Patent number: 12044488Abstract: A method of manufacturing a heat exchanger. The method includes additively manufacturing a first body with a first plurality of passages extending through the first body. Additively manufacturing a second body with a second plurality of passages extending through the second body. The method also includes, interlocking the first body with the second body such that the first plurality of passages is aligned with the second plurality of passages and fluidically connected with the second plurality of passages.Type: GrantFiled: October 1, 2021Date of Patent: July 23, 2024Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Callie Benson, Daniel E. Muntges, John Sypek, Keith J. Brooky, Paul M. Colson, Michael Doe

Patent number: 10495231Abstract: A disclosed method of hard coating a wear surface of a valve of an aircraft air management system is performed by depositing a hardface alloy powder onto the wear surface, heating the wear surface and the hardface alloy powder to transform the hardface alloy powder into a molten liquid mass, and subsequently cooling the molten liquid hardface alloy mass to solidify the hardface alloy onto the wear surface. The disclosed process provides for localized application and subsequent bonding of the hardface alloy to discrete portions of the wear surface. The solidified hardface alloy coating may then be machined to obtain specific wear surface geometries.Type: GrantFiled: June 17, 2016Date of Patent: December 3, 2019Assignee: Hamilton Sundstrand CorporationInventors: Kevin M. Rankin, Blair A. Smith, Timothy R. Boysen, Aaron T. Nardi, Keith J. Brooky

Publication number: 20170343113Abstract: A thrust plate for a butterfly valve includes a thrust plate body that defines a recess that extends between a bottom thrust surface, side walls, and an open top. There is a nickel-based or cobalt-based wear-resistant coating located on the bottom thrust surface. The wear-resistant coating is harder than the thrust plate body.Type: ApplicationFiled: August 16, 2017Publication date: November 30, 2017Inventors: Peter J. Dowd, John M. Dehais, Blair A. Smith, Timothy R. Boysen, Keith J. Brooky, Aaron T. Nardi, Kevin M. Rankin

Patent number: 8763988Abstract: A butterfly valve comprises a housing including a bore, a rotatable shaft passing through the bore, a disc mounted to the shaft for controlling the flow of a fluid through the bore, a thrust load reacting section and a wear interface. The thrust load reacting section includes a thrust plug assembled in a thrust reacting end of the shaft and a thrust plate secured to the housing. The thrust plate has a well for axially retaining the thrust plug and the thrust reacting end of the shaft. The wear interface includes a first contact region on the thrust plug with a first contact surface and a second contact region at the base of the well with a second contact surface. A portion of the first contact surface is spherical and in contact with a portion of the second contact surface.Type: GrantFiled: January 17, 2011Date of Patent: July 1, 2014Assignee: Hamilton Sundstrand CorporationInventors: Peter J. Dowd, John M. Dehais, Blair A. Smith, Kevin M. Rankin, Timothy R. Boysen, Keith J. Brooky, Aaron T. Nardi
