Abstract

controlledwindmilling conditions is numerically investigated. Initially, the ram air is equipped with a classic fan, only conceived to work as a compressor. The purpose of the new fan is to be able to work in antagonist functioning modes with high efficiencies: a compressor mode during which energy is given to the flow and a turbine mode (windmilling conditions) where energy is extracted from it. A numerical study was conducted to check the results predicted by the design tool on the new geometry. Good efficiencies were observed in both compressor and turbine modes, confirming the relevance of the design method. Afterwards, a thorough local comparison was achieved between the two fans to better understand the flow topology of the new design.
