Abstract
A turbine engine includes a diffuser connecting a compressor section and a turbine section. The diffuser includes a diffuser frame and multiple diffuser case sections are connected to the diffuser frame.
Claims16
A turbine engine comprising:
- a diffuser connecting a compressor section and a turbine section;
- the diffuser comprising a diffuser frame having a first ring, a second ring, and a plurality of structural ribs connecting said first ring and said second ring, and at least one structural mount structurally connecting the diffuser frame to an engine support, the diffuser further comprising a plurality of diffuser case sections connected to, and protruding radially outward from, said plurality of structural ribs;
- at least one combustor case extending radially outward from at least one of said plurality of diffuser case sections;
- and
- wherein each of said plurality of structural ribs comprises at least one flange portion, and wherein said at least one flange portion is radially thinner than a remainder of said each of the plurality of structural ribs and extends a full axial length of said each of the plurality of structural ribs, relative to an axis defined by the gas turbine engine, and each of said plurality of diffuser case sections is connected to the at least one flange portion along at least a portion of the full axial length of a corresponding structural rib of said plurality of structural ribs.
2 more elements
A method for maintaining a turbine engine comprising:
- removing a diffuser case section while said turbine engine is in situ, by disconnecting at least a portion of the diffuser case section from at least one flange portion of a structural rib, the flange portion extending a full axial length of the structural rib, the diffuser case section being connected to the at least one flange portion along at least a portion of the full axial length of the structural rib;
- accessing a component;
- servicing said component;
- and
- replacing said diffuser case section.

A land based turbine engine comprising:
- a compressor section;
- a combustor section fluidly connected to the compressor section;
- a turbine section fluidly connected to the combustor section;
- a diffuser disposed in said combustor section,
- the diffuser comprising a diffuser frame having a first ring, a second ring, and a plurality of structural ribs connecting said first ring and said second ring, and at least one structural mount structurally connecting the diffuser frame to an engine support, the diffuser further comprising a plurality of diffuser case sections connected to, and protruding radially outward from, said plurality of structural ribs;
- at least one combustor case extending radially outward from at least one diffuser case section of the plurality of diffuser case sections;
- and
- wherein each of said plurality of structural ribs comprises at least one flange portion, and wherein said at least one flange portion is radially thinner than a remainder of said each of the plurality of structural ribs and extends a full axial length of said each of the plurality of structural ribs, relative to an axis defined by the gas turbine engine, and each of said plurality of diffuser case sections is connected to the at least one flange portion along at least a portion of the full axial length of a corresponding structural rib of said plurality of structural ribs.
