Background - This project is investigating the application of advanced statistical analyses and decompositions for the interpretation of complex signals found in transient jet engine performance data. The need for these types of analyses arose during a previous internal research project that explored the analysis of transient jet engine performance data for improved Engine Trending and Diagnostics (ET&D) purposes. Although the immediate application of these methods will be for transient engine data, the methods could be applied to data from many different systems operating under various conditions. The methods should also provide for more precise detection and decomposition of steady-state data, which would be an enhancement of capabilities provided by SwRI-developed tools that are currently in use by customers.
Approach - The objective of this project is to apply new statistical tools to analyze and interpret the various complex signals that exist in transient data. Overcoming these challenges in a transient data set will require exploring new methods of statistical analysis and fusing those results with prior knowledge and expertise of the subject system.
Major Tasks include:
Accomplishments - Preliminary results indicate these advanced detection and decomposition algorithms will greatly aid the analysis of complex signals originating from transient jet engine performance data. These improvements directly influence the detection, diagnostic and prognostic capabilities applied to gas turbine engines and other monitored systems.
