Abstract (en)

The invention relates to a casing (13) of a turbo machine (10), which extends along a machine axis (12) of said turbo machine (10) and coaxially surrounds a rotor (11) of said turbo machine (10) thereby defining an annular hot gas path. Said casing (13) comprises at least one axial section, wherein a plurality of axially extending apertures (16) are provided in the wall of said casing (13) and distributed around its circumference in order to reduce the individual influence of said at least one axial section on an overall radial deformation by reducing thermally induced circumferential stresses in said at least one axial section. Method for manufacturing such a casing and gas turbine comprising such a casing.
