Abstract: The invention relates to a device and a method for the connection and linear separation of two elements, such as the two stages of a spacecraft, consisting in using a tube containing a pyrogenic-type material and a glue arranged around the tube, particularly in contact with the elements. The pyrotechnic triggering of the pyrogenic material causes heating and the melting or carbonisation of the glue and the separation of the two elements.

Abstract: A system for separating composites of a space launch vehicle, comprising non-pyrotechnic separating modules distributed between the composites to be separated and a device for activating the separation modules, which can generate the simultaneous activation of all of the separating modules. The activation device consists of a source of compressed gas, the outlet of which is connected to each separation module.

Abstract: To enable a local connection with separation on command, a connection device (20) comprises a first base plate (24), a first connection wall (22) forming a protuberance from the first base plate (24) and having an internal surface (22A) delimiting an internal volume (V) located on the side of the first base plate, on a first side, and a first connection surface (22B), a second base plate (28), a second connection wall (26) fixed to the second base plate on a second side and with a second connection surface (26A) covering the first connection wall (22) so as to form a space (S) between the first and second connection surfaces, a bonding layer (30) arranged in the space and extending along at least two distinct directions, and a heat generating material (32) arranged in an internal volume so as to enable heating of the bonding layer.

Abstract: A shaped charge comprising a containment shell, an explosive charge placed in the containment shell and having a V-shaped surface, a fuse placed behind the explosive charge, and a layer of projection material placed in front of the V-shaped surface of the explosive charge. A layer of pyrogenic material is used for heating the projection coating. This pyrogenic material can also be mixed with the explosive charge.

Abstract: A method and device enable the linear separation of two elements attached to each other through two connecting surfaces which are conical in this example, of a first element and a second element respectively, using thermite placed on the other side of the wall of the outer element, facing a connecting arrangement placed between both connecting surfaces. An electrical triggering of the thermite causes a quick and local warming-up, at the connecting arrangement which, after melting, enables both elements to be separated.

Abstract: A method and device enable the linear separation of two elements attached to each other through two connecting plates of the first element and the second element respectively. An arrangement connecting and separating the two connecting plates are mixed and comprise a layer. The connecting arrangement comprises soldering, glue, or resin, whereas the separating arrangement comprises thermite. These elements can also be layered rather than mixed. An electrical triggering of this assembly causes its quick and local warming-up and thus enables both of these elements to be separated.

Abstract: A method and device enable the linear separation of two elements attached to each other, through two respective connecting surfaces of these two elements. A connecting layer is placed between both connecting parts. Thermite is used to melt this connecting layer. The thermite can be placed on the other side of the first connecting part towards the first element, a heat protecting plate completing this assembly. The thermite can also be placed in grooves provided on the connecting surface of the second connecting plate to be directly in contact with the connecting layer.

Abstract: The invention relates to a method and a device allowing the separation of two stages of an aeronautical vehicle, without affecting the structure of the two stages. The device consists mainly of a connecting ring (13) secured to the two stages of the aeronautical vehicle and comprising a cutting ring (20) on the inner surface (13A) thereof, which contains a mixture of thermite and an intermetallic composition. The triggering of the latter allows the heating and melting of part of the ring (13), which separates into two parts. The invention can be applied to an aeronautical launcher.
