Patent number: 11752580Abstract: A system is for bonding a cover sheet to a core to form or repair a dual wall structure. The system includes a cover sheet probe and an inner pedestal probe. A three dimensional contoured tip of the cover sheet probe abuts against a three dimensional contoured outer surface of the cover sheet opposite a pedestal of the core. The pedestal abuts the inner surface of the cover sheet. The inner pedestal probe may be coupled to the core to create a conductive electrical path from the cover sheet probe through at least part of the structure. A flow of electric power is controlled and supplied to the cover sheet probe to heat a junction between the area of the cover sheet abutting the pedestal and the pedestal. A heated area is created in the junction and fixedly couples the coversheet and the pedestal.Type: GrantFiled: June 29, 2022Date of Patent: September 12, 2023Assignee: ROLLS-ROYCE CORPORATIONInventors: Joseph P. Henderkott, Timothy Fuesting, Raymond Xu

Patent number: 11717907Abstract: A bonding probe is used for bonding a cover sheet to a core to form or repair a dual wall structure. The bonding probe includes a body, an attachment end at a distal end of the body, a head at an opposite end of the body, a tip extending from the head, and a cooling passageway. The attachment end couples the body to a resistance welder. The tip extends to form a proximate end of the body. The tip includes a contacting area having a predetermined three dimensional contoured surface. The contacting area aligns with a predetermined area of a three dimensional outer surface of a cover sheet of a dual walled structure. The cooling passageway provides a passageway for a flow of cooling fluid. The cooling passageway extends through the head, and into the tip.Type: GrantFiled: May 8, 2020Date of Patent: August 8, 2023Assignee: ROLLS-ROYCE CORPORATIONInventors: Joseph P. Henderkott, Timothy Fuesting, Raymond Xu

Patent number: 11571762Abstract: A printing method for selectively depositing braze powders on a surface comprises extruding a filament from a nozzle moving relative to a surface, where the filament comprises a flowable carrier mixed with a braze powder. As the nozzle moves, the filament is deposited on the surface in a predetermined pattern defined by the motion of the nozzle relative to the surface; thus, the braze powders are deposited at one or more predetermined locations on the surface.Type: GrantFiled: November 15, 2019Date of Patent: February 7, 2023Assignees: Rolls-Royce North American Technologies Inc., ROLLS-ROYCE CORPORATIONInventors: Matthew Gold, Greg Lopshire, Raymond Xu, Carl Russo
