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.

Gas turbine engine sealing structure

A turbine vane ID support system usable to support the ID of a turbine vane and including a transition seal system and a turbine vane ID forward rail seal system. The transition seal system may seal the turbine vane ID support body to a transition, and the turbine vane ID forward rail seal system may seal the turbine vane ID support body to a turbine vane. Use of the transition seal system and the turbine vane ID forward rail seal system eliminates the problems inherent with conventional seals used to seal transitions directly to turbine vanes. The turbine vane ID support system may also be configured such that the turbine vane ID support system may be removed to facilitate removal of turbine vanes and blades for repair or replacement.

Turbine vane ID support

A support for the first row turbine vanes () in a gas turbine engine, the support including a support framework (). The support framework () includes an outer vane carrier (), and an inner vane carrier () connected to the outer vane carrier () by a plurality of struts (). The outer vane carrier () is mounted to an inner casing () of the engine and the struts () support the inner vane carrier () in cantilevered relation to the outer vane carrier (). An aft outer flange () of each first row vane () is supported on the outer vane carrier () and a forward inner flange () of the vane () is support on the inner vane carrier ().
