摘要： The invention relates to a cut-off device comprising: a conductive element and a movable piston, the piston being able to move between a first position in which the current passes in the conductive element and a second position in which the current is cut off, the piston being configured to break the conductive element when moving from its first position to its second position, the piston being positioned in a receiving cavity of a receiving element when said piston is in its second position,
characterized in that the receiving element further comprises at least one additional cavity separate from the receiving cavity and linked to said receiving cavity by at least one channel, said at least one channel being open when the conductive element is broken by the piston.-

摘要： A space aircraft including a fuselage, two wings arranged on either side of the fuselage, and two nacelles arranged at the ends of the wings and each carrying a horizontal tail and a vertical tail, the fuselage having a cross section of variable size along the longitudinal axis with a maximum cross section being located in a longitudinal position located in front of the longitudinal position of the leading edges of the wings at the fuselage, making it possible in particular to help prevent the space aircraft from losing longitudinal static stability, the space aircraft thus having an optimized design and architecture which are suitable for the severe conditions encountered by such a space aircraft, in particular during atmospheric re-entry.

摘要： In order to provide a temporary connection between two structure elements, such as two parts of a space launcher or of another type of spacecraft or aircraft, a connection device with controlled separation comprises a thermally breakable layer, two thermal containment layers, between which the thermally breakable layer is arranged, and an electrically conductive element arranged between the two thermal containment layers in such a way as to heat the thermally breakable layer using the Joule effect when an electric current passes through the electrically conductive element.

摘要： A partially polymerised thermohardenable connection part and to methods for producing and assembling such a connection part. The connection part for connecting two mechanical parts is thermohardenable and is partially polymerised in such a way as to be rigid at room temperature and able to be subjected to a subsequent polymerisation, the connection part being thus both sufficiently rigid to be able to be manipulated and brought into contact with at least one of the two mechanical parts which it is to interconnect and able to be subjected to a subsequent additional polymerisation in order to achieve its final polymerised state, the material of the connection part being rendered sufficiently soft during the additional polymerisation that it can adapt to the form of at least one of the mechanical parts to which the connection part must be connected.
