changes.

    Atmospheric electricity (1973)
    In:  CASI
    Details
    Publication Date: 2006-04-02
    Description: Atmospheric electricity must be considered in the design, transportation, and operation of aerospace vehicles. The effect of the atmosphere as an insulator and conductor of high voltage electricity, at various atmospheric pressures, must also be considered. The vehicle can be protected as follows: (1) By insuring that all metallic sections are connected by electrical bonding so that the current flow from a lightning stroke is conducted over the skin without any gaps where sparking would occur or current would be carried inside; (2) by protecting buildings and other structures on the ground with a system of lightning rods and wires over the outside to carry the lightning stroke into the ground; (3) by providing a zone of protection for launch complexes; (4) by providing protection devices in critical circuits; (5) by using systems which have no single failure mode; and (6) by appropriate shielding of units sensitive to electromagnetic radiation.

    Distribution of surface extremes in the United States (1973)
    In:  CASI
    Details
    Publication Date: 2006-04-02
    Description: Extreme design environment data are presented for consideration in aerospace vehicle transportation, fabrication, or testing. Values were obtained by using data from weather stations and published meteorological articles. Maps depict snow fall, hail distribution, atmospheric pressure, atmospheric temperature, and surface elevations.

    Fungi and bacteria (1973)
    In:  CASI
    Details
    Publication Date: 2006-04-02
    Description: Spacecraft equipment is usually protected from fungi and bacteria by incorporating a fungicide-bactericide in the material, by a fungicide-bactericide spray, or by reducing the relative humidity to a degree where growth will not take place. A unique method to protect delicate, expensive bearings in equipment was to maintain a pressure (with dry air or nitrogen) slightly above the outside atmosphere (few millibars) within the working parts of the equipment, thus preventing fungi from entering equipment.

    Atmospheric pressure (surface) (1973)
    In:  CASI
    Details
    Publication Date: 2006-04-02
    Description: The total variation of pressure from day to day is relatively small. Rapid but slightly greater variations occur as the result of the passage of frontal systems, while the passage of a hurricane can cause somewhat larger, but still not significant changes for pressure environment design of space vehicles. Surface pressure extremes for various locations and their extreme ranges are given. These data use the results of a study of pressure extremes.

    Thermal (1973)
    In:  CASI
    Details
    Publication Date: 2006-04-02
    Description: One of the more important environmental influences on a vehicle is the thermal environment. Combinations of air temperature, solar radiation, and sky radiation can cause various structural problems. Some example of potential problems are: (1) Heating of one side of the vehicle by the sun while the other side is cooled by a clear sky causes stresses since the vehicle sides will be of different length; (2) the temperature of the fuel influences the volume/mass relationship; and (3) too high a temperature may destroy the usefulness of a lubricant. The heating or cooling of a surface by air temperature and radiation is a function of the heat transfers taking place; therefore, methods of determining these relationships are presented.
