Development of a zero-prebreathe spacesuit

This paper presents the results of a program to develop an improved high pressure (zero-pre-breathe) spacesuit utilizing the latest joint technology as well as materials and processes which are consistent with the space environment and suit production techniques. Other development objectives include: longer life, lower joint torques with increased ranges, improved reproducibility and reliability, facilitated resizing ability and increased overall performance capability when compared to the present Shuttle Orbiter Spacesuit at the higher pressures.

Test evaluation of space station ECLSS maintenance concepts

The Space Station Prototype (SSP) Environmental Control and Life Support System (ECLSS) hardware was designed and built to be maintainable by the flight crew. To achieve this goal, subsystems were designed for ease of component removal and installation, which included accessibility to component fasteners and connectors, adequate tool clearance, minimum fluid loss during changeout, positive capture of loose parts during changeout, replacement by one crewman, and protection of adjacent parts during maintenance. During testing of this hardware, many day-to-day problems arose which allowed the evaluation of the maintenance concepts under actual maintenance conditions. This paper briefly discusses the maintenance objectives of the hardware design. Specific maintenance designs and their test evaluations are discussed. A removable cartridge valve concept for liquid line components and threaded mechanical fittings and V-band couplings for gaseous line components are critiqued. Other maintenance devices are also evaluated.
