Title
(EN) DEVICE FOR DAMPING FLUID IN A RESERVOIR, IN PARTICULAR OF A SPACECRAFT
(FR) DISPOSITIF D'AMORTISSEMENT DE FLUIDE DANS UN RÉSERVOIR, EN PARTICULIER D'UN ENGIN SPATIAL
Abstract
(EN)
The device (1) for damping a fluid intended for a reservoir (6) in particular of a spacecraft comprises a framework (3) provided with at least one ring (8) and with a plurality of rods (7), each of said rods (7) being fastened by a first end around said ring (8), said device (1) comprising a net (2) arranged on the plurality of rods (7) and around the ring (8), the net (2) comprising a mesh adapted to the viscosity of the fluid to be damped so as to damp movements of said fluid.
(FR)
Le dispositif (1) d'amortissement d'un fluide destiné à un réservoir (6) en particulier d'un engin spatial comporte une armature (3) pourvue d'au moins un anneau (8) et d'une pluralité de tiges (7), chacune desdites tiges (7) étant fixée par une première extrémité autour dudit anneau (8), ledit dispositif (1) comportant un filet (2) agencé sur la pluralité de tiges (7) et autour de l'anneau (8), le filet (2) comprenant un maillage adapté à la viscosité du fluide à amortir de manière à amortir des mouvements dudit fluide.
