Patent number: 10227896Abstract: Systems and methods for suppressing infrared radiation generated by a turbine engine. A system comprises a primary assembly having a center body, a plurality of vanes extending from the center body, an outer radial duct with the plurality of vanes extending therethrough, a structural baffle, and a mixer. The primary assembly is disposed in the exhaust flow path of a turbine engine and encased in ducting and/or an airfoil. An air flow path defined between the center body and outer radial duct is axially spit by an interface rim and flow segregator. The flow segregator segregates engine core flow from ambient air flow.Type: GrantFiled: March 17, 2016Date of Patent: March 12, 2019Assignees: ROLLS-ROYCE CORPORATION, ROLLS-ROYCE NORTH AMERICAN TECHNOLOGIES INC.Inventors: James C. Muskat, Todd S. Taylor, Mike Nesteroff, Eric Donovan, James Carl Loebig

Patent number: 9752607Abstract: A retention pin assembly may include a stud having a head, a shaft, and a deformable end. The shaft may include a stepped surface having a greater diameter than the deformable end. The assembly may include a support member having an opening for receiving the deformable end. The support member may include a pocket. The stepped surface of the shaft may position the stud in relation to the support member. The deformable end of the stud may be operable to be melted to form a mechanical retainer within the pocket without forming a metallurgical joint between the stud and the pocket.Type: GrantFiled: March 11, 2014Date of Patent: September 5, 2017Assignee: Rolls-Royce North American Technologies, Inc.Inventor: James C. Muskat

Patent number: 9028188Abstract: An improved retention pin assembly and method of forming a pin assembly that uses a melt in a pocket without a metallurgical joint having been formed. The assembly can be generated by a method of forming a joint which includes providing a metal shaft and a member that is operable to receive the shaft. A pocket is formed within the member which operates to receive a melt pool. Next the shaft is inserted into apertures in the member. A welding or melting operation is then performed to create a melted portion that occupies the pocket. A joint is created using a retention pin.Type: GrantFiled: December 10, 2013Date of Patent: May 12, 2015Assignee: Rolls-Royce North American Technologies, Inc.Inventor: James C. Muskat

Patent number: 6164917Abstract: A lightweight high temperature multiproperty rotor disk and method of manufacture for use in a gas turbine engine. The rotor disk of a nickel super alloy and having a plurality of lightweight high temperature single crystal blade attachment lugs bonded thereto. The single crystal high temperature rotor blade attachment lugs being cast in a substantially rectangular shape and bonded to the circumference of the disk. A method of manufacturing the rotor includes positioning the plurality of single crystal attachment lugs on a positioning ring that has locating nests formed thereon. Subsequently, the rotor disk is placed within the bonding ring and a restraining ring is placed around the entire subassembly. Upon subjecting the assembly to high temperature the rotor disk, having a coefficient of thermal expansion greater than the coefficient of thermal expansion of the restraining member, forces the components into a mating relationship.Type: GrantFiled: April 6, 1998Date of Patent: December 26, 2000Assignee: Allison Engine Company, Inc.Inventors: Christine M. Frasier, James C. Muskat, Charles J. Teague
