Integrated life measurement and diagnostics for gas turbine engines

摘要

Accurate component life measurement and integrated diagnostics that reflect component design principles is critical to optimizing the structural integrity of gas turbine engine components once installed in an enine. State-of-the-art technologies such as "virtually sensing" currently numeasured engine parameters such as turbine entry temperature (TET) are now being used in critical component lifing algorithms to enhance structural integrity assessments in a timely manner. In addition, complex finite-element and empirical models of structural and performance related engine areas can now be accessed in a real-time monitoring environment. Integration and implementation of these proven technologies presents a grat opportunity to significantly enhance current engine health measurement capabilities and safely extend engine component life.
