Abstract
(DE) Die Erfindung betrifft eine Raumfahrzeugmembran (2), die selbsttragend und flexibel ist. Die Raumfahrzeugmembran (2) weist ein Substrat (5) aus einem Fluorpolymer auf. Des Weiteren verfügt die Raumfahrzeugmembran (2) über eine Siliziumoxydschicht (6; 7). Die Siliziumoxydschicht (6; 7) schützt das Substrat (5) gegenüber Beeinträchtigungen infolge atomaren Sauerstoffes in einem niedrigen Erdorbit. Des Weiteren betrifft die Erfindung ein Photovoltaik-Raumfahrtmodul (1) mit einem Photovoltaik-Element (3), ein Widerstandssegel, eine reflektierende Membranantenne oder ein reflektierendes Solarsegel.
(EN) The invention relates to a spacecraft membrane (2) which is self-supporting and flexible. The spacecraft membrane (2) has a substrate (5) made of a fluoropolymer. Furthermore, the spacecraft membrane (2) has a silicon oxide layer (6; 7). The silicon oxide layer (6; 7) protects the substrate (5) from impairments as a result of atomic oxygen in a low earth orbit. The invention also relates to a photovoltaic space-travel module (1) having a photovoltaic element (3), to a drag sail, to a reflective membrane antenna or to a reflective solar sail.
(FR) L'invention concerne une membrane (2) de véhicule spatial qui est autoportante et flexible. La membrane (2) de véhicule spatial comprend un substrat (5) constitué d'un polymère fluoré. La membrane (2) de véhicule spatial comprend en outre une couche d'oxyde de silicium (6, 7). La couche d'oxyde de silicium (6, 7) protège le substrat (5) contre des altérations dues à l'oxygène atomique dans une orbite terrestre basse. L'invention concerne en outre un module spatial photovoltaïque (1) comprenant un élément photovoltaïque (3), une voile de résistance, une antenne à membrane réfléchissante ou une voile solaire réfléchissante.
