【摘要】：隨著我國航空運(yùn)輸業(yè)的快速發(fā)展,航空器在飛行時對環(huán)境的影響越來越受到人們的關(guān)注,國內(nèi)外對航空器飛行時環(huán)境影響研究主要為航路飛行,對終端區(qū)內(nèi)飛行時的研究甚少,于是本文主要研究了飛行程序運(yùn)行的環(huán)境影響問題。本文主要研究內(nèi)容和創(chuàng)新有以下幾點(diǎn):首先,根據(jù)飛行程序航跡特征對其進(jìn)行分析,從飛行程序的數(shù)據(jù)模塊、外界環(huán)境模塊、航空器受力模塊以及航空器運(yùn)動模塊這4個方面建立飛行程序運(yùn)行仿真實(shí)施方法;并利用Matlab中Simulink對各模塊進(jìn)行仿真編譯,結(jié)合某條飛行程序?qū)崿F(xiàn)對其的仿真。其次,分析國內(nèi)外的主要噪聲評估模型,選擇適合于飛行程序運(yùn)行的噪聲評估量,并依據(jù)歐洲空管(Eurocontrol)推薦的飛機(jī)噪聲數(shù)據(jù)庫ANP2.0中的噪聲-推力-斜距特征曲線,對其進(jìn)行插值計算;對已選擇的噪聲評估量進(jìn)行速度、側(cè)方衰減、轉(zhuǎn)彎飛行、發(fā)動機(jī)推力、風(fēng)影響等方面的修正;提出飛行程序運(yùn)行噪聲評估方法,并利用Matlab進(jìn)行仿真分析,得到飛行程序運(yùn)行噪聲等值線圖。最后,在國際民航組織推薦的污染物基礎(chǔ)排放模型的基礎(chǔ)上,結(jié)合由氣象條件的變化引起的推力與燃油流量的變化,實(shí)現(xiàn)對基礎(chǔ)排放模型的改進(jìn);此外,在汽車污染物擴(kuò)散模型的基礎(chǔ)上進(jìn)行高度和速度的修正,建立了航空器尾氣污染物擴(kuò)散模型,提出飛行程序運(yùn)行尾氣評估方法,并利用Matlab進(jìn)行仿真分析,得到飛行程序運(yùn)行污染物分布圖。
[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.
