The casing has an axial ring (32) arranged coaxial to another axial ring (34), where a centering unit (52) of the latter ring cooperates with a centering surface (54) of the former ring. A set of cuts (58) e.g. festoons and openings, is distributed along circumference of a support (48) of the former ring. The centering unit axially extends from a support (50) of the latter ring to the centering surface through the cuts when the two supports are in contact with each other. A radius (R2) of the centering surface is lower than a radius (R3) of a radial end of the support of the former ring. An independent claim is also included for a turboshaft engine. |
