Abstract
A gas turbine engine includes a compressor, a combustor section, and a turbine. The turbine includes an integrated case/stator segment that is comprised of a ceramic matrix composite material.
Claims18
A gas turbine engine comprising:
- a compressor;
- a combustor section;
- and
- a turbine, wherein the turbine includes a first integrated case/stator segment that is comprised of a ceramic matrix composite material, the first integrated case/stator segment comprising:
- a first cylindrical case section that is substantially cylindrical about an axis of the gas turbine engine;
- a first box structure section extending radially inward from the first case section, the first box structure section comprising:
- a first radial support and a second radial support, the first and second radial supports extending radially inward and being axially spaced apart from one another;
- and
- an outer ring that extends between the first and second radial supports and is spaced apart from the case section;
- and
- a first vane airfoil section extending radially inward from the outer ring, wherein the first case section, the first box structure section, and the first vane airfoil section comprise a single integrated component.

An integrated case/stator segment for a gas turbine engine, the integrated case/stator segment comprising:
- a first cylindrical case section that is curved about an axis;
- a first box structure section extending radially inward from the first case section, the first box structure section comprising:
- a first radial support and a second radial support, the first and second radial supports extending radially inward and being axially spaced apart from one another;
- and
- an outer ring that extends between the first and second radial supports and is spaced apart from the case section;
- and
- a first vane airfoil section extending radially inward from the outer ring of the first box structure, wherein the first case section, the first box structure section, and the first vane airfoil section comprise a single integrated component.
4 more elements
An integrated case/stator assembly for a gas turbine engine, the integrated case/stator assembly comprising:
- a first integrated case/stator segment, the first integrated case/stator segment being comprised of a ceramic matrix composite material;
- and
- a second integrated case/stator segment, the second integrated case/stator segment being comprised of a ceramic matrix composite material, wherein the second integrated case/stator segment is attached to the first integrated case/stator segment, and wherein the first and second integrated case/stator segments together form an annulus.
