Embodiment Construction

[0050]The technical solutions of the present invention will be further described below in conjunction with the embodiments. In the embodiment, there are 2 Mi-28 armed helicopters flying. Helicopter 1 detects the position of the threat during the flight, and does not deal with the danger. Instead, it uploads the danger information to the blockchain, and helicopter 2 retrieves the information from the blockchain. Obtain threat information parameters and process them. There are three terrain threats at (55km, 55km), (15km, 25km), (10km, 15km); communication threats (55km, 55km), (10km, 50km), (15km, 7 at 25km), (30km, 25km), (10km, 15km), (40km, 15km) and (40km, 10km); the length of the track segment is 5km, the turning angle [-60, +60], the pitch angle [-30, +30], the range is 470 kilometers. The parameters of the artificial immune algorithm are: the maximum number of iterations is 5, the number of candidate route sets is 3, the number of track points is 12, and the minimum tra...

Abstract

The invention relates to a helicopter route planning method, the steps of which are: building a terrain threat avoidance model, calculating the flight route, constructing a random route set including a comprehensive coordinate (xy) sequence, updating the quantum phase, realizing the dynamic update of the route set, and constructing a communication Signal threat avoidance model TX, execute route evaluation fp, use B-Spline method and route optimization algorithm to improve the optimal initial route, and realize route flightability optimization. The present invention is the problem of route selection in consideration of voyage length, flight safety and aircraft performance. The results of the calculation example show that the real-time planning of the global optimal route can be realized by using the hybrid intelligent cluster algorithm in a complex environment. This method can provide effective flight services for helicopters and improve flight safety and reliability.

Description

technical field [0001] The invention belongs to the field of helicopter route planning, and relates to a method for planning an optimal flight route by using information such as helicopter performance and environmental threats, in particular to a helicopter route planning method. Background technique [0002] So far, domestic and foreign researches on route planning in complex environments are relatively preliminary, and a complete and systematic helicopter dynamic flight route planning model and method have not yet been formed. The dynamic route planning of helicopters in complex geographical environments has not been well resolved. How to apply the hybrid intelligent cluster algorithm to plan the flight route with the greatest safety performance, avoid dynamic threats and realize aviation safety rescue is an urgent problem to be solved. It has extremely important application value for both military and civilian use. Contents of the invention [0003] The purpose of the ...
