Abstract (en)

[origin: EP2495399A1] The housing (12) has a segmented shell (22) that is structured and operable to enclose a row of blades (24) and supported by a structural wall. Elastically deformable units (30) are positioned between the wall and segments of the shell so as to radially displace the segments in the event of contact with tips of the blades of a rotor and in the event of misalignment of a rotation axis of the rotor relative to an axis of the housing. The deformable units comprise elements made of elastically deformable materials e.g. elastomeric materials. An independent claim is also included for an axial turbomachine compressor.
