Design method of aerial overpass structure

Abstract

The invention discloses a design method of an aerial overpass structure. The design method includes: needing to use the number of flight levels; updating traffic flow data; calculating complexity as well as collision risk values and graded index values of aerial intersection; judging which route requires a new aerial overpass; calculating the operation distance of the aerial overpass; calculatingbridge radius of adjacent aerial intersections and judging whether the route distance S2 between the aerial intersection and the adjacent aerial intersections is smaller than L'1+Lp+L1 or not and thelike. The design method has the advantages that the problem about which route to construct the aerial overpass and how many flight levels need to construct when an aircraft enters or leaves the aerialintersections can be solved; for the aircraft 'entering' the aerial intersection direction, the fact whether or not the distance from a section or a zone boundary is sufficient for the aircraft to change attitude once can be extended to the fact whether or not the route distance between the two neighboring aerial intersections can meet the minimum change in attitude; therefore, a basis is provided for the principle of coordinate distribution at the flight levels, and reference is provided for regulatory authorities to sign relevant agreements.

Description

technical field [0001] The invention belongs to the technical field of civil aviation, and in particular relates to a method for designing an aerial overpass structure. Background technique [0002] Air intersections are an important part of the airway network. Air overpasses are a control strategy used by Chinese controllers when deploying conflicts at busy air intersections. Safety plays an important role in reducing the controller's load. However, due to the fact that there are more and more aerial overpasses at present, and they have evolved into "air viaducts" in some places, regardless of the flow and airspace structure, the height limit is "limited to the boundary" and continues to spread, and "living overpasses" have become "dead In addition, it is impossible to flexibly adjust the height level according to the actual level occupancy, which seriously affects the efficiency of the air traffic control system. [0003] Because the air overpass is a way for my country'...

AI Technical Summary

Problems solved by technology

The literature on aerial overpass research is only an article "The Impact of One-way Circulation Airway Reconstruction on Air Overpass" published by Yang Chao, Air Traffic Management Bureau of the Civil Aviation Administration of China in 2013; there is no direct reference to deal with the same problem abroad

[0004] At present, the design of the structure of the aerial overpass mainly relies on the experience of the controllers in the control unit, and there is no clear method
