  • Patent number: 11667409
    Abstract: A separation device for a spacecraft or launcher comprising a nut divided into at least two nut portions locked to each other by a locking device in a locking position. A releasing device is arranged to switch the locking device from the locking position to a releasing position. The separation device comprises at least two bearing elements arranged between the locking device and the nut. The nut comprises an outer envelope surface which comprises as many indentations as the number of bearing elements and locking surfaces between the indentations. In the locked state each bearing element is jammed between the locking surface and an inner envelope surface of the locking device and in the released state each bearing element is positioned facing the indentations.

  • Patent number: 11661216
    Abstract: The invention relates to a separation device for a spacecraft or launcher. The separation device includes an inner housing divided into at least two portions locked to each other by a locking device in a locking position. The locking device is arranged to move between a locking position and a releasing position. The separation device includes an initiator including means for providing high pressure fluid to an expansion chamber when the separation device is switched from a locked state to a released state. The high pressure fluid in an expansion chamber moves the locking device from the locking position to the releasing position when the separation device is switched from the locked state to the released state. The separation device includes a dampening arrangement arranged to attenuate a peak load when the separation device is switched from the locked state to the released state.

  • Patent number: 6648543
    Abstract: A flange (1) for a space vessel (2), which flange (1) is arranged so as to reduce a shock or impact wave that occurs upon the release of a coupling (5). The coupling (5) is intended to impart a radially inwardly acting force to hold together two separable space vessel parts (3, 4) via two flanges (1, 6) belonging to respective space vessel parts (3, 4). The first flange (1) comprises at least one weakened point (9) so that it has a substantially broken annular shape, in order to thus reduce its energy-absorbing capacity when it is bent inward by the force (F).
