Patent number: 10508759Abstract: A flowpath assembly has a first conduit defining a flowpath radially inward, and a second conduit spaced radially outward from the first conduit. A void defined between the first and second conduits contains an insulating material that may have a greater porosity than the first and second conduits. The assembly may be additive manufactured generally as one unitary piece with the raw material of the conduits being melted and solidified on a slice-by-slice basis and the insulating material being selectively bypassed by an energy gun of an additive manufacturing system.Type: GrantFiled: July 27, 2017Date of Patent: December 17, 2019Assignee: United Technologies CorporationInventors: Joe Ott, John J.

Patent number: 10488047Abstract: One embodiment includes a fuel injector. The fuel injector assembly comprises a conduit for conveying fuel from a fuel inlet to a nozzle. The conduit is located in a support, with the conduit, the nozzle, and the support being a single unitary piece. A thermally compliant feature is located at the nozzle which allows the fuel injector to adjust for differential thermal expansion.Type: GrantFiled: January 14, 2015Date of Patent: November 26, 2019Assignee: United Technologies CorporationInventors: Joe Ott, Gary A. Schirtzinger, Lexia Kironn, Dennis M. Moura, Stanley J. Funk, Roger O. Coffey

Patent number: 10480868Abstract: A tube assembly that may be for a fuel nozzle of a fuel system of a gas turbine engine may have a first tube defining a first flowpath along a centerline, a second tube generally spaced radially outward from the first tube with a first void located between and defined by the first and second tubes, and a support structure located in the first void and extending between the first and second tubes. The support structure is constructed and arranged to minimize or eliminate thermal conduction between the tubes. The entire assembly may be additive manufactured as one unitary piece. One example of a method of operation may include designed-for breakage of the structural support due to thermal stresses thereby further minimizing thermal conduction between tubes.Type: GrantFiled: February 26, 2018Date of Patent: November 19, 2019Assignee: United Technologies CorporationInventors: Joe Ott, John J.

Patent number: 10208673Abstract: A fluid dispensing apparatus that may be additive manufactured as one unitary piece and may be a fuel injector for a gas turbine engine includes a radial displacement bellows having an outer surface that faces and may be exposed to a surrounding environment and an interior surface that faces and may define at least in-part a flowpath extending along a centerline. The radial displacement bellows is constructed and arranged to move between an expanded state when a pressure differential between the environment and the flowpath is low to a restricted state when the pressure differential is high.Type: GrantFiled: July 2, 2015Date of Patent: February 19, 2019Assignee: United Technologies CorporationInventors: Joe Ott, Stanley J.
