Research On Key Techniques Of UAV Two-Three Demensional Cooperative Flight Simulation

Unmanned aerial vehicles take the leading role of winning the air supremacy in the present and future battlefield,whose importance is self-evident.But the process of its own development and production is rather giant.Besides,the cost of the latter part is considerably huge.Computer simulation technology possesses the characteristics of relatively low cost,high simulation and being reusable,which provides a better basis to solve the actual production and life problems.The actual production and application costs can be greatly decreased by simulation that is more widely used especially in the military field of technical training to the relevant personnel.This paper chooses to study simulated flight of UAV(unmanned aerial vehicles)and find out that the problem of insufficient map data in the simulation software as well as the software adaptability in different environments.The quality of maps in the platform is a key factor.Maps can display the exact location of UAV in real time in the air.The two-dimension maps can programme the flight direction and routes of UAV on the whole.The three-dimension maps can grasp the details of the flight parameters of the current aircrafts and the basic geomorphic conditions of the locations of the aircrafts,which plays a key role in the real-time control of the aircrafts and dealing with emergencies.However,in most of the simulation platforms,there are only the two-dimension maps or only the three-dimension maps,or a small part of maps which is both two dimensional and three dimensional but can not achieve the synergistic operation.Combined my participation in the mentoring project and learning experience,this paper mainly studies as follows.(1)Making use of Qt framework to build the two and three dimensional platforms.As to the two-dimension maps,the independently developed software platform is used and I add some of the functions on this basis.Concerning the three-dimension platforms,the foreign OSG is used and by downloading the vector data,terrain and cultural data,elevation data as well as loading these to the three-dimension maps,the map information is completed.(2)To study the communication between the process and design the implementation programs.Targeting at the scenarios of single machine with single process,singlemachine with multi process,multi machines with single process,design the corresponding communication modes.(3)The design and implementation of simulation applications.Select the flight paths of the unmanned aerial vehicle as the entry point and use the communication modes of the second step to realize the two and three dimensional cooperative flight simulation,which successfully solves the problem of two and three dimensional maps' data linkage and intercommunication in multi-scenes.(4)Through the design,testing and modification of the entire software,the design requirements are basically reached,achieving the purpose of two and three dimensional collaborative simulation.
