<p>In order to fill the cryogenic propulsions of a launcher with propellants, until lift-off of the launcher, a device is proposed including a tube segment (20) connecting the pipelines on the ground and onboard the launcher (12). A weakened region (22) of this tube segment is automatically broken during lift-off, by a mechanism (24, 38) applying a tensile force on the segment. This mechanism comprises several sets of connecting rods (26, 28) bearing on the tube segment on either side of the weakened region, and a lever (63) articulated on each set of connection rods (26, 28) and ending in a hemispherical bearing zone (65). This bearing zone bears in ball-joint manner on a bearing surface (59) with circular arc cross-section, formed in a sleeve tube (38) which is fixed with respect to the ground. <IMAGE></p> |
