F136 Low Pressure Turbine HCF Evaluation and Mitigation using Innovative Non-intrusive Measurement Techniques

The focus of the Phase I effort is to determine the feasibility of using new and innovative high temperature probe tools to evaluate the HCF issues directly related to a military turbofan low pressure turbine application. Specific focus of the Agilis efforts will be to develop increased life probes that will be capable of withstand long-term exposure to the aggressive operating environment of the turbine. The Phase I Option will be focused on development of innovate enhancements to the Agilis arrival time software to allow evaluation of the HCF environment of the blades against initial analysis predictions and specific component design fatigue limitations, and to allow evaluation of the changes in the blade HCF environment and vibratory performance over the engine operating life.
