The aerodynamic model and solution strategy underlying the linearized unsteady aerodynamic analysis, LINFLUX, are described, and this analysis is applied to predict the acoustic responses of a fan exit guide vane (FEGV) to rotor wake excitations. Numerical results are given for the unsteady pressure responses of the FEGV, including the modal pressure responses at inlet and exit. In addition, predictions for the modal and total acoustic power levels at exit are compared with measurements. The present results indicate that a linearized Euler model should be useful in the aeroacoustic design process, and for assessing the three-dimensional flow physics relevant to blade-row noise generation and propagation.
