摘要： Aspects of the disclosure are directed to a seal comprising: a shoe, and at least two beams coupled to the shoe, where a first width associated with the beams exceeds a second width associated with the shoe in a reference direction. Aspects of the disclosure are directed to an engine comprising: a compressor section, a turbine section, and a floating, non-contact seal that includes: a shoe, and at least two beams coupled to the shoe, where the beams extend past an edge of a flowpath surface associated with the shoe in a reference direction.

摘要： A non-contact seal assembly is provided. This assembly includes a plurality of seal shoes, a seal base and a plurality of spring elements. The seal shoes are arranged about a centerline in an annular array. The seal shoes include a first seal shoe extending axially along the centerline between a first shoe end and a second shoe end. An aperture may extend partially axially into the first seal shoe from the first shoe end and laterally within the first seal shoe. The seal base circumscribes the annular array of the seal shoes. Each of the spring elements is radially between and connects a respective one of the seal shoes with the seal base.

摘要： An assembly is provided for rotational equipment with an axial centerline. This assembly includes a primary seal device, a ring structure and a secondary seal device. The primary seal device is configured as a hydrostatic non-contact seal device. The primary seal device includes a plurality of seal shoes and a seal base. The seal shoes are arranged circumferentially about the axial centerline in an annular array. The seal base circumscribes the annular array of the seal shoes. The ring structure is axially engaged with the seal base. The secondary seal device is mounted with the ring structure. The secondary seal device includes a seal ring body and an alignment tab. The seal ring body is configured to substantially seal an annular gap between the ring structure and the seal base. The alignment tab projects out from the seal ring body and into an aperture in the ring structure. The alignment tab is adapted to substantially rotationally locate and/or fix the secondary seal device to the ring structure.

摘要： A method of forming an airfoil, includes forming a hybrid skin core, a tip flag core, and a trailing edge core. The hybrid skin core, tip flag core, and trailing edge core are connected to form a first core portion. A leading edge core and a serpentine core are formed. The first core portion, the leading edge core, and the serpentine core are assembled together to form an airfoil core. An airfoil is formed around the airfoil core.

摘要： A seal assembly includes an annular base, a spring, a shoe, a first channel, a seal cover, and a seal. The spring includes a beam and is connected to the annular base. The shoe is disposed radially inward of the annular base and connected to the spring. The shoe includes an upstream portion, a downstream portion, and a lip connected to and extending radially outward from the upstream portion of the shoe. The spring extends from the annular base to the shoe. The first channel is positioned between the shoe and the beam of the spring. The seal is disposed between the seal cover and the shoe such that a downstream face of the seal is in contact with an upstream face of the shoe.
