Abstract
The modeling of aircraft motion is very important for aircraft flight performance evaluation, aero-engine design and air-combat modeling and simulation. However, the flight of aircraft is a complex process, and its flight capability is affected by many factors. The existing modeling process is generally based on analytic methods or energy methods, which leads to complex modeling process or lower model accuracy. For this reason, we deduced the coordinate transformation matrix, and on this basis, established a differential equation of aircraft motion with the earth fixed axis system, and finally built an aircraft motion model based on the numerical integration method. Experiments show that the method is simple and high-precision, and can meet the requirements of rapid modeling of warfare simulation.
