Prediction of fan broadband noise

This paper presents a prediction model of the blade trailing-edge noise and its validation from tests carried out on a fixed flat plate at different angles of attack in an anechoic wind tunnel. The comparison between the measured and predicted far-field sound spectra is very good, which confirms the validity of the model. The same approach has been recently applied to a single rotating blade without casing. The paper presents the first experimental results obtained and the work to be done to check the validity of the model in this case.
