Patent number: 11493135Abstract: An assembly is provided for rotational equipment. This assembly includes a stationary structure, a rotating structure rotatable about an axial centerline, and a non-contact seal assembly. The non-contact seal assembly is configured to substantially seal a gap between the stationary structure and the rotating structure. The non-contact seal assembly includes a seal shoe configured to sealingly engage the rotating structure axially along the axial centerline.Type: GrantFiled: August 24, 2020Date of Patent: November 8, 2022Assignee: Raytheon Technologies CorporationInventors: Brian F. Hilbert, Mani Sadeghi, Daniel L. Gysling, Kerwin R. Low

Publication number: 20220316598Abstract: An assembly is provided for rotational equipment. This assembly includes a plurality of seal shoes, a seal base and a spring system. The seal shoes are arranged about a centerline in an annular array. The seal shoes include a first seal shoe. The seal base circumscribes the seal shoes. The spring system connects the seal shoes to the seal base. The spring system includes a first spring element and a second spring element. The first spring element extends axially along the centerline in a first axial direction from the seal base to the first seal shoe. The second spring element extends axially along the centerline in a second axial direction from the seal base to the first seal shoe. The second axial direction is opposite the first axial direction.Type: ApplicationFiled: June 13, 2022Publication date: October 6, 2022Inventors: Brian F. Hilbert, Eric A. Grover
