Aircraft noise optimization method of continuous descending approaching based on ant colony algorithm

Abstract

The invention discloses an aircraft noise optimization method of continuous descending approaching based on an ant colony algorithm. The method comprises steps of firstly selecting noise sensitive points and coarsely selecting a noise optimal CDA basic approaching program; then, based on a PBN approaching reference program, constructing a continuous descending approaching nominal flight track control module, and carrying out correction; then, determining constraints borne by an aircraft in a continuous descending process and dividing a noise optimization transition space and a noise optimization approaching space so as to obtain selectable four-dimensional CDA flight track searching libraries corresponding to different aircraft states; and finally, by taking the minimal noise of the aircrafts in the approaching process as a target, establishing an aircraft continuous descending approaching noise optimization model, and listing an optimal descending approaching flight rack corresponding to different types of aircrafts, different operation states and different weather conditions. According to the invention, based on aircraft performance, the initial state and the weather conditions, the flight tracks of the continuous descending approaching of the aircraft are dynamically adjusted and reference is provided for an environmental protection level of the aircraft at a descending stage in a terminal region.

Description

technical field [0001] The invention belongs to the field of aircraft operation information perception and identification, and relates to an ant colony algorithm-based noise optimization method for aircraft continuous approach stages, in particular to approach program optimization selection targeting noise sensitive points, continuous descent approach nominal Track control modeling, noise optimization transition space / approach space design and continuous descent approach noise optimization solution methods. Background technique [0002] As air traffic continues to grow, airport runways will handle higher traffic volumes, making aircraft noise pollution a growing concern for residents living around airports. Continuous Descent Approach (CDA), as a new approach approach, can effectively reduce noise pollution. With the CDA approach, the aircraft can maintain a higher altitude when landing, reducing the power of the aircraft, thereby significantly reducing the noise impact of ...
