COMPRESSOR SECTION OF GAS TURBINE ENGINE INCLUDING HYBRID SHROUD WITH CASING TREATMENT AND ABRADABLE SECTION

A gas turbine engine includes a shroud (150) with an abradable section (164) and a non-abradable section (166) that cooperatively define a shroud surface. The gas turbine engine also includes a rotor that is supported for rotation within the shroud to generate an aft axial fluid flow. The rotor incl...

Beschreibung
Zusammenfassung:	A gas turbine engine includes a shroud (150) with an abradable section (164) and a non-abradable section (166) that cooperatively define a shroud surface. The gas turbine engine also includes a rotor that is supported for rotation within the shroud to generate an aft axial fluid flow. The rotor includes a blade with a blade tip (132) that is crowned and that opposes the abradable section and the non-abradable section of the shroud surface. A crown area (172) of the blade tip opposes the abradable section. A casing treatment feature (186) is provided in the non-abradable section of the shroud to oppose the blade tip of the rotor.
