Abstract:

bration, Abrasion, Stability, Space environmen tal conditions, Pressure. Design of Sealing techniques for Spaceships, Satellite vehicles. Near absolute sealing techniques are described for small openings, such as for electrical conductors, and hatches in the walls of flight vehicle cabins. The need for absolute sealing stems from the requirement of a habitable environment in such vehicles for as long as one year under differential pressure and temperature extremes from -100 to 500 F. Considerations underlying selection of suitable seal materials for resistance to space environment are discussed. The mechanical design and material factors are also discussed. Investigations concerned with effect of elastomer permeability upon seal behavior and with techniques for sealing electrical wires and cables are described. Concepts for the four sealing applications considered are described. Recommendations are made regarding actual sealing concepts. Author
