Kurzfassung
The increasing number of rocket-launches and satellite constellations has heightened concerns over space debris and the risks associated with uncontrolled atmospheric re-entry. Design for Demise (D4D) aims to mitigate these risks by ensuring satellite structures disintegrate at high altitudes, reducing debris casualty area (DCA). This study investigates novel demisable joint concepts for primary satellite structures, utilizing additively manufactured inserts complemented by passive ejection mechanisms such as Shape Memory Alloy (SMA) actuators and compression springs. Using ESA’s Sentinel-6 (S6) mission as a reference, hybrid-material joints were designed, analyzed, and tested. Simulations demonstrated their ability to withstand launch loads. Re-entry analysis and thermal simulations indicated structural breakup at altitudes up to 115 km, achieving a 60% reduction in DCA area compared to the reference configuration without demisable joints. Physical prototypes tested at DLR facilities validated these findings. The results demonstrate the effectiveness of demisable joints in enhancing satellite structural breakup during re-entry, contributing to improved space debris mitigation.
