A shroud for a centrifugal compressor having a rotation axis, the shroud having a wall curved radially outwardly from an axially oriented inlet to an outlet end, a structural member having a flange at the outlet end, and an abradable insert of Greek Ascoloy exposed on an inner face of the wall.
A gas turbine engine having, in serial flow communication, a compressor section, a combustor, and a turbine section, the compressor section having a centrifugal compressor, the centrifugal compressor having a rotor rotatably mounted within an engine casing for rotation around a rotation axis, and a shroud having a wall curved radially outwardly from an axially oriented inlet to an outlet end, a structural member having a radially-oriented flange at the outlet end, the flange connecting the shroud to the engine casing, and an abradable exposed layer of Greek Ascoloy facing the rotor.
A method of operating a gas turbine engine including:
- compressing air along a gas flow path including rotating a rotor of a centrifugal compressor inside a shroud, the shroud having a wall curved radially outwardly from an axially oriented inlet to an outlet end and having an abradable exposed layer of Greek Ascoloy facing the rotor, and a structural member.
