1. 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; andan outer ring that extends between the first and second radial supports and is spaced apart from the case section; anda 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.
