Patent number: 11333078Abstract: A method and decoupler for disengaging an output shaft from an engine in a back drive event with a backdrive decoupler. The backdrive decoupler includes an output shaft, drive shaft wherein the output shaft is selectively coupled to the drive shaft. Permanent magnets are used to transmit torque from the drive shaft to the output shaft. In a backdrive event, the decoupler decouples the output shaft from the drive shaft by uncoupling the torque transfer.Type: GrantFiled: October 30, 2017Date of Patent: May 17, 2022Assignee: GE Aviation Systems LLCInventors: Subrata Nayak, Pallavi Tripathi, David Raju Yamarthi, Navin Soni, Dhiraj Thakare, Shiloh Montegomery Emerson Meyers, David Allan Dranschak
