Abstract

Abstract Translated from French L'invention concerne un conteneur à structure sphéroidale aplatie aux pôles. The invention relates to a container with a spheroidal structure flattened at the poles. La structure est formée de fuseaux (1) assemblés selon leurs bords. Des renforts méridiens monodirectionnels (4) sont fixés ponctuellement sur les lignes d'assemblage des fuseaux. Les fuseaux sont en un matériau à faible module élastique et à grande capacité d'allongement plastique et les renforts méridiens en un matériau à haut module élastique. Une surpression à l'intérieur de la structure lui fait prendre la forme d'une sphéroïde aplatie aux pôles. The structure is formed of spindles (1) assembled along their edges. Monodirectional meridian reinforcements (4) are fixed punctually on the assembly lines of the spindles. The spindles are made of a material with low elastic modulus and a high capacity for plastic elongation and the meridian reinforcements are made of a material with high elastic modulus. An overpressure inside the structure makes it take the form of a flattened spheroid at the poles. Application aux ballons fermés et aux réservoirs pressurisés. Application to closed tanks and pressurized tanks.
