Patent number: 11920500Abstract: A passive flow modulation device for a machine defining an axial direction and a radial direction, the passive flow modulation device including: a first ring with a first coefficient of thermal expansion; a second ring disposed coaxially with the first ring and positioned at least partially inward of the first ring along the radial direction, spaced from the first ring along the axial direction, or both, the first ring, the second ring, or both defining at least in part one or more passages, the second ring with a second coefficient of thermal expansion that is less than the first coefficient of thermal expansion to passively modulate a size of the one or more passages during operation.Type: GrantFiled: August 30, 2021Date of Patent: March 5, 2024Assignee: General Electric CompanyInventors: Steven Douglas Johnson, Yu-Liang Lin, Craig Alan Gonyou, Scott Alan Schimmels, Jeffrey Douglas Rambo, Brian Gregg Feie

Patent number: 11879360Abstract: Nozzle segment assemblies for gas turbine engines include an outer band, inner band, and at least one airfoil body between the outer band and inner band. The airfoil body includes an outer end extending through the outer band and having an outer end reinforced wall portion engaging with the outer band and an inner end extending through the inner band and having an inner end reinforced wall portion engaging with the inner band. A thickness of the outer end and inner end reinforced wall portions are each greater than a thickness of a central wall portion of the airfoil body to reduce stresses in the airfoil body. The outer band, the inner band, and the airfoil bodies are ceramic matrix composite (CMC) materials. Direct mounting of the airfoil bodies to the inner and outer hangers of the nozzle further reduce stress.Type: GrantFiled: October 30, 2020Date of Patent: January 23, 2024Assignee: General Electric CompanyInventors: Brian Gregg Feie, Alexander Martin Sener, Mark Holleran, Douglas G.

Patent number: 10800128Abstract: Composite components having a T or L-shaped configuration that include features that reduce void defects between abutting laminate portions and provide improved mechanical properties are provided. Methods for forming such components are also provided. In one exemplary aspect, a composite component defines a first direction and a second direction and includes a wedged-shaped noodle at a joint interface between an abutting first laminate portion extending along the first direction and a second laminate portion extending along the second direction. The noodle has a first surface that is angled with respect to the second direction. At least one of the plies of the second laminate portion terminate and attach to the angled first surface of the noodle.Type: GrantFiled: January 24, 2018Date of Patent: October 13, 2020Assignee: General Electric CompanyInventors: Brian Gregg Feie, Darrell Glenn Senile, Gregory Scott Phelps, Thomas Samuel Holaday

Patent number: 10738628Abstract: A ceramic matrix composite (CMC) component including a subcomponent, such as a band flowpath, a load bearing wall and a wall support, each comprised of a ceramic matrix composite (CMC) including reinforcing fibers embedded in a matrix. The CMC component further including at least one mechanical joint joining the subcomponent, the load bearing wall and the wall support to form the CMC component. The reinforcing fibers of the load bearing wall are oriented substantially normal to the reinforcing fibers of the subcomponent and the wall support. Methods are also provided for joining the subcomponent, the load bearing wall and the wall support to form a mechanical joint.Type: GrantFiled: May 25, 2018Date of Patent: August 11, 2020Assignee: GENERAL ELECTRIC COMPANYInventors: Sara Saxton Underwood, Douglas Glenn Decesare, Michael Ray Tuertscher, Daniel Gene Dunn, Douglas Melton Carper, Brian Gregg Feie

Patent number: 10309240Abstract: An airfoil assembly for a gas turbine engine and a method of transferring load from the ceramic matrix composite (CMC) airfoil assembly to a metallic vane assembly support member are provided. The airfoil assembly includes a forward end and an aft end with respect to an axial direction of the gas turbine engine. The airfoil assembly includes a radially outer end component, a radially inner end component, and a hollow airfoil body extending therebetween. The radially outer end component including a radially outwardly-facing end surface having a non-compression load-bearing feature extending radially outwardly and formed integrally with the outer end component, the load-bearing feature configured to mate with a complementary feature formed in a radially inner surface of a first airfoil assembly support structure and selectively positioned orthogonally to a force imparted into the airfoil assembly.Type: GrantFiled: July 24, 2015Date of Patent: June 4, 2019Assignee: General Electric CompanyInventors: Bryce Loring Heitman, Darrell Glenn Senile, Michael Ray Tuertscher, Greg Scott Phelps, Brian Gregg Feie, Steven James Murphy
