What is a primary focus of vibration analysis in gas turbine engines?

The primary focus of vibration analysis in gas turbine engines is to detect potential failures early in the engine's operation. Elevated vibrations can indicate various mechanical issues, such as imbalances, misalignments, or structural weaknesses. By monitoring vibration patterns, engineers can identify abnormal behavior that may signal wear or impending failure before it becomes catastrophic. This proactive approach helps in maintaining operational safety and reliability, reducing downtime and maintenance costs associated with unexpected engine failures. Early detection through vibration analysis is crucial for implementing timely interventions, ultimately leading to improved engine performance and longevity.
