عنوان انگلیسی Effect of Exhaust Jet from Takeoff Aircraft on the Inlet Distortion of Runway-Crossing Aircraft
چکیده انگلیسی مقاله Runway crossing behind an aircraft has attracted a large amount of interest in recent years. In this work, based on a turbofan engine model, three-dimensional models of the nozzle and inlet are established, and the effects of the jet of the aircraft in front on the inlet of the aircraft behind are studied under different operating conditions using numerical simulations. The results show that at the same distance between the two aircraft, the total pressure decreases as the exit flow rate of the inlet increases, but different flow rates do not lead to different component distributions. For the same flow rate at the exit of the inlet, when the distance increases, the distortion index of the total pressure at the exit of the inlet decreases, and the contents of the component of the airflow entering the inlet from the jet decrease, but those entering the inlet from the far field increase. Through component and isotope identification, the main components of the airflow entering the inlet are oxygen and nitrogen. Based on these results, when studying the effect of the exhaust jet from an aircraft on an aircraft behind, only the maximum idle engine speed needs to be considered, and the effect of the jet components on the inlet can be ignored. The inlet distortion caused by the exhaust flow is more severe in crosswind environments.
