Abstract
This paper describes a number of hardware-inloop (HIL) test benches for investigation of both gas turbine engine's (GTE) fuel and control systems. Developed HIL test bench with the virtual model of GTE for research of fuel supply and control systems characteristics is described. An aggregate composition of hydromechanical system and the methodology of the HIL testing technique are presented. Developed test bench is better than analogs by both using the mathematical model of the GTE and full-scale aggregates. Some aspects of controlled object mathematical simulation and the basic approaches for its implementation are described. Developed bench allows us to simulate and define performances of whole fuel system and particular its aggregates in steady-state and transient operating regimes 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.
