The paper provides an overview of a parametric study of fan flow deflectors (FFD) for jet noise suppression. Reductions in sideline and flyover noise at takeoff cycle point provide a total reduction in EPNL as high as 9.6 dB. Correlations of noise reduction versus the turning effort by the deflectors brings out some general trends and help identify promising configurations.
