Patent number: 11577461Abstract: An additive manufacturing (AM) system includes a housing defining a chamber and a build platform disposed in a lower portion of the chamber. The AM system includes an upper gas inlet disposed in a side-wall and in an upper portion of the chamber and configured to supply an upper gas flow parallel to the build platform. The AM system includes a lower gas inlet in the lower portion of the chamber, wherein the lower gas inlet includes one or more pairs of dividing walls extending from the side-wall toward the build platform and configured to guide the lower gas flow at one or more flow angles with respect to the build platform. The AM system includes at least one gas delivery mechanisms to regulate flow characteristics of the upper and lower gas flows, and includes a gas outlet to discharge the upper and lower gas flows from the chamber.Type: GrantFiled: May 25, 2021Date of Patent: February 14, 2023Assignee: General Electric CompanyInventors: Christian Wakelam, Rene du Cauze de Nazelle, Christian Aalburg, Florian Hoefler, Jonathan Ong

Patent number: 11242770Abstract: Aspects of the disclosure generally relate to a turbine center frame for a turbine engine through which a flow path extends. The turbine center frame can include an inner wall radially spaced from an outer wall, with the inner and outer walls extending between an inlet and an outlet, and with the outlet downstream of the inlet with respect to the flow path. A set of circumferentially-spaced airfoils can extend between the inner wall and the outer wall.Type: GrantFiled: April 2, 2020Date of Patent: February 8, 2022Assignee: General Electric CompanyInventors: Jonathan Ong, Christian Thomas Wakelam, Andreas Peters

Patent number: 10344602Abstract: A transition duct includes fairings with transition duct flow passage and hollow fairing airfoils extending between outer and inner walls of fairings and means for smoothing pressure gradients along inner wall. One means is a contracting duct flow area of flow passage from leading edge of fairing airfoil to about 30% of fairing chord. Leading edges of fairing airfoil intersect outer walls aft of regions of high curvature of outer walls. Leading edges may curve axially aftwardly and radially into fairing airfoils and transition duct flow passage between radially outer and inner walls from radially outer and inner intersection points. Transition duct downstream second area/upstream first area may be greater than about 1.35. Turbine center frame may include outer ring coupled to central hub with struts extending through hollow airfoils.Type: GrantFiled: April 18, 2016Date of Patent: July 9, 2019Assignee: General Electric CompanyInventors: Harjit Hura, Paul Hadley Vitt, Brian David Keith, Jonathan Ong
