Airport single-runway orientation selecting method for lowering influence on atmospheric environment

Abstract

The invention discloses an airport single-runway orientation selecting method for lowering the influence on the atmospheric environment. The method comprises the following steps of determining the airport single-runway orientation value range by predicting airport future flights and meteorological information data; calculating the discharge volume of pollutants in the takeoff stage of an aircraft, wherein the pollutants include NOx, SOx, CO, HC and PM; building an AERMOD atmospheric diffusion model, and simulating aircraft pollutants in evaluation areas due to different runway orientations respectively to obtain the concentrations of the pollutants in the evaluation areas; quantifying the influence of all schemes on the atmospheric environment through the diffusion areas of the pollutants, and regarding the minimum area as a decision-making object, wherein the runway orientation corresponding to the minimum area is the runway orientation scheme which has the smallest influence on the atmospheric environment. By simulating the influence on the atmospheric environment due to different orientations of a single runway, the airport single-runway orientation selecting method which has the smallest influence on the atmospheric environment is constructed, so that the influence of emitted pollutants during the takeoff of the aircraft on the surrounding atmospheric environment is lowered.

Description

technical field [0001] The invention specifically relates to a method for selecting the orientation of a single runway at an airport to reduce the influence of the atmospheric environment. Background technique [0002] The amount of pollutants emitted by an aircraft when it takes off on the airport runway accounts for a large proportion of the total amount of pollutants emitted in all stages of ground operation. Moreover, there are mostly open areas near the airport, which promotes the transmission and diffusion of pollutants, which has a certain impact on the atmospheric environment near the ground (below 1000m) around the airport. The continuous increase of flight traffic and the continuous increase of runway utilization will cause this negative impact to become more serious. Since the diffusion of pollutants is closely related to the wind direction, it is necessary to comprehensively consider the relationship between the orientation of the runway and the diffusion of pol...
