Особенности компьютерного моделирования рабочего процесса малоразмерных газотурбинных двигателей

Abstract

The article describes the sizing classification of gas turbine engines according to corrected mass flow rate. Has been indicated the sizing effect on efficiency of turbocompressor, trunking loss, combustion efficiency and engine specific weight. Has been developed the mathematical model of thermodynamic analysis that taking into account the sizing effect. The model has been created in the computer-aided system "ASTRA". The classification of thermodynamic analysis models of gas turbine engine has been also indicated.
