Abstract

The device has a linear pyrotechnic charge (5) placed in a flattened deformable tube (6), where a space is provided between the charge and the tube. The tube is deformed by the combustion of the charge, where the speed of combustion is lower than 3000 meter/second. The deformation of the tube permits a structure (3) to be ruptured at the minimum thickness level, where the structure has minimum thickness at the level of a groove (4).
