Краткое описание

Detailed analysis of the six-engine fan-stage geometry was carried out from the viewpoint of its gas-dynamic and acoustic parameters. The analysis is based on the three-dimensional gas-dynamic calculations of the rotor-stator interaction in the fan stage of an advanced turbo jet engine. The distributions of the difference of unsteady pressure on the outlet guide vane midsurfaces are regarded as the distributed acoustic sources in the applied approach. The variants with optimal correlation between the gas-dynamic efficiency of the fan stage and its acoustic characteristics were determined.
