The energy storage flywheel device (6) includes a plurality of annular shaped composite sections (8) and an annular shaped insert (10). The insert (10) has a specific radial strength substantially greater than the composite sections' specific radial strength. The composite sections (8) and the insert (10) are alternately stacked such that they have a common axis of rotation. They are bonded to each other such that shear stress is transferred between the composite section (8) and insert (10). In some applications, the flywheel (6) may comprise at least one annular shaped metal matrix composite section (8).

Un dispositif de volant d'inertie à stockage d'énergie (6) comprend une pluralité de sections composites de forme annulaire (8) ainsi qu'un élément annulaire (10) inséré entre celles-ci. L'élément inséré (10) est doté d'une résistance radiale spécifique sensiblement supérieure à celle des sections composites. Les sections composites (8) et l'élément inséré (10) sont empilés alternativement de manière à avoir un axe de rotation commun. Ils sont liés l'un à l'autre de façon que les forces de cisaillement soient transférées entre les sections composites (8) et l'élément inséré (10). Dans certaines réalisations, le volant d'inertie (6) peut comprendre au moins une section composite (8) annulaire à matrice métallique.
