Patent number: 11852029Abstract: An assembly is provided for rotational equipment. This assembly includes a first rotatable body and an injector. The first rotatable body extends axially along and circumferentially about a rotational axis. The first rotatable body includes a first scoop with a first scoop aperture that extends obliquely through the first rotatable body. The injector includes a first nozzle orifice and a second nozzle orifice. The injector is configured to direct a first fluid jet from the first nozzle orifice into an inlet of the first scoop aperture. The injector is further configured to direct a second fluid jet from the second nozzle orifice into the inlet of the first scoop aperture.Type: GrantFiled: August 14, 2020Date of Patent: December 26, 2023Assignee: RTX CORPORATIONInventors: Sin Chien Siw, Charles J. Banas, Timothy Castaldo

Patent number: 11441448Abstract: A rotating seal rotatable about a rotational axis is provided. The rotating seal includes a body having a first surface disposable to face the rotational axis and a second surface disposable to contact with a stationary element. The body defines a cooling channel including one or more entrance channels respectively extending from the first surface, one or more exit channels and a plenum. The plenum extends circumferentially through the body and has a hot side adjacent to the second surface. The plenum is fluidly interposed between the one or more entrance channels and the one or more exit channels whereby fluid exiting the one or more entrance channels and entering the plenum impinges against the hot side.Type: GrantFiled: February 13, 2020Date of Patent: September 13, 2022Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Sin Chien Siw, Timothy Castaldo, Charles Joseph Banas, Jorn Axel Glahn

Patent number: 11193389Abstract: A seal land includes a seal land body that extends circumferentially about an axis and radially between an inner seal land side and an outer seal land side. The seal land body is configured with a plurality of fluid passages arranged about the axis. A first of the fluid passages includes an inner passage segment and an outer passage segment fluidly coupled with the inner passage segment. The inner passage segment extends along a first trajectory within the seal land body towards the outer passage segment. The outer passage segment extends along a second trajectory within the seal land body away from the inner passage segment and towards the outer seal land side. The second trajectory is different than the first trajectory and includes a radial component and a circumferential component.Type: GrantFiled: October 18, 2019Date of Patent: December 7, 2021Assignee: Raytheon Technologies CorporationInventors: Sin Chien Siw, Timothy Castaldo, Charles J.
