| Abstract: | The configuration and working principle of temperature-controlled air supply duct of a kind of fighter ECS (environmental control system) are detailedly introduced. Based on the mathematical model of components, the dynamic simulating model of entire ECS is established by using simulink, one of toolboxes of MATLAB. With the use of the model, the effect of every parameter of the air supply duct, such as the backing pressure of turbine, regulating range of the pulse width modulator as well as the parameters of electric motor, on the dynamic performance of the ECS is analyzed. Regulation of these parameters can improve the dynamic response performance of the system. The conclusion is helpful to design and optimization of the temperature-controlled air supply duct. |
