【摘要】：随着我国航空运输业的快速发展,航空器在飞行时对环境的影响越来越受到人们的关注,国内外对航空器飞行时环境影响研究主要为航路飞行,对终端区内飞行时的研究甚少,于是本文主要研究了飞行程序运行的环境影响问题。本文主要研究内容和创新有以下几点:首先,根据飞行程序航迹特征对其进行分析,从飞行程序的数据模块、外界环境模块、航空器受力模块以及航空器运动模块这4个方面建立飞行程序运行仿真实施方法;并利用Matlab中Simulink对各模块进行仿真编译,结合某条飞行程序实现对其的仿真。其次,分析国内外的主要噪声评估模型,选择适合于飞行程序运行的噪声评估量,并依据欧洲空管(Eurocontrol)推荐的飞机噪声数据库ANP2.0中的噪声-推力-斜距特征曲线,对其进行插值计算;对已选择的噪声评估量进行速度、侧方衰减、转弯飞行、发动机推力、风影响等方面的修正;提出飞行程序运行噪声评估方法,并利用Matlab进行仿真分析,得到飞行程序运行噪声等值线图。最后,在国际民航组织推荐的污染物基础排放模型的基础上,结合由气象条件的变化引起的推力与燃油流量的变化,实现对基础排放模型的改进;此外,在汽车污染物扩散模型的基础上进行高度和速度的修正,建立了航空器尾气污染物扩散模型,提出飞行程序运行尾气评估方法,并利用Matlab进行仿真分析,得到飞行程序运行污染物分布图。
[Abstract]:With the rapid development of China's air transportation industry, people pay more and more attention to the impact of aircraft on the environment during flight. Therefore, this paper mainly studies the environmental impact of flight program operation. The main contents and innovations of this paper are as follows: first, according to the flight program track characteristics of the analysis, from the flight program data module, the external environment module, The simulation method of flight program operation is established in the following four aspects: aircraft force module and aircraft motion module; The Simulink in Matlab is used to simulate and compile the modules, and a flight program is used to simulate the modules. Secondly, the main noise assessment models at home and abroad are analyzed, and the noise evaluation quantities suitable for flight program operation are selected. According to the noise-thrust-slant characteristic curve of aircraft noise database ANP2.0 recommended by European ATC (Eurocontrol), Carry on the interpolation calculation to it; The speed, side attenuation, turn flight, engine thrust, wind effect and so on are corrected for the selected noise evaluation quantity. The noise evaluation method of flight program running is proposed and simulated by Matlab, and the contour diagram of flight program running noise is obtained. Finally, on the basis of the pollutant base emission model recommended by ICAO, combined with the change of thrust and fuel flow caused by the change of meteorological conditions, the improvement of the foundation emission model is realized. In addition, on the basis of the vehicle pollutant diffusion model, the height and speed of the model are revised, the aircraft exhaust pollutant diffusion model is established, and the evaluation method of the flight program running exhaust gas is put forward, and the simulation analysis is carried out by using Matlab. The pollutant distribution map of flight program operation was obtained.
