Patent number: 11105712Abstract: A method for fault diagnosis of a bearing includes detecting, using an oil debris monitor (ODM) sensor, ODM data corresponding to an amount of debris flowing downstream from the bearing. The method also includes detecting, using a vibration sensor, vibration data corresponding to vibration of the bearing during use. The method also includes determining, by a controller, a vibration stage flag corresponding to a severity of damage of the bearing based on the vibration data. The method also includes determining, by the controller, a severity level of the damage of the bearing based on a combination of the vibration stage flag and the ODM data. The method also includes outputting, by an output device, the severity level.Type: GrantFiled: April 6, 2018Date of Patent: August 31, 2021Assignee: Raytheon Technologies CorporationInventors: Yan Chen, Danbing Seto, Sheridon Everette Haye, Allan J. Volponi, Zaffir A. Chaudhry, Gregory S. Hagen, Lichu Zhao, Robert H. Luppold

Patent number: 10767563Abstract: Systems and methods for controlling a fluid-based system are disclosed. The systems and methods may include a model processor for generating a model output, the model processor including a set state module for setting dynamic states, the dynamic states input to an open loop model based on the model operating mode, where the open loop model generates current state derivatives, solver state errors, and synthesized parameters as a function of the dynamic states and a model input vector. A constraint on the state derivatives and solver state errors is based a series of utilities that are based on mathematical abstractions of physical laws that govern behavior of the component. The model processor may include an estimate state module for determining an estimated state of the model based on at least one of a prior state, the current state derivatives, the solver state errors, and the synthesized parameters.Type: GrantFiled: November 29, 2018Date of Patent: September 8, 2020Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Boris Karpman, Thomas Niemczycki, Ian Michael Dinsmore, David Sembiante, Robert H.
