Abstract
A turbine section having a plurality flow path components forming a plurality of guide vane rings and ring segments arranged in axial succession to define a boundary of a hot gas duct. A vane carrier located around the gas duct, and sealing elements extend radially between circumferentially extending grooves in the vane carrier and respective grooves in the flow path components. The sealing elements include radially inner and outer edges, and at least one axially facing side defining a chamfered portion extending to one of the edges to accommodate axial movement of the sealing element about the one edge within a respective groove.
Claims18
An axial flow gas turbine engine arranged about a central axis, comprising:
- a compressor section;
- a combustor section;
- a turbine section having a plurality flow path components forming a plurality of guide vane rings and ring segments arranged in axial succession to define a boundary of a hot gas duct that contains a hot gas flow from the combustor section;
- a vane carrier;
- and
- a sealing element including axially facing sides extending radially between a circumferentially extending groove in the vane carrier and a groove in the flow path components, the sealing element including radially inner and outer edges, and at least one of the axially facing sides defining a chamfered portion extending to one of the edges to accommodate axial movement of the sealing element about the one edge within a respective groove.
An axial flow gas turbine engine sealing system, comprising:
- a vane carrier having a circumferentially extending groove;
- a flow path component ring defining a boundary of a hot gas duct and having a circumferentially extending groove;
- a sealing element including axially facing sides extending radially between the groove of the vane carrier and the groove of the flow path component ring, the sealing element comprising a plurality of arcuate segments located in side-by-side relationship, and
- each of the segments of the sealing element engaged with adjacent segments in overlapping relationship at shiplap joints.
