Anti-blackout flying suits

Abstract

For the European manned space activities an EVA space suit system was being developed in the frame of the Hermes Space Vehicle Programme of the European Space Agency (ESA). The space suit was to serve the needs for all relevant extravehicular activities for the Hermes/Columbus operations planned to begin in 2004.For the present Russian manned space programme the relevant EVAs are performed by the Orlan-DMA semi-rigid space suit. The origin of its development reaches back to the 1970s and has since been adapted to cover the needs for extravehicular activities on Salyut and MIR until today. The latest modification of the space suit, which guaranteed its completely self-contained operation, was made in 1988. However, Russian specialists considered it necessary to start developing an EVA space suit of a new generation, which would have improved performance and would cover the needs by the turn of the century and into the beginning of the next century.Potentially these two suit developments could have a lot in common based on similarities in present concepts.As future manned space activities become more and more an international effort, a safe and reliable interoperability of the different space suit systems is required. Based on the results of the Munich Minister Conference in 1991, the European Space Agency and the Russian Space Agency agreed to initiate a requirements analysis and conceptual design study to determine the feasibility of a joint space suit development, EVA 2000.The design philosophy for the EVA 2000 study was oriented on a space suit system design of: •—space suit commonality and interoperability•—increased crew productivity and safety•—increase in useful life and reduced maintainability•—reduced development and production cost.The EVA 2000 feasibility study was performed in 1992, and with the positive conclusions for EVA 2000, this approach became the new joint European/Russian EVA Suit 2000 Development Programme.This paper gives an overview of the results of the feasibility study and presents the joint requirements and the proposed design concept of a jointly developed European/Russian space suit.
