Patent number: 11021985Abstract: A seal device includes a plurality of seal shoes, a seal base, a plurality of spring elements and a resilient biasing element. The seal shoes are arranged around an axis. The seal base circumscribes the seal shoes. Each of the spring elements is radially between and connects a respective one of the seal shoes and 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 a first of the seal shoes. The second mount is connected to the seal base. The spring beam connects the first mount to the second mount. The resilient biasing element is radially between and engaged with first and second components of the seal device, where the first component is configured as or otherwise includes the first mount or the second mount.Type: GrantFiled: January 14, 2019Date of Patent: June 1, 2021Assignee: Raytheon Technologies CorporationInventor: Tara L. D'Ambruoso

Patent number: 10830081Abstract: 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.Type: GrantFiled: July 17, 2017Date of Patent: November 10, 2020Assignee: Raytheon Technologies CorporationInventors: Conway Chuong, Tara L. D'Ambruoso, Dwayne K. Mecklenburg, Peter E. Gunderson, Eric D. Gray

Patent number: 10822983Abstract: A hydrostatic seal assembly includes a seal support, a seal shoe integral to the seal support and radially movable relative to the seal support. A plurality of seal teeth are located at a radially inboard surface of the seal shoe. The seal shoe is formed from a first material and the radially inboard surface is formed from a second material softer than the first material such that the radially inboard surface is abradable in the event of a rub between the radially inboard surface and an adjacent rotating component.Type: GrantFiled: February 6, 2018Date of Patent: November 3, 2020Assignee: RAYTHEON TECHNOLOGIES CORPORTATIONInventors: Michael L. DiFrancesco, Tara L. D'Ambruoso
