Research On Virtual Scene Simulation For Aircraft Landing

Because of the impact conditions of Aircraft landing is complex, and aircraft landing isrelated to the aircraft carrier’s marine operations. So the calculation of landing movementsand position is a very important research value. China’s aircraft carriers industry is in itsinfancy, and interrelated research is lack, it will be laborious process if doing the research inthe traditional way. But researchers could make the research in-dept when using computertechnology to simulate the landing process.The simulation of Aircraft landing is one aspect of shipping simulation, it uses visualreality technology to simulate the whole aircraft landing process in the way of visualsimulation. If researchers make the new computer technology in the use of aircraft landingresearch, it could help them shorten the research cycle and save money as an important meansof supporting the experimentations.The paper analyzes in the two ways which are aircraft landing movements and positions,then simulate the process with visual simulation. The paper uses C++software to calculate thelanding movement equation and landing position equation, and simulates it with MFC classlibrary. And the calculation would promote the aircraft landing evaluation and prediction. Thepaper includes followings:First, the paper conducts a reasonable assumption to the aircraft carrier and the aircraft,according to Newton’s classical mechanics equation to establish a six degrees of freedommathematical model in the process of aircraft landing, and the model would be used as thetheoretical basis of simulation calculation which provides real-time date of movement. In thecalculation, the paper uses separation to analyze and discuss the various forces in the processof landing, and then obtains the six degrees of freedom mathematical model with the othernecessary factors.Second, according to the necessary conditions of aircraft landing, obtain the distributionof landing points by the law of motion which aircraft carrier in a particular sea state. Andgetting the probability of carrier-borne aircraft landing and going around, provide a block ofdate to support it.Then, the paper completes with Vega and Creator software to build the virtual scene andthe model work, the processes above are described in detail. Meanwhile it focuses on the use of main modules and the building process of ADF files.Finally, the paper investigates the interface of the simulation by the MFC with C++software, and analyzes the operation of mechanism by the investigation. Meanwhile, thepaper describes the design of interface and functions of keyboard, then visualizes thesimulation to verify its feasibility.
