Patent number: 11518537Abstract: Fuel tank inerting systems are provided. The systems include a fuel tank, an air source arranged to supply air into a reactive flow path, a catalytic reactor having a plurality of sub-reactors along the flow path, and a heat exchanger. The sub-reactors are arranged relative to the heat exchanger such that the flow path passes through at least a portion of the heat exchanger between two sub-reactors along the flow path. At least one fuel injector is arranged relative to at least one sub-reactor. The fuel injector is configured to inject fuel into the flow path at at least one of upstream of and in the respective at least one sub-reactor to generate a fuel-air mixture. A fuel tank ullage supply line fluidly connects the flow path to the fuel tank to supply an inert gas to a ullage of the fuel tank.Type: GrantFiled: June 21, 2018Date of Patent: December 6, 2022Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Sean C. Emerson, Zissis A. Dardas, Robert R. Hebert, Randolph Carlton McGee, Allen Murray, Eric Surawski, Joseph Turney

Patent number: 10967985Abstract: A method for startup of a catalytic oxidation unit includes flowing air from an air source into the catalytic oxidation unit, recycling air from an outlet of the catalytic oxidation unit to an inlet of the catalytic oxidation unit through a recycle duct, and flowing a fuel from a fuel source into the catalytic oxidation to cause a catalytic reaction.Type: GrantFiled: March 14, 2018Date of Patent: April 6, 2021Assignee: Hamilton Sundstrand CorporationInventors: Sean C. Emerson, Zissis A. Dardas, Robert R. Hebert, Allen Murray, Eric Surawski, Randolph Carlton McGee

Patent number: 10801123Abstract: A method of coating a metal article is disclosed that includes immersing a metal article having an exterior anodized layer in a bath containing a chemically active corrosion inhibitor, and applying a voltage to the article during the immersing, the voltage driving the chemically active corrosion inhibitor from the bath into the exterior anodized layer. An article is also disclosed that has a substrate comprising a metal, and a porous anodized layer formed on an exterior surface of the substrate that is infiltrated with a chemically active corrosion inhibitor, the anodized layer having an inward-facing region and an outward-facing region, the anodized layer having a greater concentration of chemically active corrosion inhibitors in the inward-facing region than in the outward-facing region.Type: GrantFiled: March 27, 2017Date of Patent: October 13, 2020Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Zhongfen Ding, Robert R. Hebert, Weilong Zhang, Bart Antonie van Hassel, Mark R. Jaworowski, Michael A. Kryzman, Blair A. Smith, Georgios S. Zafiris, Promila Bhaatia, Mark A. Brege, Shaahin Amini, Vijay V. Pujar
