Abstract
Shrouds and shroud assemblies for gas turbine engines are provided. A shroud includes a shroud body. The shroud body includes a forward surface, a rear surface axially spaced from the forward surface, an inner surface extending between the forward surface and the rear surface, and an outer surface extending between the forward surface and the rear surface and radially spaced from the inner surface. The shroud further includes a flange extending from the shroud body, and a bore hole defined in the flange. The bore hole extends generally circumferentially through the flange between a first opening and a second opening.
Claims11
A shroud assembly for a gas turbine engine, the shroud assembly comprising:
- a hanger, the hanger comprising a hanger body, a forward hanger arm and a rear hanger arm radially outward from the hanger body and spaced apart from each other, and a flange housing extending radially outward with respect to a turbine or compressor blade from an outer surface of the hanger body and located between the forward and the rear hanger arms, the hanger further comprising a bore hole of the hanger extending circumferentially through the flange housing between a first opening and a second opening;
- a shroud, the shroud comprising a shroud body and a flange extending from the shroud body, the shroud further comprising a bore hole of the shroud defined in the flange, the bore hole of the shroud extending circumferentially through the flange between a first shroud opening and a second shroud opening, the flange disposed within the flange housing;
- and
- a pin extending circumferentially through the bore hole of the hanger and the bore hole of the shroud.
A gas turbine engine, comprising:
- a compressor;
- a combustion section;
- a turbine;
- and
- a shroud assembly disposed in one of the compressor or the turbine, the shroud assembly comprising:
- a hanger, the hanger comprising a hanger body, a forward hanger arm and a rear hanger arm radially outward from the hanger body and spaced apart from each other, and a flange housing extending radially outward with respect to a turbine or compressor blade from an outer surface of the hanger body and located between the forward and the rear hanger arms, the hanger further comprising a bore hole of the hanger extending circumferentially through the flange housing between a first hanger opening and a second hanger opening;
- a shroud, the shroud comprising a shroud body and a flange extending from the shroud body, the shroud further comprising a bore hole of the shroud defined in the flange, the bore hole extending circumferentially through the flange between a first shroud opening and a second shroud opening, the flange disposed within the flange housing;
- and
- a pin extending circumferentially through the bore hole of the hanger and the bore hole of the shroud.
