Abstract : The objectives of the study were to select sensing techniques capable of providing the best indication of component condition and to verify this selection through laboratory testing on an operating gas turbine engine. Selection was based on a state-of-the-art literature review and an examination of the failure rate and criticality of the engine components. Twelve sensing techniques were selected for test implementation: external/internal sonic/vibration deterministic analysis; ultrasonic bearing detection monitoring, ultrasonic lube, capacitative blade integrity monitoring; combustion and turbine section monitoring; lube dynamic pressure monitoring; lube condition and contamination monitoring; gas path static pressure and temperature monitoring; lube path static pressure and temperature monitoring; spool acceleration monitoring; spool-speed ratio monitoring; ultrasonic casing leak detection; and ultrasonic lube cavitation and valve flow monitoring.
