Patent number: 11946549Abstract: A fuel nozzle metering valve that includes a spool having an inlet port and an outlet flow port, and a retainer assembled to one end of the spool. A valve liner houses a portion of the spool. The spool is configured to move back and forth within the valve liner. The metering valve is biased in a closed position in which the outlet flow port is disposed entirely within the valve liner. The valve is opened when the spool slides within the valve liner such that some portion of the outlet flow port extends beyond an end of the valve liner. The retainer has a stepped portion configured to abut an end of the retainer at a fuel flow pressure below the expected maximum fuel flow pressure to be used in the fuel nozzle metering valve.Type: GrantFiled: January 17, 2023Date of Patent: April 2, 2024Assignee: Woodward, Inc.Inventor: Jimroy A. McCormack

Patent number: 10711699Abstract: A torch igniter includes an auxiliary fuel injector; an ignition source; and an igniter body carrying the auxiliary fuel injector and the ignition source. The igniter body includes an auxiliary combustion chamber having a side wall extending axially from a first end wall to a second end wall. In some examples, at least a portion of the side wall includes a distributed pattern of cooling apertures, with each of the cooling apertures extending obliquely from an outer surface of the side wall to an inner surface of the side wall. In some examples, the second end wall defines a fluid outlet leading to an outlet tube in fluid communication with the primary combustion chamber, at least a portion of the outlet tube including a distributed pattern of dilution apertures.Type: GrantFiled: July 7, 2017Date of Patent: July 14, 2020Assignee: Woodward, Inc.Inventors: Bidhan Dam, Jimroy McCormack, Fei Philip Lee, Conor Riordan, Logan Oonk, Erik Pederson, Michael Stratton

Patent number: 10704469Abstract: A torch igniter includes an auxiliary fuel injector; an ignition source; and an igniter body carrying the auxiliary fuel injector and the ignition source. The igniter body includes an auxiliary combustion chamber having a side wall extending axially from a first end wall to a second end wall, the side wall defining an interior cavity between the first and second end walls. The igniter body further includes a premixing cup residing within the interior cavity including a cylindrical wall radially surrounding the auxiliary fuel injector and an auxiliary air inlet, the cylindrical wall of the premixing cup protruding axially outward relative to the first end wall of the auxiliary combustion chamber through a portion of the interior cavity to delineate a premixing zone radially inward of the cylindrical wall and a recirculation zone radially outward of the cylindrical wall.Type: GrantFiled: July 7, 2017Date of Patent: July 7, 2020Assignee: Woodward, Inc.Inventors: Bidhan Dam, Jimroy McCormack, Fei Philip Lee, Conor Riordan, Logan Oonk, Erik Pederson, Michael Stratton

Patent number: 10584639Abstract: A gas turbine combustor assembly includes a primary combustion chamber in fluid communication with a primary fuel injector and a primary air inlet. A torch igniter is carried by the primary combustion chamber, and includes an auxiliary combustion chamber housing comprising a mixing chamber and a throat region converging downstream of the mixing chamber. An air swirler including a plurality of swirl openings surrounding an outlet of an auxiliary fuel injector is coupled to the auxiliary combustion chamber proximate the mixing chamber. An ignition source projects into the mixing chamber of the auxiliary combustion chamber.Type: GrantFiled: August 18, 2015Date of Patent: March 10, 2020Assignee: Woodward, Inc.Inventors: Bidhan Dam, Jimroy McCormack, Erik Pederson, Fei Philip Lee, Paul Hicks
