点融合技术下的机场终端区航空器噪声研究

Research on Aircraft Noise in Airport Terminal Area Based on Point Fusion Technology

随着人民生活水平的不断提高,民航旅客吞吐量和空中交通流量也逐年增加。机场终端区是进离场航空器最繁忙的空域,航空器的尾气排放导致该区域的环境污染问题日益,并且由于进场程序的限制,管制员通过雷达引导进行机动飞行的时候导致多余的燃油消耗,同时也造成管制员工作负荷大的问题,原有的进场程序已不能适应民航的快速发展。点融合系统(PMS,Point Merge System)作为一种新型的进场程序,成为优化空域结构、减轻管制负荷、改善机场终端区域环境和提升终端区运行效率的新技术。以双流机场终端区为例子,结合双流机场终端区域环境和所设计的双流机场PMS进近程序,使用航空环境设计工具(Aviation Environmental Design Tool,AEDT)对点融合系统PMS和区域导航(Area Navigation,RNAV)进场程序进行仿真建模,并对其不同运行模式下的噪声影响进行了对比,为点融合技术在国内环境研究方面推广助力。

With the continuous improvement of people's living standards,civil aviation passenger throughput and air traffic flow have also increased year by year.The terminal area of the airport is the busiest airspace for aircraft entering and leaving the airport.The exhaust emission of aircraft has led to the increasing environmental pollution problem in this area.Due to the limitation of the entry procedure,the excess fuel consumption is caused when the controllers conduct maneuvering flights under the guidance of radar.At the same time,it also causes the problem of heavy workload of controllers.The original entry procedure can no longer adapt to the rapid development of civil aviation.As a new approach procedure,point fusion system(PMS)has become a new technology to optimize the airspace structure,reduce the control load,improve the airport terminal area environment and improve the terminal area operation efficiency.Taking the terminal area of Shuangliu Airport as an example,combined with the terminal area environment of Shuangliu Airport and the PMS approach program of Shuangliu Airport,this paper uses AEDT to simulate and model the PMS and RNAV approach program,and compares the noise impact under different operation modes,so as to help promote the point fusion technology in domestic environmental research.
