Knit fabrics having ceramic strands, thermal protective members formed therefrom and to their methods of construction are disclosed. Methods for fabricating thermal protection using multiple materials which may be concurrently knit are also disclosed. This unique capability to knit high temperature ceramic fibers concurrently with a load-relieving process aid, such as an inorganic or organic material (e.g., metal alloy or polymer), both small diameter wires within the knit as well as large diameter wires which provide structural support and allow for the creation of near net-shape preforms at production level speed. Additionally, ceramic insulation can also be integrated concurrently to provide increased thermal protection.

Flexible seal assemblies having a relatively low torsional rigidity and high longitudinal flexure to thereby allow the flexible seal assembly to flex between adjacent components and maintain a seal, even when movement between adjacent components occurs, is described. In some embodiments, the flexible seal assembly includes one or more layers of metal matrix material, the metal matrix material being comprised of a plurality of short segments of thin wire arranged randomly and sintered together to form a semi-rigid sheet. The one or more layers of metal matrix material can be sandwiched between an upper casing and a lower casing of a metal alloy casing. In various embodiments, additional features are provided for helping to make sure the seal assembly stays together, such as spot welds formed through the seal assembly, an S-shaped casing, and a recess/protrusion feature provided on adjacent layers of metal matrix material.

An object of the present invention is to provide a gasket capable of improving cooling efficiency with a simpler configuration while keeping performance of the gasket and a manufacturing method thereof. A gasket includes a first annular portion which is formed by a metal wire woven fabric obtained by weaving a first metal wire and includes a seal target hole and a main body portion which is in contact with an outer peripheral edge of the first annular portion, in which the first metal wire forming the first annular portion and the first metal wire forming the main body portion are entangled with each other and a second metal wire is woven together with the first metal wire forming the first annular portion to form the first annular portion as a high thermal conduction region.

A seal assembly, comprising a first segment, a second segment, and a seal incorporated between the first segment and the second segment, the seal comprising a mesh. The first segment may comprise a blade outer air seal and the second segment may comprise a vane. In various embodiments, the first segment and the second segment may define a gap, and the seal may seal the gap. The seal may have a first member and a second member that enmeshes the first member. The seal may comprise a member that enmeshes a non-metallic member. The seal may comprise a ceramic fiber enmeshed by a member. The seal may comprise a non-metallic member enmeshed by a metallic member. The seal may comprise a plurality of annular connecting members, each annular connecting member extending about the seal. The seal may comprise a single annular member.

Disclosed is a static seal arrangement for sealing a gap between a first static component and a second static component of a turbomachine such as an aircraft engine or a static gas turbine, having a brush seal held distant from a hot gas, this brush seal being arranged standing or vertical with its clamping section that can be surrounded by cooling air in a radially outer clamping space relative to the gap, and forming a radial sealing site with the first component and an axial sealing site with the second component; also disclosed is a turbomachine.

An assembly can include a turbine housing that includes a bore, a wastegate seat, wastegate passages that extend to the wastegate seat and a divider wall disposed between the wastegate passages where the divider wall includes a divider wall surface; a rotatable wastegate shaft configured for receipt by the bore; a wastegate arm extending from the wastegate shaft; and a wastegate plug extending from the wastegate arm where the wastegate plug includes a contact portion that contacts the wastegate seat to cover the wastegate passages in a closed state and a mesh that contacts the divider wall surface in the closed state.
