IAC-13,D3.1,6x17742 PANORAMA OF IDEAS ON STRUCTURE AND MATERIALS FOR THE DESIGN OF A MULTI-MODULAR SPACE STATION AT EML2

摘要

The goal of the article will be to come up with an optimized solution that can answer the question of how to build a space station (named THOR, Trans-lunar Human explORation): fit for Deep Space Habitat. The spacecraft's structure examined here is based around seven cylindrical habitable modules, each one fulfilling a specific function - leisure and daily life, experiments, Extra Vehicular Activity, Space Medical Center - and two extra spherical sections, used both for daily life activities and docking tasks. Taking the challenges and constraints of deep-space environment into account and adding up the effects of solar winds in deep space environment, each module has been put through an accurate analysis to then be optimized during the conceptual design of the spacecraft. Some ideas for the propulsive system layout and overall configuration for the docking system have also been proposed. To make the study at hand as thorough as possible, the research project focus on and examines a wide array of materials used to build spacecraft and stations: metal alloys, composite materials, sandwich honeycomb core, inflatable anti-solar-radiation (at the option of water storage inside), and see-through glass-like materials. Eventually, a conclusive part then try to sum up both structural concepts and material analysis for the final internal and external design of the spacecraft. During the study, many questions about possible innovative solutions arose, and the final chapter summarize them all.
