Patent number: 10465701Abstract: A gas turbine engine may have a fan section that includes a variable pitch mechanism for changing the pitch of fan blades. The gas turbine engine may include a fan hub that is rotatable about an engine central longitudinal axis of the gas turbine engine and a blade receiver that is for holding a fan blade and that is rotatably coupled to the fan hub and may be rotatable about a radial axis of the gas turbine engine. The gas turbine engine may include a spring element disposed between the fan hub and the blade receiver to bias the blade receiver radially outward and an annular retaining ring may be disposed around the radial axis and between the fan hub and the blade receiver to limit radially outward movement of the blade receiver to prevent the blade receiver from decoupling and disengaging from the fan hub.Type: GrantFiled: April 21, 2017Date of Patent: November 5, 2019Assignee: UNITED TECHNOLOGIES CORPORATIONInventors: Colin D. Craig, Leslie Charles Kurz

Patent number: 10066774Abstract: A fitting for attaching to double wall tubes includes a body, a fitting center port, an outer seal, a tube connection, a pad connection, an inner seal, a groove, and a diagnostic port. The body has a first surface on a first side of the body and a second surface on a second side of the body. The fitting center port extends through the body for passing a primary fluid flow. The tube connection is on the first side of the fitting, and includes an inner connection and an outer connection. The groove is in the second surface surrounding the inner seal and the groove is configured to receive an outer seal. The diagnostic port is in the second surface for transferring a collected fluid through the body to the outer connection.Type: GrantFiled: March 27, 2015Date of Patent: September 4, 2018Assignee: United Technologies CorporationInventors: Peter S. Matteson, Joseph Martin Gambill, Leslie Charles Kurz, Richard Joseph Bulkovitch, Pawel Socha, Michael Luther Comeau, Usman Khan

Patent number: 9926851Abstract: A spring assembly has a spring end for engagement with a component to bias the component in a first direction. The spring end is connected to a plurality of coils, which have an inner peripheral surface, and are mounted about a pivot pin. A damper is positioned between an outer peripheral surface on the pivot pin and the inner peripheral surface of the spring coils. The damper is engaged by the spring coils, if the spring end is driven in a direction opposed to the first direction. A one-way drive assembly and a gas turbine engine are also disclosed.Type: GrantFiled: March 5, 2015Date of Patent: March 27, 2018Assignee: United Technologies CorporationInventors: Christopher T. Anglin, Leslie Charles Kurz

Patent number: 9359912Abstract: A runner assembly for a circumferential seal assembly includes a runner defined about an axis. The runner has an inwardly extending runner mounting flange. A radially flexible clamp is engaged with the inwardly extending mounting flange. An axial spring is trapped between an axial retainer and the runner. The runner, the radially flexible clamp, the axial spring, and the axial retainer are co-rotatable about the axis. The axial retainer is radially inline with the runner and spaced from a radially inner surface of the runner such that there is a radial gap between the axial retainer and the radially inner surface of the runner permitting radial movement of the runner.Type: GrantFiled: January 10, 2011Date of Patent: June 7, 2016Assignee: United Technologies CorporationInventors: M. Rifat Ullah, Jonathan Logan Miller, Leslie Charles Kurz

Publication number: 20160061202Abstract: A pump assembly includes a housing having a first lobe. A shaft rotates at least partially inside the housing about an axis and has an outer surface. A base member is mounted on the shaft so as to rotate with the shaft. The base member is mounted on a location of the shaft such that at least a portion of the base member is located within the first lobe. A fin protrudes generally axially from the base member. The fin is configured to extend outward from the outer surface of the shaft.Type: ApplicationFiled: August 20, 2015Publication date: March 3, 2016Inventors: Hung Duong, Leslie Charles Kurz
