Abstract: A shroud retention system may generally include a shroud hanger and first and second hooked components extending from an outer hanger wall of the hanger. The first hooked component may include a first wall extending from the outer hanger wall and a first rail extending from the first wall. The second hooked component may include a second wall extending from the outer hanger wall and a second rail extending from the second wall. In addition, the system may also include a shroud segment having a shroud wall configured to be positioned radially between the outer hanger wall and the first and second rails. Moreover, the system may include a retention spring positioned within a radial space defined between the outer hanger wall and the first and second rails that is configured to apply a radial spring force against the shroud segment.

Abstract: A shroud segment assembly for use within a turbine shroud of a gas turbine engine may generally include a forward shroud portion having a forward outer arm and a forward inner arm extending from a forward wall and an aft shroud portion having an aft outer arm and an aft inner arm extending from an aft wall. Additionally, the shroud segment assembly may include a first expansion joint positioned between the forward and aft shroud portions such that the first expansion joint extends circumferentially between the forward outer arm of the forward shroud portion and the aft outer arm of the aft shroud portion and a second expansion joint positioned between the forward and aft shroud portions such that the second expansion joint extends circumferentially between the forward inner arm of the forward shroud portion and the aft outer arm of the aft shroud portion.

Abstract: A shroud retention system may include a shroud hanger having an outer hanger wall that defines a clip groove including a narrow groove portion and an enlarged groove portion, with the enlarged groove portion defining a radial height that is greater than a radial height of the narrow groove portion. The system may also include a shroud segment having a shroud wall and a retention clip configured to couple the shroud segment to the shroud hanger. The retention clip may include an inner rail, an outer rail and a clip wall extending radially between the inner and outer rails. The inner rail may be configured to extend along an inner surface of the shroud wall. The outer rail may include a narrow rail portion configured to be received within the narrow groove portion and an enlarged rail portion configured to be received within the enlarged groove portion.
