摘要： A CMC wall (20F) may be attached to a metal wall (22F) by a plurality of bolts (28A, 28B, 28C) passing through respective holes (24A, 24B, 24C) in the CMC wall (20F) and holes in the metal wall (22F), clamping the walls (20F, 22F) together with a force that allows sliding thermal expansion but does not allow vibrational shifting. Distal ones of the holes (24A, 24B) in the CMC wall (20F) or in the metal wall (22F) are elongated toward a central one of the bolts (24C) or at alternate angles to guide differential thermal expansion (20T) of the CMC wall (20F) versus the metal wall (22F) between desired cold and hot geometries. A second CMC wall (20R) may be mounted similarly to a second metal wall (22R) by pins (39A, 39B, 39C) that allow expansion of the CMC component (201) in a direction normal to the walls (20F, 20R).

摘要： A metal vane core or strut (64) is formed integrally with an outer backing plate (40). An inner backing plate (38) is formed separately. A spring (74) with holes (75) is installed in a peripheral spring chamber (76) on the strut. Inner and outer CMC shroud covers (46, 48) are formed, cured, then attached to facing surfaces of the inner and outer backing plates (38, 40). A CMC vane airfoil (22) is formed, cured, and slid over the strut (64). The spring (74) urges continuous contact between the strut (64) and airfoil (66), eliminating vibrations while allowing differential expansion. The inner end (88) of the strut is fastened to the inner backing plate (38). A cooling channel (68) in the strut is connected by holes (69) along the leading edge of the strut to peripheral cooling paths (70, 71) around the strut. Coolant flows through and around the strut, including through the spring holes.

摘要： A configuration of seals disposed around and between a plurality of ring segments (10) arrayed annularly about the periphery of moving blades in a gas turbine engine. The seals function to retain coolant in the plenum (18) within each of the ring segments (10). The seals are disposed atop a substrate (16A), which forms the top of the plenum (18). The first seal (25) is made of a piece of sheet material and seals the gap between adjacent ring segments. This seal has an edge (25A) thereof creased for mating with a similar seal on an adjacent ring segment. A second seal (27), which is also made of sheet material, seals the ends of the plenum (18) of the ring segments (10). Lastly, a third seal (29), which is also made of a piece of sheet material, seals the sides of the second seal (27).

摘要： An apparatus for mounting a refractory component such as a turbine shroud ring segment (32) with a ceramic core (42) onto a combustion turbine engine structure (34). The ring segment has a ceramic matrix composite skin (40), and optionally, a thermal insulation layer (46). A pin (60) is inserted through a bore (48) in the core and through an attachment bar (54) with ends received in wells (50) in the core. The attachment bar may be attached to a backing member, or tophat (64), by a biasing device (76) that urges the refractory component snugly against the backing member to eliminate vibration. The backing member and refractory component have mating surfaces that may include angled sides (52S, 70). The backing member is attached to the engine structure. Turbine shroud ring segments can be attached by this apparatus to a surrounding structure to form a shroud ring.

摘要： An insulated CMC structure (20A) formed of a CMC layer (22A), a thermal insulation layer (24A) applied to a front surface (30A) of the CMC layer (22A), and cooling channels (28A) formed along the interface (26A) between the CMC layer and the thermal insulation layer, thus directly cooling the thermally critical area of the interface. Embodiments include cooling channels in direct contact with both layers (FIG. 1); cooling channels in one layer and tangent to the other layer (FIGS. 4, 5 and 9); cooling channels in the CMC layer with an intervening wall (36D, 36E) that bulges into the thermal insulation layer for improved bonding thereof (FIGS. 6, 7); and cooling channels formed in ceramic tubes (38F of FIG. 8).
