Patent number: 11715450Abstract: An acoustic panel is provided that includes a perforated first skin, a second skin and a core. The core is connected to the perforated first skin and the second skin. The core includes a plurality of chambers and a plurality of septums respectively arranged with the chambers. The chambers include a first chamber that extends vertically between the perforated first skin and the second skin. The septums include a first septum that extends laterally across the first chamber. The first septum includes a first septum orifice. The first septum tapers laterally inward towards the first septum orifice as the first septum extends vertically towards the second skin.Type: GrantFiled: December 22, 2020Date of Patent: August 1, 2023Assignee: Rohr, Inc.Inventors: Marc W. Quesada, Jose S. Alonso-Miralles, Michael Scamardo, Kathryn Mireles, Richard S. Alloway, Luby Weaver, Yves Klett

Patent number: 11300075Abstract: A mechanical connection system is provided that includes a ceramic skin panel, at least one bushing, and at least one bolt. The ceramic skin panel includes a first surface, a second surface, and at least one aperture extending between the first surface and the second surface. The aperture has an axial centerline, a chamfered portion contiguous with the first surface, and an axial portion contiguous with the second surface. The chamfered portion includes a tapered surface disposed at a first angle such that a line extending along the tapered surface intersects the axial centerline at a plane of the second surface. The bushing has a housing and a collar. The housing is configured to mate with the chamfered portion of the aperture disposed within the ceramic skin panel. The collar is configured for engagement with the housing.Type: GrantFiled: March 12, 2019Date of Patent: April 12, 2022Assignee: Rohr, Inc.Inventors: Richard S. Alloway, Vijay V. Pujar, Jinqiu Lu, Adam Saunders, Gary E. Bowman

Patent number: 9784215Abstract: A ceramic turbine engine exhaust component, such as a ceramic matrix composite (“CMC”) exhaust center body may be positioned around a metallic attachment ring. The attachment ring may have a greater coefficient of thermal expansion than the CMC center body. A plurality of bolts radially-spaced around the circumference of the attachment ring may be inserted through apertures in the center body with a sliding fit, and may be coupled to the attachment ring. The bolts may slide within the apertures, allowing the attachment ring to thermally expand without applying extra loads on the exhaust center body due to the expansion.Type: GrantFiled: November 7, 2014Date of Patent: October 10, 2017Assignee: ROHR, INC.Inventors: Jacques Jinqiu Lu, Chad Franks, Richard S. Alloway

Publication number: 20160265441Abstract: An exhaust system for a gas turbine engine may comprise a titanium alloy substrate. The titanium alloy may comprise IMI 834, titanium 1100, titanium 6242, or Beta-21S. An amorphous silicon oxygen barrier layer may be coupled to the titanium alloy substrate. The amorphous silicon oxygen barrier layer may be deposited by chemical vapor deposition. The exhaust system may have a high creep resistance and be protected from oxidation.Type: ApplicationFiled: November 26, 2014Publication date: September 15, 2016Applicant: ROHR, INC.Inventors: DAVID E.
