Airplane search and rescue method

Abstract

The present invention relates to an airplane search and rescue method. The method comprises the following steps: 1, calculating the optimal searching width W of the search and rescue according to the expected search success probability Q; 2, determining a search mode according to the relation of the optimal search width W and the minimum turning radius Rmin of an airplane; 3, calculating the coordinates of each turning point in a search area according to the optimal searching width obtained in the step 1, the search mode obtained in the step 2, the search boundary point obtained in the step 3 and turning reference points, wherein all the turning points are located below one of the turning reference points, namely the turning points and the turning reference points have the longitude; and 4, performing flight search and rescue according to the points of penetration and the turning points. The airplane search and rescue method performs search and rescue and flight route planning of a search area in a grid-shaped search mode to clear the key navigation parameters such as the coordinates of the point of penetration of the flight route and the coordinates of the turning points so as to make a feasible flight route for an airplane and reduce the areas of repeating search and omission search.

Description

technical field [0001] The invention relates to the field of aircraft flight route design, in particular to an aircraft search and rescue method. Background technique [0002] With the vigorous development of my country's marine transportation industry, water transportation is becoming increasingly busy. At the same time, due to the large volume of maritime transportation and low cost, maritime transportation has gradually become the main mode of my country's foreign trade. However, due to the complexity and variability of the marine environment, the number of maritime accidents The occurrence is more and more frequent, leading to increasingly serious maritime safety problems in our country, which has aroused extensive attention from the state and society to maritime traffic safety. [0003] For the research on maritime search and rescue, most of the current domestic research focuses on the determination of the search area or the optimal selection of rescue ships. Although re...

Problems solved by technology

Reflected in actual work, searchers and commanders often make two mistakes: the first is to roughly determine the search route by means of on-site estimation, and the route determined based on experience is often too random and easy to Re-search and missed searches occur; another mistake is that the established route cannot effectively display the search capability without considering the characteristics of the aircraft itself and the on-board search equipment

If these data are used to formulate search plans, many search targets will be missed when searching certain areas, so that the entire search activity will be inefficient or even ineffective
