The system (S) to separate at least two mechanical elements (EE), comprises a holding device comprising a connecting screw integral with a mechanical element (E) and held by a nut segmented in portions () arranged between the connecting screw and an outer envelope integral with the other mechanical element (E), the system (S) comprising a force generator generating a thrust force (F) in a longitudinal direction (X-X) and comprising an energy accumulator comprising a sealed chamber with a colloid of a porous matrix and liquid, the chamber deforming in the longitudinal direction (X-X) to adapt to the change from a compressed to a decompressed state in order to generate the force (F), and an activatable actuating element to, either apply a predetermined pressure to the chamber to keep the colloid in the compressed state, or not apply the predetermined pressure to allow the change in state of the colloid.

Electromechanical point separation system

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.

Connection device with separation controlled by non-pyrotechnic thermal effect with reduced reaction time

An electromechanical actuator (), comprising a movable member () provided with connecting means () and translationally movable with respect to a frame (), and an energy absorbing-dissipating structure () located on a strain path between said connecting means () and said frame () and comprising a porous capillary matrix () having an apparent porosity and an associated liquid () having a wetting angle higher than 90 degrees relative to said matrix () and selected such that part of said liquid () penetrates the pores of said matrix (), when said chamber is subjected to a pressure equal to or higher than a first pressure level P1, and is spontaneously rejected off the pores of said matrix () by capillary action, when said structure is subjected to a pressure lower than a second pressure level P2 itself lower than said first pressure level P1.
