Abstract

Pour éviter l'éclatement violent de l'enceinte (2) d'un propulseur contenant du propergol (4) lors d'un incendie accidentel de son environnement, on fixe sur cette enceinte, une composition pyrotechnique (5, 6) qui échauffe localement l'enceinte lors de cet incendie, et fragilise donc cette enceinte, qui s'ouvre à cet endroit avant que la pression intérieure soit trop importante, ce qui évite la fragmentation de l'enceinte et la projection violente de tels fragments.

Figure 00000001
To avoid the violent bursting of the enclosure (2) of a propellant containing propellant (4) during an accidental fire in its environment, a pyrotechnic composition (5, 6) is fixed on this enclosure which heats up locally the enclosure during this fire, and therefore weakens this enclosure, which opens at this location before the internal pressure is too great, which avoids the fragmentation of the enclosure and the violent projection of such fragments.
