Abstract

The invention discloses an aircraft route optimization method based on meteorological grids. The method comprises the following steps: (1) establishing a multi-constraint route optimization model of an aircraft based on the meteorological grids; (2) designing an efficient air route rapid optimization strategy and algorithm coupled with meteorological grids; and (3) taking the severe weather as a no-fly zone constraint, carrying out threat modeling and quantification, and carrying out optimal airway design under a severe weather condition. According to the invention, the optimal route of the aircraft is designed based on the high-precision meteorological raster data, so that the flying ability of the aircraft and the adaptability to complex and changeable meteorological environments are improved.

Description

technical field [0001] The invention relates to an aircraft route optimization method, in particular to a weather grid-based aircraft route optimization method. Background technique [0002] When an aircraft flies in the atmosphere, it will be affected by meteorological conditions. Meteorological conditions mainly affect the flight characteristics of the aircraft through aerodynamics. Therefore, it is necessary to plan and optimize its route in real time according to the current and forecasted future weather conditions to ensure its flight efficiency. and security. The existing meteorological parameters used for route optimization have the problems of low precision, small range, and slow data refresh, which seriously affect the effect of route optimization. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a route optimization method based on meteorological grids with high precision and large range of meteorological pa...
