Abstract: The paper deals with an aircraft supersonic inlet with mixed compression, which has a dual control system, based on the inner total pressure's ratio preservation. The authors have identified the inlet's gas-dynamic behavior, as well as the main control and controlled parameters. One has also built the system's mathematical model, based on system's non-linear motion equations; furthermore, one has established, based on some simplifying hypothesis, the system's linear non-dimensional model, useful for further studies, as well as for some similar inlets' modeling. A system description based on block diagram with transfer functions was also realized. Some simulations were also performed, concerning the system's time behavior (step response), for different cases of control possibilities.
Keywords: Supersonic, Inlet, Speed, Flow rate, Control, Shock wave, Pressure ratio, Flap.
