High Cycle Fatigue Analysis of Integrally Rotors

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.
