Embodiment Construction

[0029] Please refer to figure 1 As shown, the present invention is based on the noise reduction flight program design method of aviation noise limit area fitting and comprises the following steps:

[0030] Step 1: Collect information and process data

[0031] Collecting information and processing data is a fundamental part of the whole invention. In the present invention, the information that needs to be collected specifically includes: (1) typical peak day flight information data (comprising flight schedule and flight operation data) preserved in the air traffic control center information system and airport flight operation control system; (2) relevant Urban construction control planning and geographic information system database to obtain relevant geographic information data (longitude, latitude, elevation information) of corresponding noise sensitive points (schools, hospitals, residential areas); (3) Aeronautical Information Publication (AIP, Aeronautical Information Publ...

Abstract

The invention discloses a de-noising flight program design method based on aerial noise restricted area fitting. The method comprises the following steps: acquiring the flow, flow direction and model data of target airport prediction traffic flow; converting the noise level requirements of corresponding sensitive points such as schools and hospitals around an airport into an aerial noise restricted area in a three-dimensional space; establishing a spatial curved surface equation of a restricted area boundary by adopting least square fitting; and solving a tangent line from an initial way point to a curve surface to obtain a de-noising flight program with an optimal distance. Through adoption of the de-noising flight program design method, the conventional problem that the ground aerial noise can only be computed after design of the flight program is solved; the design working efficiency is increased; and the noise flight program design accuracy is increased through establishment of a noise restriction program solving model.

Description

Technical field: [0001] The invention relates to a method for designing flight procedures of civil aviation airports, in particular to a method for designing noise-eliminating flight procedures based on aviation noise restricted area fitting. Background technique: [0002] In recent years, with the continuous increase in the number of flights at airports, the problem of aircraft noise nuisance has become a hot issue in society, and more and more attention has been paid to reducing the impact of aircraft noise. There are two main methods in the existing noise reduction flight program design: one is to achieve the effect of noise reduction through noise source control, and the other is to fly around the noise-limited area to reduce the noise impact of sensitive points. [0003] The noise source control method is based on the noise reduction program framework proposed by the International Civil Aviation Organization (ICAO, International Civil Aviation Organization). The aircraf...
