Flight trajectory path multi-target dynamic planning method

Abstract

The invention discloses a flight trajectory multi-target dynamic planning method, and belongs to the field of air traffic management. The method comprises the following steps of: acquiring information such as an air route network structure, flight segment length, height layer configuration of each flight segment, flow control and the like in an available airspace of a flight; establishing a flight trajectory multi-target dynamic planning model by realizing minimum fuel consumption, shortest flight time and minimum height layer change times as targets; designing a solving algorithm of the flight trajectory multi-target dynamic planning model; and finally solving the model to form multiple strategies of flight trajectory multi-stage decision. According to the method of the invention, a technical basis is provided for air traffic control and air traffic flow management.

Description

technical field [0001] The invention belongs to the field of air traffic management, in particular to a multi-objective dynamic planning method for flight trajectory of an airliner applicable to air traffic control and air traffic flow management. Background technique [0002] Trajectory planning in air traffic management generally optimizes flight trajectories with certain objectives based on conditions such as airspace structure, aircraft performance, and flight restrictions. The main methods include trajectory planning based on airspace grids, trajectory planning based on restricted area geometry, and fixed-based Trajectory planning based on waypoints, trajectory planning based on standard entry and departure procedures, trajectory planning based on free flight, etc. Most of the existing research aims at shortening the voyage and flight time, reducing flight conflicts, etc., and rarely considers factors such as altitude changes and waiting in the air, and trajectory plann...
