Summary/Abstract: In the current paper is carried out profiling of the fan stage of a high-bypass turbofan engine. The law of permanent circulation of the flow withentpreliminary rotation in front of the working wheel is applied. In order to provide acceptable values of the parameters of the stage there is a linear reduction of the work transferred to the air flov in the area of the first stage. Supersonic profiling of the cross sections of the biggest radiuses is applied.
