Patent number: 11970586Abstract: A composite material may be prepared from a solid polymeric binder and a solid filler by feeding into an extruder the solid polymeric binder at a first feed rate and the solid filler at a second feed rate. The extruder extrudes an extrudate of the solid polymeric binder and solid filler to form the composite material. The composite material has a binder to filler ratio determined by the first feed rate and second feed rate. The solid polymeric binder and solid filler have different densities. Feeding the solid polymeric binder at the first feed rate and the solid filler at the second feed rate distributes the solid filler substantially homogeneously throughout the composite material.Type: GrantFiled: June 8, 2023Date of Patent: April 30, 2024Assignees: FLORIDA LEAGUE OF CITIES, INCORPORATED, United States of America As Represented By The Administrator of NASAInventors: Salih Kocak, Christopher L. Holley, II, Nathan Gelino, Tracy Gibson, James Captain, Robert P. Mueller

Publication number: 20190309794Abstract: A thrust bearing assembly for a machine includes a stator housing, a fluid film thrust bearing, and a ring bearing. The stator housing surrounds at least a segment of a rotor shaft and one or more runners on the rotor shaft that include a first runner surface and a second runner surface facing in opposite axial directions along the rotor shaft. The fluid film thrust bearing is axially held between a first stator surface of the stator housing and the first runner surface. The fluid film thrust bearing is configured to generate a fluid cushion that blocks the first runner surface from engaging the fluid film thrust bearing. The ring bearing is axially held between a second stator surface of the stator housing and the second runner surface. The ring bearing has an annular contact surface that engages the second runner surface to axially support the rotor shaft.Type: ApplicationFiled: April 4, 2018Publication date: October 10, 2019Inventors: Christopher Edward Wolfe, Adolfo Delgado, Nathan Gibson, Deepak Trivedi, Bugra Ertas

Patent number: 9033657Abstract: Embodiments of a gas turbine engine including a lift-off finger seal are provided, as are embodiments of a lift-off finger seal and embodiments of a method for the manufacture thereof. In one embodiment, the gas turbine engine includes an engine housing having low and high pressure cavities, a shaft rotatably mounted in the engine housing, and a lift-off finger seal. The lift-off finger seal includes an finger seal backing spring and an aerodynamic foil. The aerodynamic foil extends around the outer circumference of the shaft and is configured to expand radially outward in response to aerodynamic forces generated during rotation of the shaft. The finger seal backing spring resiliently biases the aerodynamic foil toward the shaft, deflects to accommodate the outward radial expansion of the aerodynamic foil, and forms an annular seal around the aerodynamic foil to impede pressurized airflow from the high to low pressure zone.Type: GrantFiled: December 12, 2011Date of Patent: May 19, 2015Assignee: HONEYWELL INTERNATIONAL INC.Inventor: Nathan Gibson

Patent number: 8230835Abstract: Emergency lubrication systems and methods for an engine are provided. One system includes a primary lubrication system including a de-aeration oil tank configured to store de-aerated oil until the oil is de-aerated, a first oil supply line configured to provide de-aerated oil to the engine, and a first valve configured to control the flow of oil through the primary lubrication system. The system further includes a secondary lubrication system including a second valve coupled to the de-aeration oil tank and configured to control the flow of oil through the secondary lubrication system, and a second oil supply line coupled to the engine and to the de-aeration oil tank via the second valve. One method includes the steps of detecting a predetermined event in the engine, preventing the aerated oil from entering the primary lubrication system, and using the aerated oil in the secondary lubrication system to lubricate the engine.Type: GrantFiled: March 10, 2009Date of Patent: July 31, 2012Assignee: Honeywell International Inc.Inventors: Nathan Gibson, John Hogan, John D.

Publication number: 20120033904Abstract: A hydrodynamic gas film bearing cooling gas control system includes a hydrodynamic gas film bearing, a supply conduit, and a flow control device. The supply conduit is in fluid communication with the hydrodynamic gas film bearing, is coupled to receive a flow of cooling gas from a cooling gas supply source, and is configured to supply the flow of cooling gas to the hydrodynamic gas film bearing. The flow control device is coupled to the supply conduit and is responsive to a physical characteristic of the cooling gas or ambient environment to move between at least two positions to thereby vary the flow of cooling gas, through the supply conduit, to the hydrodynamic gas film bearing.Type: ApplicationFiled: August 5, 2010Publication date: February 9, 2012Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Nathan Gibson, Don Takeuchi, Walter Lee Meacham, James Knorr
