The real-time flight simulation system based on computer environment is constructed. Firstly, the nonlinear dynamic equa-tion and the mathematical model of landing gear are established; designed the engine, aerodynamic coefficients, wind and atmospheric environment model. Then the function of each module is programmed under the environment of simulink. An effective method of data pre-processing and function generation is proposed to ensure the validity of the real-time simulation. Finally, the experiments of glid-ing, takeoff, cruising and landing based on the integrity of the simulation model are simulated. The experiment results prove that the model is valid and can reflect the dynamic characteristic of actual aircraft. The model provides a valid simulation platform for the re-search of automatic flight simulator in flight system.
