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.

Method and device for linear connection and separation of two elements, with offset energy means

The temporary connection of two elements ( ) is ensured by U-shaped connecting components ( ) held in place by a moving part ( ). A pyrotechnic composition ( ) is housed between two shoulders ( ) situated respectively on the first of the elements ( ) and on the moving part. Igniting the pyrotechnic composition ( ) causes the moving part ( ) to slide over the first element ( ). The connecting components ( ) are released and the connection between the elements ( ) is eliminated without breaking any parts.
