摘要： Aspects of the disclosure are directed to an engine comprising: a first structure, a second structure configured to rotate relative to the first structure, and a floating, non-contact seal that interfaces the first structure and the second structure, where the seal includes: a shoe, a first beam coupled to the shoe, and a second beam coupled to the shoe, where during a non-operational state of the engine a reference point of the shoe is substantially centered within a range of radial deflections of the reference point of the shoe over the operating range of the engine.

摘要： A non-contact seal assembly is provided. The non-contact seal assembly includes a plurality of seal shoes 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. The non-contact seal assembly may comprise a seal base circumscribing the annular array of the seal shoes. The non-contact seal assembly may further comprise a plurality of spring elements, each of the spring elements radially between and connecting a respective one of the seal shoes with the seal base, where the plurality of seal shoes each includes a weight reduction pocket formed in a circumferential region of the seal shoe.

摘要： A rotor assembly for a gas turbine engine includes a rotor disc having an axially extending rotor disc arm and a plurality of rotor blades extending radially outwardly from the rotor disc. A cover plate is located at an axial face of the rotor disc and at least partially retained at a rotor disc arm. The rotor disc and cover plate define a rotor cavity. A plurality of airflow openings extend into the cavity to allow a flow of air into the rotor cavity to thermally condition the rotor disc and the cover plate at the rotor cavity.

摘要： A non-contact seal assembly includes a plurality of seal shoes 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. A seal base circumscribes the annular array of the seal shoes. The assembly also includes a plurality of spring elements, each of the spring elements radially between and connecting a respective one of the seal shoes with the seal base. Each of the spring elements comprises a first beam having a first beam thickness and a second beam thickness, where the first and second beam thicknesses are different.

摘要： A retaining ring for a turbomachine disk and coverplate assembly includes a ring body defining a coverplate interface side and an opposed disk lip interface side. A flow feature is defined by the ring body on the coverplate interface side to allow airflow between the turbomachine disk coverplate and the ring body such that a pocket defined between the coverplate and the turbomachine disk is in fluid communication with a conditioning flow pathway through the retaining ring.

摘要： An assembly includes a plurality of seal shoes, a seal base and a plurality of spring elements. The seal shoes are arranged around an axis in an annular array. 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 to the seal base. A first of the spring elements includes a first mount, a second mount and a spring beam. The first mount is connected to the first seal shoe. The second mount is connected to the seal base and disposed a circumferential distance away from the first mount. The spring beam extends longitudinally along a non-straight centerline between and connected to the first mount and the second mount.
