High Cycle Fatigue Analysis of Integrally Rotors Navy STTR FY2006 Sol No.: Navy STTR FY2006 Topic No.: N06-T015 Topic Title: High Cycle Fatigue Analysis of Integrally Rotors Proposal No.: N064-015-0023 Firm: Rotordynamics-Seal Research 3302 Swetzer Road Loomis, California 95650 Contact: Charles Wu Phone: (916) 660-0444 Web Site: www.rsr.com Abstract: A new approach is proposed for high fidelity analysis of aeroelastic characteristics of integrally bladed rotors. This new multiscale approach for nonequilibrium flow path analysis will yield high fidelity solutions including all turbulence scales at a fraction of the computational cost of RANS. Integration of this advanced capability within an existing multidisciplinary, multifidelity, transient modeling and simulation environment will provide the most accurate solution for critical inputs for fatigue life calculations. The proposed effort also includes substantial experimental validation of the analysis results using an existing high speed, high frequency dynamic test facility. Benefits: Faster and more accurate solution of fluid structure interaction problems. Return
