Non-Integrated Gas Turbine Engine Diagnostics Tradeoff Analysis.
Abstract
Diagnostic equipment and techniques to be included in a non-integrated system to detect and isolate the four most prevalent malfunctions in Navy aircraft gas turbine engines were selected. Each of twenty-five candidate elements were considered on the basis of technical feasibility, cost-effectiveness, and diagnostic need. Gas path analysis, with trending, and borescope inspection were selected as the most effective methods to diagnose the leading engine malfunctions (63%), foreign object damage and hot section distress. Other elements to be included in the proposed embryonic system are called oil analysis, time temperature recording indicator/low cycle fatigue counters, vibration testers, trim testers, test system vibration equipment, vibration signal analysis equipment, temperature sensing system tester, and Jetcal Analyzer. Oil anaylysis techniques being developed indicate a significant improvement compared to spectrometric analysis of diagnostic purposes. A summary of specific elements for utilization at each of three levels of maintenance and an engineering development plan with proposed implementation milestones are included. (Author)
