Real-Time Turbine Engine Diagnostic System

"Our innovation is a real-time engine diagnostic system capable of simultaneously monitoring for, distinguishing between, and classifying the source and type of sensor, engine and facility faults. The diagnostic system will be integrated with AEDC's DataValidation Manager and test data management systems to provide online engine and facility health management. The software elements consist of: a diagnostic decision manager that performs high-level fault and event classification and diagnostic decisionprocessing; a user-definable predictive model used as an online parameter estimator to provide analytical signal estimates (expected values) given the current observed signal data values; a set of statistical and analytical event and fault detectors thatare used to evaluate data signals for planned and unplanned operating events; and a model manager used to configure, train, and operate the software from the Data Validation Manager interface. The online diagnostic system will enable test engineers anddata analysts to quickly and cost effectively build and validate sophisticated software for automated data quality assurance and certification of engine systems and components. This will enable faster and more accurate decisions to certify or maintain anengine system in both test and operational environments."
