Engine Health Management of Mechanical Systems for High Performance Turbine Engines

ABSTRACT:This effort will advance the Technology Readiness Level of a new vibration sensor and a vibration/ODM data fusion software system to level 7 through lab testing and development as well as seeded-defect testing in 5000 hp industrial turbine engines, long-term testing in similar engines at a local utility company, and 800-hour/2000-cycle testing in the large CAESAR F135 demonstrator engine with Pratt & Whitney.BENEFIT:New vibration sensor for monitoring turbine engine main-shaft bearings which enables earlier detection and isolation of bearing faults.Algorithms which fuse vibration data with data from oil-debris monitors will be developed which will enable a complete, robust, turbine engine health-monitoring system.
