Classification: CPC F | IPC F

Claim 0:
1. A nozzle segment assembly for a gas turbine engine, the nozzle segment assembly comprising an inner hanger, an outer hanger, and an airfoil assembly, the airfoil assembly comprising:
an outer band comprising a radially-outward facing surface;
an inner band comprising a radially-inward facing surface;
at least one airfoil body extending between the outer band and the inner band, the at least one airfoil body comprising:
an outer end extending through the outer band and protruding outward from the radially-outward facing surface of the outer band; and
an inner end extending through the inner band and protruding radially inward from the radially-inward facing surface of the inner band;

wherein:
the outer hanger is disposed radially outward from the outer band and the outer end of the at least one airfoil body;
an inwardly facing surface of the outer hanger faces radially inward towards the outer end of the at least one airfoil body;
the inner hanger is disposed radially inward from the inner band and the inner end of the at least one airfoil body;
an outwardly facing surface of the inner hanger faces radially outward towards the inner end of the at least one airfoil body;
the outer end of the at least one airfoil body engages with the outer hanger and the inner end of the at least one airfoil body engages with the inner hanger to position and constrain the airfoil assembly;
the inner hanger, the outer hanger, or both comprise at least one axial mount comprising an axial engagement surface that is planar, wherein each axial mount and the axial engagement surface thereof extends either radially inward from the inwardly facing surface of the outer hanger or radially outward from an outwardly facing surface of the inner hanger;
the axial engagement surface is in contact with only a portion of an exterior surface or an interior surface of the at least one airfoil body; and
the outer band, the inner band, and the at least one airfoil body comprise a ceramic matrix composite (CMC) material.
