摘要

Meridional axisymmetric (2D) approach for steady and transient working mode simulation in turbojet bypass engines is presented. The developed approach is referred as high-level model, based on real 3D geometry of engine flow passage. This simulation includes all main actual effects, determining working process, such as viscous losses, feeding and burning of fuel, leakages from a flow passage, selecting and blowing out of cooling air, rotor inertia, air humidity. The approach allows calculating engine performances and predicting the influence of main parameters on engine efficiency and flowing structure.
