Skylab EVA system development

Abstract

The Skylab EVA hardware design from initial conceptual development to final flight configuration is reviewed, the major concepts which were considered during design evolution are identified, and the reasons for the acceptance or rejection of these concepts are discussed. Man/system simulations played a vital part in the decision-making process. The types of developmental simulation used are discussed, as well as their role in providing design information. The developmental protocol of interleaving analyses and simulations on an iterative basis provided Skylab with a conservative, flexible, and simple EVA system which was effective not only for the nominal mission but for many contingency activities as well.
