The flywheel containment device (2) includes a shaft (4), defining an axis of rotation, and a flywheel (6) having an annular shaped cross section perpendicular to the axis of rotation. The flywheel (6) is connected to the shaft (4) and has an outer diameter (5) and an inner diameter (3). The containment device (2) also comprises an annular shaped honeycomb structure (8) with an annular shaped honeycomb layer (10) having an outer diameter and an inner diameter greater than the outer diameter of the flywheel (6). The honeycomb layer (10) comprises a plurality of pores (11) that are open on the inner diameter of the honeycomb layer (10) to trap dust created if the flywheel (6) fails. The honeycomb layer (10) is positioned around the outer diameter of the flywheel (6) such that the honeycomb structure (8) is independent from the flywheel (6). The device (2) further includes means for supporting the honeycomb structure (8) such that the honeycomb structure (8) is capable of rotating independently from the flywheel (6). A containment vessel (18) is also positioned around the outer diameter of the honeycomb structure (8). |
