Development of a pre-prototype generic work station/restraint system for extravehicular activity

摘要

Present generation work restraints are limiting, either requiring excessive set-up time or dedication of the Remote Manipulator System (RMS) and operator. With the increase of planned Extravehicular Activity (EVA) for Space Station and Satellite servicing, a definite need exists for a portable work restraint that is easily set up and can be operated by one EVA crewman. The purpose of the Generic Work Station/Restraint System (GWS) program was to design, fabricate, test, and deliver a Feasibility Test Unit for NASA's evaluation. Neutral buoyancy testing was used as part of an iterative design process which allowed for changes based on test performance. A flight version of the GWS would make EVA work easier by reducing set-up time, eliminating the need for the RMS and operator, and allowing crewmen to position themselves in place.
