Abstract: The invention relates to a hollow structural connecting rod (1) including a first end fitting (8a), a second end fitting (8b), as well as a hollow main portion (10) situated between the two end fittings. According to the invention, it includes first and second connecting rod elements (2a, 2b) integrally joined to one another and having, respectively, a first hollow shank (6a) made in one piece together with the first end fitting as well as a second hollow shank (6b) made in one piece with the second end fitting, the first and second connecting rod elements being joined by means of a joint (4) situated at mid-length on said connecting rod, and preferably being produced via flow-turning. Particular application to an assembly system intended to be interposed between an aircraft engine mounting structure and an engine.

Abstract: To prevent the violent bursting of the casing of a thruster containing propergol during an accidental fire in its vicinity, a pyrotechnic composition (5, 6) is attached to this casing. This pyrotechnic composition locally heats the casing during this fire, and therefore embrittles this casing which opens at this place before the internal pressure becomes excessive. This prevents the fragmentation of the casing and the bursting out of the fragments.

Abstract: To prevent the sudden explosion of a casing containing a combustible material such as propergol in the event of fire in the vicinity, with the violent outburst of big splinters, the invention provides for relatively embrittled zones in the casing, in the form of holes plugged by plugs made of a material that melts more easily than the material of the casing.
