Publication number: 20240052755Abstract: A method of controlling an aeronautical gas turbine engine may be performed with an electronic controller. The method may include determining an airfoil pitch control command for at least one of a plurality of airfoils of the aeronautical gas turbine engine based at least in part on an excitation load acting upon the aeronautical gas turbine engine, and outputting the airfoil pitch control command to one or more actuators actuatable to change a pitch angle of the at least one of the plurality of airfoils. The airfoil pitch control command may be configured to augment and/or compensate for the excitation load acting upon the aeronautical gas turbine engine. The method may be embodied by a non-transitory computer-readable medium that includes computer-executable instructions, which when executed by a processor associated with the electronic controller, cause the electronic controller to perform the method.Type: ApplicationFiled: December 15, 2022Publication date: February 15, 2024Inventors: Stefan Joseph Cafaro, Inenhe Mohammed Khalid, James Ryan Reepmeyer, Amit Zutshi, Daniel Edward Mollmann, Arjan Johannes Hegeman, Rafal Sarba

Publication number: 20240052753Abstract: An open rotor engine includes a core engine, a plurality of guide vanes positioned within or extending from the core engine; and a pitch change assembly operably coupled to the plurality of guide vanes. The pitch change assembly includes one or more actuators configured to change a pitch angle of respective ones of the plurality of guide vanes, and a plurality of linkage arms that are respectively movable by actuation of at least one of the one or more actuators. The plurality of linkage arms are directly or indirectly coupled to a corresponding one of the plurality of guide vanes. The plurality of linkage arms may have a length that differs from one another, and such length may orient a displacement or a range of motion of the respective linkage arm to an envelope of rotation about a guide vane axis that differs as between the plurality of guide vanes.Type: ApplicationFiled: December 15, 2022Publication date: February 15, 2024Inventors: Amit Zutshi, Rafal Sarba, James Ryan Reepmeyer, Stefan Joseph Cafaro, Inenhe Mohammed Khalid, Daniel Edward Mollmann, Arjan Johannes Hegeman

Publication number: 20240051656Abstract: An open rotor aeronautical engine may include a core engine, a plurality of unducted airfoils, and a pitch change assembly. The pitch change assembly may include an ensemble actuator assembly and a unitary actuator assembly. The ensemble actuator assembly may have one or more ensemble actuators and a unison ring that is movable by actuation of the one or more ensemble actuators to collectively change a pitch angle of the plurality of unducted airfoils. The unitary actuator assembly comprising a plurality of unitary actuators respectively coupled to a corresponding one of the plurality of unducted airfoils, the plurality of unitary actuators respectively movable to change the pitch angle of the corresponding one of the plurality of unducted airfoils.Type: ApplicationFiled: December 20, 2022Publication date: February 15, 2024Inventors: Amit Zutshi, Rafal Sarba, James Ryan Reepmeyer, Stefan Joseph Cafaro, Inenhe Mohammed Khalid, Daniel Edward Mollmann, Arjan Johannes Hegeman

Patent number: 9896970Abstract: A method and system for a compartment baffle system are provided. The compartment baffle system includes a first baffle portion extending along an axial length of a casing, the first baffle portion extending radially outwardly from an outer surface of the casing and a second baffle portion extending at least partially radially outwardly from the first baffle portion. The second baffle portion further includes a radially inner edge supported by the first baffle portion and a radially outer edge extending proximate an inner surface of a radially outer cowl. The compartment baffle system also includes a gap extending between the radially outer edge and the inner surface.Type: GrantFiled: October 30, 2015Date of Patent: February 20, 2018Assignee: General Electric CompanyInventors: Kyle Andrew Grose, Arjan Johannes Hegeman, Andrew David Kemp, John Michael Pyles

Patent number: 6832617Abstract: A fine filter assembly for a dishwasher includes a filter body having an inlet and an outlet located substantially adjacent to one another, and an extended flow path joins the inlet and the outlet so that essentially an entire length of the filter body is used for filtration. The flow path is sloped from the inlet to the outlet and extends substantially 360 radial degrees around a circular outer perimeter of the filter body. Therefore, wash fluid naturally flows from the fine filter inlet to the fine filter outlet all the way around the filter body, and substantially the entire filter body is flushed when the fine filter is drained and a main pump assembly is energized.Type: GrantFiled: December 22, 2000Date of Patent: December 21, 2004Assignee: General Electric CompanyInventors: Arjan Johannes Hegeman, Gregory Alan Meyer

Patent number: 6752875Abstract: In one aspect, a dishwasher comprising a control mechanism coupled to a sensor for generating an output representative of whether sufficient water has flowed into the dishwasher during a fill operation is described. The dishwasher comprises a tub and a fluid circulation assembly for circulating water in the tub. The control mechanism is configured to determine whether terminate a current wash cycle based on a signal output by the sensor.Type: GrantFiled: August 15, 2001Date of Patent: June 22, 2004Assignee: General Electric CompanyInventors: Jeffrey Thomas Kiesler, Arjan Johannes Hegeman, Michael Lee McIntyre, Gregory Alan Meyer, Christopher Raymond Geisen, Gregory Owen Miller

Patent number: 6698438Abstract: A fine filter assembly for a dishwasher includes a filter body having a soil accumulation trough. The soil accumulation trough defines a substantially helical flow path between a fine filter inlet and an outlet. A natural flow path is therefore provided to efficiently clean fine the filter assembly with downwardly directed fluid jets generated by a lower spray arm assembly. Soil is directed to a fine filter drain tube with relative ease, thereby facilitating use of more efficient use of a drain pump inlet as a soil collection chamber during wash cycles.Type: GrantFiled: December 22, 2000Date of Patent: March 2, 2004Assignee: General Electric CompanyInventors: Arjan Johannes Hegeman, David V. Helmlinger

Patent number: 6641058Abstract: A dishwasher spray arm hub assembly includes a hub having a first central bore extending therethrough and a conduit feed extending therefrom. The conduit feed is in flow communication with the central bore and a venturi insert is disposed in the hub central bore. The venturi insert also includes a second central bore extending therethrough. The first bore and the second bore together form a fluid bypass channel in flow communication with the conduit feed. Therefore, a lower spray arm assembly and a spray arm conduit for upper spray arm assemblies may be simultaneously fed through the hub assembly.Type: GrantFiled: December 28, 2000Date of Patent: November 4, 2003Assignee: General Electric CompanyInventors: Arjan Johannes Hegeman, David V.

Patent number: 6615853Abstract: A fine filter assembly for a dishwasher includes a filter body, a filter screen coupled to the body; and a pressure relief tube. The pressure relief tube includes a substantially vertical portion having an open top for regulating pressure conditions in the filter body, thereby forming a standpipe that regulates pressure in the filter body. A column of fluid in the relief tube balances the operating pressure in the fine filter assembly. Pressure may be regulated in the fine filter assembly up to a maximum pressure determined by the height of the vertical portion of the tube.Type: GrantFiled: January 3, 2001Date of Patent: September 9, 2003Assignee: General Electric CompanyInventors: Arjan Johannes Hegeman, Gregory Alan Meyer
