Optimization of open counter – rotation fan blades on the basis of solving a 3D Navier-Stokes inverse problem with the aim of reducing tonal noise

The paper presents some results of gas-dynamic and aero-acoustic optimization of the blade profile of an unducted counter-rotation fan (CRF) by using a 3D inverse problem. It was established on the basis of unsteady-state 3D Navier-Stokes equations that the interaction of tip vortices of the first a...
