摘要

For selecting the optimal number of stages and the distribution of work along the stages at the compressor and turbine design, the method proposed by the authors is considered. The method is based on the introduced concept of an ideal pressure and ideal values of total pressure ratio (increasing in the compressor and decreasing in the turbine) and expressions obtained to calculate the efficiency of compressors and turbines, stages and profile blading in their composition. The method adequacy is confirmed by an example that shows results for two- and three-stage low pressure compressor for bypass turbofan engine calculation.
