Abstract: The complete non-linear mathematical model and dynamic simulation model based on MATLAB/Simulink of intercooled-cycle gas turbine had been built according to the mechanism of thermodynamic system modelling method, taking the impacts into consideration such as rotational inertia, volume inertia and intercooler's thermal inertia. By analysing the existing problems of the modelling and simulation of the heat exchanger, the mathematical model and simulation model of the on-engine intercooler and off-engine intercooler were built using sub-lumped modelling method. Through the simulation study of fuel supply rate, the best fuel supply rate curve of the intercooled-cycle gas turbine was obtained.
