Flying area layout planning method for atmospheric environment impact

Abstract

The invention discloses a flying area layout planning method for the atmospheric environment impact. The method comprises the steps that the number of runways and the orientation value range of each runway are determined by predicting airport future flights and meteorological information data, and corresponding different airport flying area layout schemes are made according to the runway number and orientation combination scheme; the discharge amount of pollutants of NOx, SOx, CO, HC and PM in the four stages of approaching, taxiing, takeoff and climbing of a plane is calculated; an AERMOD atmospheric diffusion model is built to simulate discharged pollutant diffusion, caused by the different flying area layout schemes, in the four stages of approaching, taxiing, takeoff and climbing of the plane separately, and the concentrations of the pollutants in an evaluation area are obtained; corresponding pollutant diffusion areas are calculated according to the pollutant concentrations, and the flying area layout planning scheme corresponding to the smallest area is the flying area layout planning scheme having the minimal impact on the atmospheric environment. Accordingly, the impact of an airport on the surrounding atmospheric environment can be reduced.

Description

technical field [0001] The invention specifically relates to a layout planning method of an airport flight area facing the influence of the atmospheric environment. Background technique [0002] The effect of the airport on the surrounding atmospheric environment is mainly affected by the layout of its flight area and the flow of flights. Airport flight area refers to: the site used for aircraft take-off, landing, taxiing and parking, including runways, lifting belts, safety areas at the end of runways, taxiways, aprons and areas around the airport that have restrictions on obstacles. The most important emission source, its emission is mainly concentrated in the main part of the flight area, namely: the runway, taxiway and apron area, and the pollutants emitted by the aircraft during the approach, taxi, take-off, and climb based on the layout of the airport flight area After transmission and diffusion, it will have a certain impact on the atmospheric environment near the gr...
