METHOD AND DEVICE FOR CONNECTING AND SEPARATING TWO ELEMENTS, WITH CONNECTING PLATES

摘要

The method and the device according to the invention allow two elements (1, 2) that are fixed to one another by two respective connecting surfaces (10, 20) belonging to the two elements (1, 2) to be separated linearly. The connecting layer (30) is placed between the two connecting pieces (10, 20). Thermite (15) is used to make this layer of connecting means (30) melt. This thermite may be positioned on the other side of the first connecting piece (10) towards the first element (1), a heat shield plate (17) completing this setup. The thermite may also be placed in groves made on the connecting surface (22) of the second connecting plate (20) so as to be in direct contact with the layer of connecting means (30). Application to the separation of two stages of an aeronautical launcher.
