Patent number: 9500099Abstract: A component for a gas turbine engine according to an exemplary embodiment of the present disclosure includes, among other possible things, a platform having a non-gas path side and a gas path side, an airfoil extending from the gas path side of the platform, and a cover plate positioned adjacent to the non-gas path side of the platform. The cover plate can include a first plurality of openings that communicate a first portion of a cooling air to a first cooling cavity of the platform and a second plurality of openings that can communicate a second portion of the cooling air to the second cooling cavity that is separate from the first cooling cavity. Each of the first cooling cavity and the second cooling cavity can include a plurality of augmentation features.Type: GrantFiled: July 2, 2012Date of Patent: November 22, 2016Assignee: UNITED TECHOLOGIES CORPORATIONInventors: Brandon W. Spangler, Russell J. Bergman

Patent number: 9464350Abstract: An apparatus for depositing a coating on one or more parts (21) has: a chamber (22); a part holder (64) for carrying the part(s); a bias voltage source (94) coupled to the part(s) to apply a bias voltage to the part(s); a source (34) of the coating material; a plurality of temperature sensors (76); and a plurality of leads (90) passing outputs of the temperature sensors out from the chamber. A temperature monitoring system (150) has a temperature data processor (300). At least one fiber optic link (223) couples the temperature data processor to the temperature sensors so as to electrically isolate the temperature data processor from the bias voltage.Type: GrantFiled: March 17, 2014Date of Patent: October 11, 2016Assignee: United Techologies CorporationInventors: Richard S. Mullin, Anatoly Kuzmichev, Igor V. Belousov, Yuriy G. Kononenko, Oleg G. Pankov, Dmitriy Ryzhikov

Publication number: 20140174409Abstract: A fuel system is disclosed. The fuel system may include a fuel supply, a fuel supply conduit fluidly connecting the fuel supply to an engine, and a fuel pump in fluid communication with the fuel supply conduit. The fuel system may also include a bypass conduit including a first end fluidly connected to the fuel supply conduit proximate an inlet of the fuel pump, and a second end fluidly connected to the fuel supply conduit proximate an outlet of the fuel pump. The fuel system may also include a bypass valve in fluid communication with the bypass conduit. The bypass valve may be configured to allow fuel to flow from the first end to the second end of the bypass conduit.Type: ApplicationFiled: December 21, 2012Publication date: June 26, 2014Applicant: United Techologies CorporationInventor: David Lloyd Ripley
