Developed tools are useful for preliminary design of gas turbine engines for a wide operational range and control problems solving. Results for a turbojet engine acceleration-stall onset-deceleration-unstall are presented. A multi-sheet map is generated for a wide operational range of the compressor (one sheet for the stable off-design and another one for the rotating stall and reverse flow). The user can model a gas turbine and run steady state and transient simulations. A new model for the simulation of gas turbine engines considering the rotating stall in a compressor is presented. GTSP is a Gas Turbine Simulation Program. Gas turbine combustion is a complex process, and it can be a challenge to achieve accurate and reliable CFD simulation results at a reasonable computational. The developed tool COMPRESSOR_S is verified via comparison against a set of individual compressor stage and multistage compressor experimental maps. A model is capable of predicting the axial compressor performance in the following conditions: stable off-design part-span and full-span rotating stall reverse flow. A new one-dimensional method (implemented in COMPRESSOR_S software) for the prediction of the performance of axial-flow compressors was developed. This software is aimed at providing engineering design personnel who are engaged in marine gas turbine power system design and performance optimization with. A set of models and software tools for the simulation of gas turbine engines considering the rotating stall in a compressor is presented.
