Patent number: 11015715Abstract: A ring seal assembly includes a first seal seat, a second seal seat axially abutting the first seal seat and two or more seal rings located axially between the first seal seat and the second seal seat. One or more pilot features are positioned at one or more of the first seal seat or the second seal seat to radially locate a ring seal of the two or more seal rings during assembly of the ring seal assembly. A method of installing a ring seal assembly includes securing a first seal seat at a rotating component, inserting a first seal ring onto the first seal seat, and installing a second seal ring and a second seal seat to the rotating component. The second seal ring is guided into a selected radial position via one or more pilot features located at the first seal seat and/or the second seal seat.Type: GrantFiled: March 22, 2018Date of Patent: May 25, 2021Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Jonathan Logan Miller, Aneil S. Hegde, Michael M. Davis

Patent number: 10767867Abstract: A bearing support may include a central shaft, a flange shaft, and a tube boss. The central shaft may include a central longitudinal axis extending between a first end and a second end of the bearing support. The flange shaft may extend radially outward of the central shaft at an acute angle, relative to the central longitudinal axis from the first end to the second end, and the flange shaft may include a rim defining an aperture. The tube boss extends from the central shaft radially outward through the aperture, according to various embodiments. An annular channel may be between the rim and the tube boss.Type: GrantFiled: March 21, 2018Date of Patent: September 8, 2020Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Todd A. Davis, Christopher M. Valva, Daniel Rosen, Armando Amador, Aneil S. Hegde, Ramin M. Rafatpanah

Patent number: 10619742Abstract: A ring seal in a gas turbine engine includes a ring seal body, an axial sealing dam, a radial sealing dam, and at least one bleed slot. The ring seal body is annular in shape and has a first axial side, a second axial side, a radially outer side, and a radially inner side. The axial sealing dam is on the first axial side and is configured to provide a first sealing surface with a first component. The radial sealing dam is on the radially outer side and is configured to provide a second sealing surface with a second component radially outward from the radially outer side. The at least one bleed slot is on the second axial side and configured to allow fluid to pass through when the ring seal is incorrectly oriented such that the at least one bleed slot is adjacent to the first component.Type: GrantFiled: July 14, 2017Date of Patent: April 14, 2020Assignee: United Technologies CorporationInventors: Jonathan Logan Miller, Joseph G. Colucci, Colin D. Craig, Aneil S. Hegde, Michael M. Davis
