Patent number: 11459904Abstract: A seal assembly for a gas turbine engine includes first and second split-ring seals. The first split-ring seal includes circumferentially separated first and second ends, laterally separated first and second edges, a first sealing lobe adjacent the first edge, and a first integral clip portion adjacent the second edge. The first sealing lobe has a curved surface extending laterally outward from the first edge. The second split-ring seal is slidably received and nested in the first seal. The second split-ring seal includes circumferentially separated third and fourth ends and laterally separated third and fourth edges.Type: GrantFiled: June 26, 2019Date of Patent: October 4, 2022Assignee: Raytheon Technologies CorporationInventors: Jeffrey D. Ponchak, Frederick M. Schwarz, David L. Motto

Patent number: 11428241Abstract: An improved stator assembly is disclosed. The stator assembly may comprise an exit guide vane, an OD ring, and an ID ring. The exit guide vane may couple at one end to the OD ring and at an opposite end to the ID ring. The exit guide vane may comprise a leading edge opposite of a trailing edge. The OD ring and the ID ring may couple to a diffuser assembly of a gas turbine engine. The stator assembly may further comprise an aft OD seal, a forward OD seal, an ID seal, and a diffuser assembly seal to reduce airflow leaks around the stator assembly.Type: GrantFiled: April 22, 2016Date of Patent: August 30, 2022Assignee: Raytheon Technologies CorporationInventors: Frederick M. Schwarz, Jeffrey D. Ponchak

Patent number: 11125092Abstract: A gas turbine engine includes a case assembly and a stator segment. The case assembly defines a first slot having a first surface and a second surface. The stator segment includes a shroud body axially extends between a first body end and a second body end. A first flange extends into the first slot. The first flange has a first flange first side, a first flange second side, a first flange first surface and a first flange second surface each circumferentially extending between the first flange first side and the first flange second side. A first portion of the first flange first surface engages the first surface. A second portion of the first flange first surface. A third portion of the first flange first surface is spaced apart from the first surface.Type: GrantFiled: August 14, 2018Date of Patent: September 21, 2021Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Jeffrey D. Ponchak, Alex Daniel Morrow, Charles H. Warner
