Research On Simulation System Prototype Of Aircraft Crash On The Sea

Based on the theory of system simulation, this thesis aims to build an aircraft simulation system, which is used in computer simulation training, having important practical meaning. It provides vivid scene effect for the simulation training by doing the research the state and action of aircraft and airman, in favor of establishing the rescue projects.Firstly, some basic theories of system simulation, including the rescue system frame and the function of the aircraft crash sub-system are introduced.Secondly, in order to research the aircraft crash simulation system model, this thesis is divided to three parts: aircraft flight simulation model; aircraft crash simulation model; aircraft corresponding system. In the first part, this thesis adopts scene emulation mode to establish the aircraft flight model, including Six Dimensions Hover flight model which describes aircraft flight situation and scene protract by the three aspect X_eY_eZ_e flight and turn, resolving the problems which include getting scheduled flight; longitude and latitude arithmetic in electronic map and getting weather information. The second part is done from four angles: crash happening model, the reason of crash model, crash simulation model, pending rescue model. Combing the exterior factor and interior factor, this thesis excerpts R=R( t) to establish the crash happening model, and endows the factor coefficient after the exterior factor and interior factor are confirmed. In the pending rescue model, this thesis does the research from three aspects: the influenced facts, the crash grade and the output model of aircraft pending rescue. In the third part, Socket corresponding technology, audio and video frequency coding technology, audio and video frequency data net transfer technology are used to establish corresponding system model, which having three functions: regular information release, alarm, video frequency expander. Finally, the conclusions of this paper is done, it's summed up the research results of Aircraft Crash on the Sea system, and the need to improve the existing system of a number of prospects.
