Patent number: 11591932Abstract: A casing for a bearing of a gas turbine engine includes a shaft extending along an axial direction. The casing includes an attachment feature at a radially outermost portion of the casing. The attachment feature is configured to be coupled to a static frame of the gas turbine engine. The casing further includes a plurality of support arms extend from the attachment feature to a radially innermost portion of the casing. At least one support arm of the plurality of support arms defines an internal cavity. Further, the radially innermost portion of the casing is configured to be coupled to an outer race of the bearing. The casing additionally includes a reinforcing member housed at least partially within the internal cavity of at least one support arm. Moreover, the reinforcing member includes a shape memory alloy material.Type: GrantFiled: July 28, 2021Date of Patent: February 28, 2023Assignee: General Electric CompanyInventors: Ravindra Shankar Ganiger, Praveen Sharma, Shivam Mittal, Bhujabal Prashant Mahadeo, Weize Kang, Richard Schmidt

Patent number: 11420755Abstract: A vibration isolation system for a gas turbine engine. The vibration isolation system includes a first fixed structure and a second fixed structure separate from the first fixed structure. The vibration isolation system further includes a connector coupling the first fixed structure to the second fixed structure. Additionally, the vibration isolation system includes an isolator, including a shape memory alloy material, associated with the connector. The isolator is arranged between the first fixed structure and the second fixed structure such that the isolator reduces vibrations transferred between the first fixed structure and the second fixed structure.Type: GrantFiled: August 8, 2019Date of Patent: August 23, 2022Assignee: GENERAL ELECTRIC COMPANYInventors: Praveen Sharma, Vinod Shashikant Chaudhari, Sivakumar Mahesh, Bhujabal Prashant Mahadeo, Mohan Kannaiah Raju, Ravindra Shankar Ganiger, Jagadisha Pai Nagarmat, Shivam Mittal
