摘要： An apparatus for a gas turbine engine, such as a transition (225, 325), includes a metal shell (200, 300) surrounding a body (230, 330) that is comprised of a ceramic matrix composite (CMC)-comprising structure (231) and a ceramic insulating layer (265) bonded thereto. The metal shell (200, 300) defines a space (250) adapted to contain the transition body (230, 330), and comprises at least one protrusion (220) adapted to contact the transition body (230, 330). A pin (255) passes through the transition body (230, 330) and the metal shell (200, 300) at their forward ends, and a compliant porous element (240) is adapted to fit in the space (250) between the metal shell (200, 300) and the transition body (230, 330). A preload spring (260, 360) is provided in an urging orientation with the transition body (230, 330) wherein the preload spring (260, 360) is positioned against a first region (333) of the transition body and is adapted to urge the transition body toward one of the at least one protrusion (220), positioned against a second region (335) generally opposite the first region, and also to preload the compliant porous element (240). One or more of the at least one protrusion (220) in an embodiment may be a hard stop, and in some embodiments in the preload at least one of these may be loaded.

摘要： A ceramic ring segment for a turbine engine that may be used as a replacement for one or more metal components. The ceramic ring segment may be formed from a plurality of ceramic plates, such as ceramic matrix composite plates, that are joined together using a strengthening mechanism to reinforce the ceramic plates while permitting the resulting ceramic article to be used as a replacement for components for turbine systems that are typically metal, thereby taking advantage of the properties provided by ceramic materials. The strengthening mechanism may include a ceramic matrix composite overwrap or plurality of overwraps designed to help prevent delamination of the ceramic plates when the ceramic article is in use by placing the plates in compression.

摘要： Aspects of the invention are directed to a ceramic matrix composite ring seal segment. The ring seal segment according to aspects of the invention includes a relatively simple body that is circumferentially curved. At least a portion of the hot gas path surface of the ring seal segment can be coated with a thermal insulating. material. In one embodiment, each ring seal segment can be operatively connected to a stationary support structure, such as by way of isolation rings. The ring seal segments and/or the isolation rings can be configured so as to restrain the ring seal segments in the axial, radial and/or circumferential directions. The ring seal segments can be attached to the isolation rings so that the support points act opposite the operating pressure loads. Thus, the ring seal segments carry these loads in compression, a strong direction of the CMC fibers.

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).
