  • Device to minimize the explosive effects of a metal casing in the event of accidental internal overpressure
    Publication number: 20020020323
    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.

  • Device to control the behavior of a metal casing containing spontaneously inflammable material in the event of external fire
    Publication number: 20020020454
    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.
