Research On The Problem Of Outboard Storage Of Aircraft Carrier Hangar

With the delivery of the aircraft carrier "Shandong" to the PLA navy,China has officoally entered the era of dual aircraft carriers.But there is still a long way to go before the combat effectiveness can be formed.As carrier-based aircraft is the main source of aircraft carrier combat capability,the research of carrier-based aircraft is particularly important.Carrier-based aircraft scheduling technology is an important index to evaluate the evaluate the aircraft carrier combat capability.At present,the research on carried-based aircraft scheduling technology is mainly focused on the flight deck.While the aircraft carrier hanger is relatively narrow compared to the flight deck space,and carried-based aircrafts are spotted more closed,so it is difficult to control the time cost and safety problems only by manual command and scheduling.In this paper,through analyzing the aircraft carrier hanger environment and the operation flow of carrier-based aircraft outbound,the author foucses on how to apply the intelligent optimization algorithm to optimize the sequence of carrier-based aircraft outbound,to imporve the efficiency of carrier-based outbound operation.This paper first analyzes the domestic and foreign papers related to the Carrier-based aircraft scheduling,and finds that in the current published papers,foreign countries,especially the United States,has moew in-depth research in thos area.After the Liaoning was released in China,research on carrier-based aircraft started gradually.Secondly,the operation flow of carrier-based aircraft outbound is described,it is found that it is similar to the flexible flow shop scheduling problem,and This paper focuses on the analysis of the common algorithms related to job-shop scheduling.Then,the author chooses the appropriate modeling method to model the hanger environment and carrier-based aircraft,considering the small hanger environment and carrierbased aircraft spotting closely,uses the bidirectional RRT algorithm to complete the pathing planning between the starting point and ending point and the separation axis rgeorem to carry out collision detection in the path planning process,so as to prevent to collide with the other spotted carried-based aircrafts in the hanger.In chapter 3 to charter 5,three different cases of carrier-based aircraft outbound problem are studied.In chapter 3,the multi-aircraft outbound problem designated carrier-based aircraft is analyzed and modeled.With the goal of minimizing the total time of transport,the carrier-based aircraft outbound order is optimized bu using improved particle swarm optimization algorithm.In chapter 4,based on chapter 3,the the undesignated carrier-based aircraft outbound problem is studied.According to the outbound requirement,the Microhabitat genetic algorithm is applied to select the carrier-based aircraft spotted in the hangar,and the algorithm in chapter 3 is used to calculate the shortest outbound time of the selected carrierbased aircraft.In chapter 5,when a certain carrise-based aircraft leaves the hangar,there are many carrier-based aircraft in the hangar,and there is no safe path to the lift,so it is necessary to transport the nearby carrier-based aircraft to the flight deck.This phenomenon is called "inverted aircraft" problem.An optimal mathematical model is established for the "inverted aircraft" problem,with the aim of minimizing the total time of transport,and the solution is obtained by using Microhabitat genetic algorithm.Based on the Qt as the platform,with its good graphical interface display function,using the c++ language to different cases for different simulation,The simulation results are presented in a table.using the data from the table,the outbound schedule gantt chart intuitivly displays outbound order,to verify the feasibility of aircraft outbound scheduling theory...
