$99,996Benefit:
The proposed methodology and software will permit an increased reliability of the predicted blade peak stress in experiments which will lead to an improved estimation of their high cycle fatigue life. In turn, improvements in life prediction will permit a longer running life (financial savings) and an increased accuracy in predicting failure (safety improvements) These improvements will be achieved without requiring undue characterization of the blade, i.e. only basic blade geometry information will be necessary, and thus will be usable by all testing facilities focusing on engine/turbomachine. Potential customers of the planned software will thus be Air Force, Navy, and Army but also NASA (NASA Glenn and NASA Marshall). Further, electric utilities, especially in conjunction with EPRI, are also potential users of the software. Note finally that the proposed effort also supports ongoing blade health monitoring programs.
