Keywords: Multistage Fans, Inlet Distortion, Swirl

CFD analysis of flow swirl distortion induced by total pressure and total temperature distortions for two multistage fans is presented. The CFD is validated with engine test data and the flow physics of swirl generation and distortion transfer behavior are discussed.
