Abstract: A seal structure may comprise a cavity defined at least partially by an axial surface and a radial surface. A brush seal may be disposed in the cavity. The brush seal may comprise a bristle pack and a backing plate coupled to the bristle pack. A first surface of the backing plate may contact the axial surface, and a second surface of the backing plate may contact the radial surface.

Abstract: The present disclosure relates to advanced materials, particularly single crystal grain structures including the formation of single crystal grain structures. Single crystal grain structures offer improved mechanical properties when used with individual components. Improving mechanical properties is favorable for components that are used in applications with high temperature, pressure, and stress. In these applications, mechanical failure is extremely undesirable. Individual components, such as seals, can be designed with a single crystal grain structure in a preferred direction. By selecting a preferred direction, and orienting the single crystal grain structure accordingly, the single crystal grain structure can improve the component's mechanical properties. Single crystal grain structure seals and the method of forming the seals, therefore, offer various improvements to individual components, specifically when the components are designed for high temperature, pressure, and stress applications.

Abstract: A multi-ply seal ring includes an inner seal ring and an outer seal ring. The inner seal ring includes a plurality of discrete inner ring segments disposed circumferentially about an axis in an annular array. The inner ring segments are arranged end-to-end within the annular array. The inner seal ring is engaged with and nested within the outer seal ring. In addition or alternatively, the outer seal ring may include a plurality of discrete outer ring segments disposed circumferentially about the axis in an annular array.
