  • Publication number: 20250092821
    Abstract: A stator assembly is provided and includes a stator element and a radial height adjustment mechanism. The stator assembly includes an inboard portion which establishes a primary clearance with rotor elements and exhibits a measurable parameter corresponding to the primary clearance and an outboard portion integrally formed with the inboard portion. The radial height adjustment mechanism is coupled with the outboard portion and configured to be operable, based on the measurable parameter, to adjust a radial height of the stator element and in turn to adjust the primary clearance.

  • Patent number: 11814977
    Abstract: A flange arrangement of a gas turbine engine includes a first flange of a first component, and a second flange of a second component axially offset from the first flange along an engine central longitudinal axis. The first flange is secured to the second flange. One or more flange flowpaths are defined between the first flange and the second flange to convey a flange airflow from an interior of the second component thereby thermally conditioning the flange arrangement. The flange airflow is driven through the one or more flange flowpaths by a pressure differential.

  • Patent number: 10141127
    Abstract: A secondary disconnect assembly for use with a circuit breaker moveable between a connected position and a disconnected position includes a first secondary disconnect apparatus and a second secondary disconnect apparatus. The first secondary disconnect apparatus includes a first coupling portion having at least one high speed communications connector. The second secondary disconnect apparatus includes a second coupling portion removably coupled to the first coupling portion. The second coupling portion includes at least one opening configured to receive the high speed communications connector when the circuit breaker is moved from the disconnected position to the connected position to enable high speed data transmission through the first coupling portion and the second coupling portion.
