Abstract:
1. Temporary connection and pyrotechnic separation device with a longitudinal axis comprising a pyrotechnic expansion tube mounted in a space formed in a connection zone between a first and a second assembly to be separated, the second assembly being formed of a stack of plies bonded together, said stack comprising two outer plies and inner plies, said plies being approximately parallel to the longitudinal direction, the two assemblies being connected to each other by at least one metal part, said metal part being fixed onto the first assembly and bonded onto one of the outer plies of the second assembly, the bonding area between said outer ply and the inner ply adjacent to it being smaller than the bonding area between two inner plies forming a fuse ply, and the bonding area between the metal part and the outer ply is smaller than or equal to the area of the outer ply, such that when the pyrotechnic expansion tube is used, the outer ply becomes delaminated from the adjacent inner ply.
