Формирование геометрического облика переходного канала для использования в компоновке более электрического двигателя

Abstract

The text presents the results of creating a computational model and analyzing total pressure losses depending on changes in the flow part geometry of an axially enlarged intermediate housing to accommodate an integrated electric machine. Because of increasing the size, redesigning the racks and reducing their number, it was possible to achieve a decrease in the speeds λ in the area of the periphery of the separator at the compressor inlet and the sleeve section at the fan outlet by ≈ 10% compared to the standard engine transition channel. The calculation results indicate a low sensitivity of total pressure losses due to changes in the geometry of the flow part, which is associated with a smooth change in channel diameters from the inlet to the outlet.
