Several life management and extension (LM&E) studies for hot section components of various turbines are performed at Southwest Research Institute (SwRI). The methodology for LM&E includes:
- Condition Assessment
- Material and coating degradation
- Material properties evaluation
- Nondestructive evaluation
- Stress Analysis
- Mechanical analysis
- Aero and thermal stress analysis
- Vibration analysis and frequency testing
- Life Evaluation
- Failure modes
- Life evaluation methodology
Turbine Condition Assessments
SwRI performs condition assessments of hot section components to evaluate the extent of base material and coating degradation and to help clients make run, repair, and replacement decisions.
We have developed algorithms and computerized programs for life prediction, life management, and life extension of gas turbine engines to increase component usage, maximize engine availability, and reduce maintenance costs.
We have also developed methodologies and software to predict the life of gas turbine hot section blades for GE frame gas turbines. Extensive materials testing of new and service-exposed components was conducted to develop pertinent material properties, which were used in the life assessment algorithm and software, GTD LIFE. Using these data in their turbine fleet life management program, clients can realize economic gains by prudently scheduling the inspection and maintenance intervals while maintaining good availability and reliability of their engines.
SwRI can offer you a full range of capabilities and experience in gas turbine technology including becoming an extension of your engineering department.
