Development of a Zero-Prebreathe Spacesuit

Abstract

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.
