Flight Simulator

The technology of system simulate is based on the theory of control, the theory of analogy, the technology of information process and the technology of calculate; It is an all-around technology which does research on the real or fictitious things. The technology of system has high security and great economics, so it was applied by many fields such as aeronautics and astronautics. Flight simulator is a typical real-time simulant system which includes real things,and it is one application instance of the technology of virtual real.This article introduces the design and implement of flight simulator based on DSP which contains five parts. The first part establishs the math model of flight simulator which contains the model of aerodynamics and flight mechanics,the model of standard atmosphere and wind model;The second part introdces primarily the arithmetic of numeric integral which is very important to dyanmic system simulant. The third part introduces the design of hard interface circuit and program.The fourth part introduces the data flow graph of the flight simulator software and Gunge-Kutta integral arithmetic.the finall part introduces the design of serial port communication software,it contains communication protocol,the process of upper machine and lower machine communication and the programing of serial port communication by VC++.
