Modern Fighter Simulation Architecture And Modeling

The 4th generation fighters are designed to have the ability of supersonic cruise. stealth and supermaneuverability which is based on the high-tech achievements of various fields including advanced aerodynamics, modern control theory and so on. in order to achieve the air superiority in modern air combats. While the weapon system is becoming more complicated, the requirement for life cycle upgrades and reduced initial development costs also becomes one of the design goals. Simulation, a technique to test the exiting or future system on the computer without the physical object, has been widely used in the fields of aeronautics and aerospace.The thesis describes the conception of the object-oriented modeling and integrated simulaton enviroment, and discusses the below topics:(1) Describe the reasonable structure of the modern fighter simulation system, and design the data transfer interface.(2) Discuss the modeling method of the key subsystem of future fighter system especially the aerodynamics and the control system in detail.(3) Construct the 3D model of the aircraft and scene, and verify the graphic simulation technique based on PC.(4) Study the technique on the simulation model validation and the verification, and verify the quaternion kinematic equations compared to the traditional kinematic equations.The study proves that the structure of the modern fighter simulation system is reasonable, and has built the solid base for the further study.
