Abstract: The review of semi-natural stands for studying the characteristics of the various systems of Gas Turbine Engine (GTE) is represented in this study. The study shows the semi-natural test bench for investigation the characteristics of fuel supply and control systems developed in Samara State Aerospace University (National Research University). The stand is different from the described analogs both using the mathematical model of the GTE and real aggregates. Some aspects of controlled object mathematical simulation and the basic approaches for its implementation are described. Developed bench is reported to allow us to simulate and define performances of whole fuel system and particular aggregates in steady-state and transient regimes of operation in the closed and open loop circuits. Additionally, it allows us to perform the analysis of available control system stability margins to carry out the interaction of separate circuits and aggregates to study influence of perturbations and external factors on control system fail safety.
