Abstract

L'invention concerne un engin spatial (2) comprenant une caisse (4) ayant une face (16, 18), un radiateur (22, 23) porté par ladite face, et un dispositif d'isolation thermique (28) porté par le radiateur. Le dispositif d'isolation thermique comprend : - un premier dispositif écran (30) apte à recouvrir une première zone (32) dudit radiateur, ledit premier dispositif écran (30) comprenant une feuille thermiquement isolante et souple, et au moins deux ressorts propres à produire un effort de réaction constant, lesdits ressorts étant préformés de manière à s'enrouler sur eux-mêmes au repos et étant fixés sur la feuille isolante, lesdits ressorts ayant chacun une extrémité fixée sur le radiateur une extrémité libre; et - un dispositif de traction (34) propre à tirer sur l'extrémité libre desdits ressorts pour que la feuille recouvre la première zone et à libérer l'extrémité libre pour exposer la première zone vers l'espace.The invention relates to a spacecraft (2) comprising a body (4) having a face (16, 18), a radiator (22, 23) carried by said face, and a thermal insulation device (28) carried by the radiator. The thermal insulation device comprises: - a first screen device (30) able to cover a first zone (32) of said radiator, said first screen device (30) comprising a thermally insulating and flexible sheet, and at least two springs adapted to producing a constant reaction force, said springs being preformed so as to wind on themselves at rest and being fixed on the insulating sheet, said springs each having an end fixed on the radiator a free end; and a pulling device (34) capable of pulling on the free end of said springs so that the sheet covers the first zone and to release the free end to expose the first zone towards the space.
