Method for optimizing launching time sequence of coordinated attack of aircraft based on time constraint library

Abstract

The invention discloses a method for optimizing a launching time sequence of a coordinated attack of an aircraft based on a time constraint library. The method is capable of accurately solving comprehensive problems on a launching time sequence plan in case of collision and a simultaneous attack of the aircraft on an object which are possibly exist in a flying process, and comprises the following steps of: step I, processing flight path data through a flight path cross-checking method; establishing a flight path cross-checking problem depending on the flight path data which is set, namely, judging whether any two flight path curves are crossed or are less than the minimal distance constraint at the same moment under the preset minimal distance constraint; step II, establishing a launching time sequence constraint library based on the preset flight path, wherein the constraint base describes possibility of path crossing of any two aircraft while launching at one time difference; and step III, on the basis of the launching time sequence constraint library which is obtained from the step II, extracting and simplifying the launching time sequence constraint, and establishing a launching time sequence plan model based on a purpose of avoiding crossing of the flight path.

Description

technical field [0001] The invention can be widely used in various fields of collision avoidance and cooperative attack target launch timing planning, and relates to an aircraft coordinated attack launch timing optimization method based on a time constraint library. Background technique [0002] In the process of multi-aircraft attacking the target cooperatively, due to the large number of aircraft, there may be situations where one’s own aircraft collides in the air or is too close. In addition, the time to reach the target is controlled by the launch sequence so that it can be as close as possible to the target. Attack the target at the same time, which will improve the aircraft's defense penetration capability and damage effect, and improve efficiency. [0003] Collision inspection and launch timing planning during aircraft flight are problems that are often encountered in engineering applications. There is no better solution in the published literature. The main disadv...

AI Technical Summary

Problems solved by technology

The main disadvantages are 1) the aircraft usually fly at a high speed and the flight distance is long. Due to the limitation of launch preparation time and computer computing power, it is impossible to conduct point-by-point inspection of the flight trajectory in actual engineering; 2) after the aircraft collision inspection, There is no good planning criterion for aircraft that may launch collisions, and it is impossible to complete launch timing planning in a short time; 3) An efficient solution has not been proposed for the comprehensive problem of aircraft attacking targets at the same time and avoiding collisions during flight, making it Can be quickly applied in engineering
