International planetary sunshade concept with a function-integrated and scalable support structure based on coreless filament winding

Abstract Despite all current efforts, climate change is the greatest challenge of 21 st century. Since existing measures will fail to prevent critical tipping points from being reached, in addition terrestrial geoengineering methods, efforts are underway explore new ways implement space-based methods into short-term construction a buffer solution - International Planetary Sunshade (IPSS). The IPSS system reduces solar irradiation mitigating global mean temperature rise while offering sustainable energy supply. developement poses multifaceted challenges only be mastered by collaboration space agencies and private companies, supported society. Therefore, tackling within international roadmaps essential exploit synergies, shorten development time, promote cooperation. An evolutionary concept achieves stepwise Earth independence utilizing lunar resources. feasibility also depends on foil’s supporting structure. lightweight manufacturing technology that meets several criteria, such as scalability, adaptivity, material compatibility, full automation, on-orbit manufacturing, in-situ resource utilization, digital design including function integration, must adopted. Hence, coreless filament winding (CFW) may suitable for realizing demanded mass savings. prerequisite superiority CFW structures an application- material-compliant component fiber net design. Previous experience with cannot directly transferred due changed requirements application. This paper present systematic IPSS, initially exploring support structure discussing segmentation modularity, proposing connection system, implementing integration.
