摘要： A method for making a ceramic matrix composite component includes densifying a fibrous preform of the component with a ceramic matrix to form an intermediate component; infiltrating a hole in the intermediate component with an infiltrate material comprising a solid and a metallic alloy whose reaction forms a carbide, silicide, boride or combination thereof, heating the infiltrate material to a temperature in excess of a melting point of the metallic alloy; and sequentially cooling regions of the hole starting from an interior end of the hole to the outer surface of the intermediate component to form a solidified through-thickness reinforcement element. The hole extends in a through-thickness direction and is open to an exterior surface of the intermediate component.

摘要： A turbine, and particularly a low pressure turbine is disclosed, which comprises a plurality of rotor members and spacers for arranged between rotor members, to avoid that an ingested gas flow from the hot gas flow path channel reaches the wheel space. The rotor members each include a deflector. The deflector is placed in correspondence with each spacer and deflects the purging air pumped up from the wheel spaces by the rotor members, to prevent the ingested gas flow to heat up the roots of the blades.

摘要： A sealing system for sealing between components. The sealing system includes a first component, a second component, and a seal assembly including a seal member. The first component includes a first component surface, and the second component includes a second component surface. The second component surface is oriented in a direction transverse to the first contact surface. The seal member has a plurality of contact surfaces including a first contact surface and a second contact surface. The first contact surface is configured to contact the first component surface and to slide relative to the first component surface. The second contact surface is configured to contact the second component surface and to slide relative to the second component surface. The second contact surface is oriented in a direction transverse to the first contact surface.

摘要： An assembly is provided for a gas turbine engine. This gas turbine engine assembly includes a seal carrier, a seal land, a seal ring, a plate and a fastener. The seal carrier has an annular groove and extends between a first side and a second side. The seal land is opposite the annular groove. The seal ring seals a gap between the seal carrier and the seal land. The seal ring is seated in the annular groove. The plate is at the second side of the seal carrier. The fastener includes a head and an elongated member connected to the head. The head is at the first side of the seal carrier. The elongated member projects out from the head through the seal carrier, the seal ring and the plate. The elongated member is bonded to the plate.

摘要： Proposed is a turbine vane platform sealing assembly in which compressed air is prevented from leaking to a turbine vane to improve power generation efficiency. The turbine vane platform sealing assembly includes a first sealing member inserted into a first groove formed in a turbine vane platform in a first direction, the first sealing member extending in the first direction, a second sealing member inserted into a second groove formed in a second direction intersecting the first direction of the turbine vane platform, with an end part of the second sealing member being in contact with an upper surface of the first sealing member, and the third sealing member having a portion formed by extending in the first direction and a remaining portion formed by bending in the second direction at a bend line at which the first sealing member and the second sealing member contact.

摘要： A flow path component assembly includes a flow path component that has a platform that extends from a first circumferential side to a second circumferential side. The platform has a first radius of curvature between the first circumferential side and the second circumferential side. A coating is arranged on a portion of the platform near the first circumferential side. The coating has a second radius of curvature. The second radius of curvature is larger than the first radius of curvature.
