Abstract:
1. A containment system for containing fragments of a centrifugal compressor impeller resulting from a burst, the centrifugal compressor impeller rotating about an axis, the system comprising: a containment element having a circumferential surface at least partially surrounding the centrifugal compressor impeller in proximity thereof, and first and second radial surfaces extending substantially radially with respect to the axis, the containment element including an inner shroud and an outer shroud extending from a diffuser ring; first and second walls extending on opposite sides of the containment element; first means for frangibly connecting the containment element to the first wall through the first radial surface; and second means for frangibly connecting the containment element to the second wall through the second radial surface, the first and second means rupturing upon being subjected to a load mainly produced by a translational motion of at least one of the fragments impacting the circumferential surface such as to separate the containment element from the first and second walls,
