Abstract: Numerical analysis results are shown in the noise source, which is the result of unsteady aerodynamic interaction of turbine rims of experimental engine fan. Q3d-method of tracking of gas flows streams was used for numerical analysis. The method used has been developed for accounting the 3-D effects of gas flows in turbo machinery. Calculations have been made in an absolute coordinate system connected with turbine stator. As nonadjacent impellers had identical numbers of blades, the calculations have been performed with their different relative circumferential arrangement. General conclusions have been drawn about the possibility of suppressing the generated noise at the source.
