*† ‡ This paper presents a detailed analysis of measurements made in the wakes of idealized aircraft engine fan blades with and without trailing edge blowing. New measurements of the mean velocity field around the trailing edge are presented. These reveal that the structure of the trailing edge flow plays an important role in determining the effects of blowing on the wake further downstream. New analysis of two-point measurements made in the wakes further downstream reveal the most likely occurring eddy types, their potential to produce broadband noise, and the effects of blowing upon them. Finally practical prospects for predicting these two-point correlations, and thus the broadband noise source terms are discussed.
