Abstract: A device for rapidly separating two subassemblies under the action of a pyrotechnic gas generator. The device comprises a segmented nut (17) held by a release sleeve (40) that is movable under the action of the gas generator (15), a drive chamber (64) including an end wall of the release sleeve, a damping chamber (66) communicating with a gas expansion chamber (60), and calibrated passages (70) extending between the damping chamber and the drive chamber.

Abstract: The technical field of the invention is that of devices for connecting and separating objects such as microsatellites with respect to a structure. More specifically, the invention relates to a separation device (1) intended to release a screw (8) which holds two subassemblies of a structure together, this release taking place through the movement of a release ring (5) by virtue of the gases produced by a gas generator (3). The main feature of the separation device (1) according to the invention is that a damping device, achieved by pressurizing a space (19) with the gases emitted by the generator (3), is created in order to decelerate then halt the release ring (5) before it can produce a mechanical shock at the end of its travel.
