Patent number: 9103741Abstract: Methods, systems and computer program products for assessing residual life of an airfoil, which would experience high cycle fatigue failure under at- or near-resonance vibration condition, are provided. The method includes receiving, at a processing system, at least one vibration response parameter associated with the airfoil. The method processes at least one cracked airfoil finite element model. Processing the cracked airfoil finite element model includes accessing the cracked airfoil finite element model, computing a modal stress intensity factor (SIF) of the cracked airfoil finite element model using fracture mechanics based finite element analysis, and computing a vibratory SIF based, at least in part, on the modal SIF and the at least one vibration response parameter. The method then computes a residual life indicator of the airfoil based, at least in part, on the vibratory SIF.Type: GrantFiled: August 27, 2010Date of Patent: August 11, 2015Assignee: General Electric CompanyInventors: Sanghum Baik, Vivek Venugopal Badami, Yogesh Kesrinath Potdar, Adrian G Loghin, Nuo Sheng

Patent number: 8621629Abstract: An intrusion detection system for detecting and defeating unauthorized intrusion within a computer network of an infrastructure element of a high value target, the system including a pre-processor configured to receive data from a computer network of an infrastructure element of a high value target and to output filtered data, a grammar applicator configured to apply grammars produced using a grammar based compression and learning algorithm to the filtered data, a decision making device configured to provide a recommendation based on an input from the grammar applicator as to whether the data in the computer network constitutes an unauthorized intrusion, and an emulator in communication with the decision making device configured to expand a sampling of the filtered data using a polymorphic transformation to allow the decision making device to further analyze the sampled data to determine an unauthorized intrusion. A method and a computer software code are also disclosed.Type: GrantFiled: August 31, 2010Date of Patent: December 31, 2013Assignee: General Electric CompanyInventors: Scott Charles Evans, Yogesh Kesrinath Potdar, Michael Joseph Dell'Anno, Thomas Stephen Markham, Adam Edgar Klingbeil, Robert Boring, Bruce Gordon Barnett

Patent number: 8129041Abstract: An article comprising an article having a first surface and a second surface adapted to come into contact with the first surface and a first protective coating on at least a portion of the first surface. The first protective coating comprises a first coating layer. The first coating layer comprises a first component comprising boron, titanium or chromium and a second component comprising nitrogen or carbon. At least a portion of the first protective coating comes into contact with the second surface when the second surface comes into contact with the first surface. A method for reducing the wear and galling of a first surface of an article comprising applying a coating to the first surface of the article.Type: GrantFiled: May 4, 2007Date of Patent: March 6, 2012Assignee: General Electric CompanyInventors: Farshad Ghasripoor, Guido Felice Forte, Jr., David Ernest Welch, Yogesh Kesrinath Potdar

Patent number: 7715991Abstract: A method for estimating an amount of damages sustained by a component operating in an energy system by monitoring the component is provided. The method includes generating a transfer function that is dependent upon an input of at least one operating condition of the component and an output of a crack-initiation time and/or a crack propagation for at least one critical region. The method further includes receiving data from at least one sensor coupled to the component, wherein the data relates to the at least one operating condition of the component, and inputting the received data from the at least one sensor into the transfer function to calculate at least one of the crack-initiation time and the crack propagation for the at least one critical region. The method also includes recording at least one of the crack-initiation time and the crack propagation on a memory storage device.Type: GrantFiled: May 17, 2007Date of Patent: May 11, 2010Assignee: General Electric CompanyInventors: Yogesh Kesrinath Potdar, David Ernest Welch, David Wing Chau

Patent number: 7596428Abstract: The present application provides for apparatuses and methods for monitoring steam turbine valve assemblies. In one embodiment of the present application a method for monitoring valve assemblies is provided. First, the vibration characteristics of at least one valve assembly prior to operation may be measured. Next, the behavior of that valve assembly may be monitored during operation of the valve assembly, then compared to the vibration characteristics determined prior to operation. Comparing the valve assembly behavior monitored during operation to the valve assembly characteristics measured prior to operation may allow for estimating the stress levels experienced by the valve assembly during operation.Type: GrantFiled: March 29, 2007Date of Patent: September 29, 2009Assignee: General Electric CompanyInventors: Yogesh Kesrinath Potdar, David E.
