Keywords: multistage fans, forward sweep, inlet distortion

This paper extends the assessment of the performance payoff derived from forward sweep in single stage fans to multistage configurations. The experimental investigation compares the performance of an advanced two-stage fan tested alternately with a radial and a forward swept stage 1 blade with clean inlet and with inlet distortion.
