An aeroacoustic investigation was performed to assess the e!ects of adding mass #ow at the trailing edges of stators upstream of an aircraft engine simulator. By using trailing edge blowing to minimize the shed wakes of the stators, the #ow into the rotor was made more uniform, hence reducing the un

In this study, the unsteady, thin-layer, Navier-Stokes equations are solved using a system of patched grids for a rotor-stator configuration of an axial turbine. The study focuses on the plurality of spinning modes that are present in such an interaction. The propagation of these modes in the upstre
Results are presented from a study of directivity and sound focusing effects generated by helicopter rotors encountering parallel and oblique blade vortex interactions (BVI). The primary analysis is performed by using wave tracing to determine ray cones and acoustic lines from source points on the r
