Abstract (en)

The missile body has a cylindrical wall (2) e.g. of steel containing solid fuel propellant (3) and a thermal insulation liner (5), has weakened zones to release internal pressure in the event of a fire in the surrounding area without altering its mechanical properties. The weakened zones can be in the form of orifices (6) plugged with a material which is less resistant than that of the wall. The plug (7) can be made from a material such as tin, with a lower melting point than the missile wall, or it can be fitted by force and ejected by the internal pressure.

Abstract (fr)

Pour éviter l'éclatement brutal d'une enceinte (2) contenant un combustible tel qu'un propergol en cas d'incendie environnant, avec projection violente de gros éclats, l'invention prévoit des zones de fragilisation relative dans l'enceinte, sous forme d'orifices (6) bouchés par des bouchons (7) en matériau plus facilement fusible que celui de l'enceinte. <IMAGE>
