A blade for a gas turbine engine includes a fixed length member and a floating blade seal that is movable relative to the floating blade seal to change the length of the blade and vary the gap between the blade and an engine housing component.

A blade outer air seal (BOAS) assembly for an engine case of a gas turbine engine includes a multiple of supported air seal segments and a multiple of floating air seal segments circumferentially alternate with the multiple of supported air seal segments.

A blade outer air seal assembly includes a blade outer air seal that has a plurality of segments that extend circumferentially about an axis and are mounted in a carrier. At least two of the plurality of segments have a first wall and a second wall circumferentially spaced from one another and a base portion that extends from the first wall to the second wall. The base portion extends circumferentially outward past the first and second walls to form first and second sealing surfaces. An intersegment seal has a curved surface. The curved surface is engaged with the first and second sealing surfaces between the at least two segments.

A sealing arrangement includes a stationary component, a first slot is defined between an outer wall and a first inner wall, a second slot is defined between the outer wall and a second inner wall. A rotating component moves in a circumferential direction relative to the stationary component. The rotating component includes a tip rail. A floating seal positioned between the stationary component and the rotating component. The floating seal includes an axial member having a first arm extending into the first slot and a second arm extending into the second slot. The floating seal includes a first radial member and a second radial member that extends from the axial member. A plurality of magnets coupled to the stationary component, the rotating component, and the floating seal. The plurality of magnets is arranged such that the floating seal is contained between the stationary component and the rotating component.

Example apparatus, systems, and articles of manufacture to control deflection mismatch are disclosed herein. Further examples and combinations thereof include: A deflection limiter comprising an inner shroud segment to support a stator structure, the inner shroud segment including a first end face and a first outer upper portion, the first end face positioned radially inward and aft relative to the first outer upper portion, and an outer shroud segment to support the inner shroud segment, the outer shroud segment including a second end face and a second outer upper portion, the second end face positioned aft relative to the first end face and the second outer upper portion positioned aft relative to the first outer upper portion of the inner shroud segment, the second end face coupled to the first end face of the inner shroud segment and the second outer upper portion coupled to the first outer upper portion.

A turbine shroud for use in a gas turbine engine includes a carrier, a blade track segment, and a load-distribution system. The carrier is arranged around a central axis of the turbine shroud. The blade track segment is configured to be supported by the carrier. The load-distribution system is positioned between the carrier and the blade track segment to distribute loads transmitted between the carrier and the blade track segment.

A steam turbine includes a rotary shaft, a blade provided on an outer peripheral surface of the rotary shaft, a casing covering the rotary shaft and the blade from an outer peripheral side, a vane provided on an inner peripheral surface of the casing, and a seal device including a seal ring provided between the outer peripheral surface and the vane and a position adjusting portion configured to adjust a position of the seal ring in a radial direction. A seal clearance adjusting method includes a measurement step of measuring a length of the seal ring in the radial direction from a predetermined reference position as a reference length, a preparation step of preparing an unused seal ring, and an adjustment step of adjusting a length of the unused seal ring from the reference position to be the reference length by the position adjusting portion.
