  • 1 Effects of Installation on the Downstream Fan Noise from Dual Flow Turbojets

    The fan of a turbojet is one of the dominant sources of the noise generated by aircraft in the take-off and approach phases. Consequently, predicting fan noise with a view to reducing it has become a priority research topic... To this end, Onera has already carried out several experimental and numerical studies with the aim of characterizing the shielding effect that a tail plane might have on" the downstream" fan noise of a dual flow nozzle
