Embodiment 1

[0053] figure 1 A flowchart of a method for calculating the longitudinal separation of an aircraft according to an exemplary embodiment of the present invention is shown, including:

[0054] A. The improved Reich collision model is obtained by adding the influence length of the wake of the strong eddy current field to the longitudinal dimension of the traditional Reich collision model;

[0055] Specifically, different meteorological conditions will affect the dissipation speed of the wake of the front aircraft, and then affect the longitudinal safety separation between the front and rear aircraft. The main meteorological parameter that will affect the wake vortex dissipation rate is the dimensionless turbulent dissipation rate ε * and dimensionless Frequency N * as an input parameter to the dimensionless wake vortex intensity dissipation curve In order to consider the influence of meteorological factors.

[0056] where the dimensionless turbulent dissipation rate ε * T...

Abstract

The invention belongs to the technical field of air control, and relates to an aircraft longitudinal interval calculation method and system and a readable storage medium. The airplane longitudinal interval calculation method provided by the invention comprises the following steps of: adding a strong vortex field wake influence length into a longitudinal size of a traditional Reich collision model to obtain an improved Reich collision model; and solving aircraft longitudinal intervals corresponding to different front and rear aircraft combinations through the improved Reich collision model on the basis of CNS performance in an airspace environment, the aircraft longitudinal intervals being used for airspace planning. According to the aircraft longitudinal interval calculation method and system and the readable storage medium, the strong vortex field wake influence length is added into the longitudinal size of the traditional Reich collision model, the strength of the trailing vortex capable of being borne by a rear aircraft is reasonably considered, and the strength is combined with the CNS performance in the airspace, so that an aircraft longitudinal interval shorter than an interval formulated by ICAO is obtained; and a controller uses the method to guide the interval between a front aircraft and the rear aircraft, so that the interval between the front aircraft and the rear aircraft is reasonably shortened, and the aircraft capacity of the airspace is improved.

Description

technical field [0001] The invention belongs to the technical field of air control, and in particular relates to a method, a system and a readable storage medium for calculating an aircraft longitudinal interval. Background technique [0002] In recent years, my country's civil aviation industry has developed rapidly, and the air traffic capacity is increasing day by day. In order to cope with the increasing flight volume, all parties have made various efforts. On the one hand, some airports adopt the method of laying parallel runways on the basis of the original infrastructure to cope with the difficulties brought about by the increase in flight volume; on the other hand, control units adopt smaller vertical intervals in the terminal control area to improve the operational efficiency of the airport , the longitudinal interval can be the interval expressed by distance between aircraft tracks at the same altitude. At the same time, the International Civil Aviation Organizat...
