Publication number: 20240151147Abstract: The present disclosure relates to an airfoil assembly for a turbine engine and methods of assembly thereof. The airfoil assembly generally includes a composite airfoil and a spar. The composite airfoil has a pressure side and a suction side extending in an axial direction between a leading edge and a trailing edge defining a chordwise direction and extending radially between a root and a tip defining a spanwise direction and having a span-length. The spar includes a first portion including a first material and a second portion joined at an interface with the first portion. The second portion further includes a second material, different from the first material, joined to the first portion at an interface. The method generally includes joining the first portion with the second portion at the interface; and assembling the spar with the composite airfoil.Type: ApplicationFiled: November 3, 2022Publication date: May 9, 2024Applicant: AIRFOIL AND METHODS OF ASSEMBLY THEREOFInventors: Gary Willard Bryant, Jr., Nicholas Joseph Kray, Ming Xie, Elzbieta Kryj-Kos, Douglas Lorrimer Armstrong, Nicholas M.

Publication number: 20170101878Abstract: A gas turbine engine including a component having a first and a second component that are attached or integrally formed with each other. The first and the second component define an enclosed void. An insert is positioned within the enclosed void which is formed of a material having a relatively low Young's modulus. The insert may prevent resin from filling the enclosed void during assembly/manufacture of the component, while also reducing a weight of the component and an amount of stress on the component. The component may be a fan platform positioned between a plurality of fan blades, an outlet guide vane, or another component of the gas turbine engine.Type: ApplicationFiled: July 19, 2016Publication date: April 13, 2017Inventors: Mingchao Wang, Gerald Alexander Pauley, Courtney James Tudor, Elzbieta Kryj-Kos, Weizeng Kong
