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.
