Beschreibung
Zusammenfassung:	Space system (1) comprising a structure (2) formed by structure components (3), an on-board equipment (5) carried by the structure (2), and a passive device designed to facilitate demise of the space system (1) during re-entry into the Earth's atmosphere. The passive device comprises connecting members (4) designed to stably connect the structure components (3). The connecting members (4) comprise at least a portion made of a primer material with characteristics such as to decay at re-entry altitudes higher than those at which the current connecting members melt so as to make unstable the connection created by the connecting members (4) to such an extent as to early triggering demise of the structure (2) of the space system (1) during re-entry into the Earth's atmosphere. La présente invention concerne un système spatial (1) comprenant une structure (2) formée par des composants de structure (3), un équipement embarqué (5) porté par la structure (2), et un dispositif passif conçu pour faciliter la disparition du système spatial (1) pendant la rentrée dans l'atmosphère terrestre. Le dispositif passif comprend des éléments de raccordement (4) conçus pour raccorder de façon stable les composants de structure (3). Les éléments de raccordement (4) comprennent au moins une partie constituée d'un matériau d'apprêt ayant des caractéristiques telles que la décomposition à des altitudes de rentrée supérieures à celles auxquelles les éléments de raccordement actuels fondent de manière à rendre instable le raccordement créé par les éléments de raccordement (4) à un degré permettant la disparition précoce de la structure (2) du système spatial (1) pendant la rentrée dans l'atmosphère terrestre.
