Abstract
A support for the first row turbine vanes (12) in a gas turbine engine, the support including a support framework (18). The support framework (18) includes an outer vane carrier (34), and an inner vane carrier (36) connected to the outer vane carrier (34) by a plurality of struts (44, 46). The outer vane carrier (34) is mounted to an inner casing (16) of the engine and the struts (44, 46) support the inner vane carrier (36) in cantilevered relation to the outer vane carrier (34). An aft outer flange (94) of each first row vane (12) is supported on the outer vane carrier (34) and a forward inner flange (114) of the vane (12) is support on the inner vane carrier (36).
Claims20
A support for supporting vanes radially within an inner casing in a turbine engine, the vanes located in a hot gas flow from a combustor, on an upstream side, to a turbine section, on a downstream side, the support comprising:
- a framework including an outer vane carrier rigidly supported to an upstream end of the inner casing of the turbine engine, and an inner vane carrier located radially inwardly from the outer vane carrier;
- a strut structure comprising a plurality of circumferentially spaced struts rigidly attached to said outer vane carrier and extending radially inwardly from said outer vane carrier and rigidly connected to and supporting said inner vane carrier;
- said outer vane carrier including an outer support member for engaging and supporting a radially outer flange of one or more of said vanes at a downstream location from said strut structure;
- said inner vane carrier including an inner support member for engaging and supporting a radially inner flange of said one or more vanes;
- and
- wherein said inner vane carrier is supported in cantilevered relation to said outer vane carrier by said plurality of struts.
A support for supporting a vane radially within an inner casing in a turbine engine, the vane located in a hot gas flow from a combustor, on an upstream side, to a turbine section, on a downstream side, the support comprising:
- a framework mounted to the inner casing and including an annular outer vane carrier located radially outwardly adjacent to an upstream end of the inner casing, and an annular inner vane carrier located radially inwardly from the outer vane carrier;
- a strut structure comprising a plurality of circumferentially spaced struts rigidly attached to said outer vane carrier and extending radially inwardly from said outer vane carrier and said strut structure rigidly connected to said inner vane carrier;
- said outer vane carrier including an outer support member for engaging and supporting a radially outer flange of said vane at a downstream location from said strut structure;
- said inner vane carrier including an inner support member for engaging and supporting a radially inner flange of said vane to axially locate said inner flange;
- and
- wherein said inner vane carrier is supported in cantilevered relation to said outer vane carrier by said plurality of struts.
A vane assembly in a turbine engine comprising an inner casing, the vane assembly located within a hot gas flow passing within the inner casing from a combustor, on an upstream side, to a turbine section, on a downstream side, the assembly comprising:
- a framework mounted to and extending radially inwardly from an upstream face of the inner casing and including an annular outer vane carrier located radially outwardly adjacent to the inner casing and an annular inner vane carrier located radially inwardly from said outer vane carrier;
- a strut structure comprising a plurality of circumferentially spaced struts rigidly attached to said outer vane carrier, and said strut structure rigidly connected to said inner vane carrier to support said inner vane carrier in cantilevered relation radially inwardly from said outer vane carrier;
- a plurality of first row turbine vanes supported from said outer vane carrier at a downstream location from said strut structure;
- and
- said inner vane carrier including an inner support member for engaging and supporting said turbine vanes from said inner vane carrier for locating said turbine vanes in an axial direction relative to said inner vane carrier.
