Design And Realisation Of Real-time Flight Simulation System For Unmanned Aerial Vehicle

The article mainly introduces how to build the flight simulation system which can reflect the flight of unmanned aerial vehicle, and analyses requirements and methods of the medeling and the structure of medels in detail. The flight simulation accomplishes the modeling specifically which is based on some unmanned aerial vehicle model and developing the flight simulation system for unmanned aerial vehicle. The flight performance of unmanned aerial vehicle is analysed and evaluated based on the data which is recorded by flight simulation system.The main research contents are as follows:1. Object-oriented design methodology for flight simulation system is discusses, and structure of all models is builded for providing the process frame of the modeling entirely. The partition and function of models is also analysed.2. Modeling for flight simulation system. It mainly contains aerodynamic model, Flight dynamic model, power system model, atmosphere environment model, and so on3. Realisation of Flight simulation system. Technologies such as DirectX and object-oriented programming are used to realize visual three-dimensional flight simulation system based on personal computer. The system can display the change of position and track for unmanned aerial vehicle directly by means of human-computer interaction. Flight simulation data can be also recorded.4. Based on the data which is recorded by flight simulation system, we can analysis and evaluate the operation and stable performance of unmanned aerial vehicle and the change of flight performance in the process of ejection take-off.
