Research On Object-oriented Kinematic Modeling Technology Of Flight Simulation

This article mainly discusses a software frame of flight dynamic simulation which is based object-oriented design methodology. Some algorithmic methods used on solving the flight dynamic deferential equations and net performance of real-time distributed interactive system were analyzed. The work is carried out as following aspects.1. The theory and design method of the flight dynamic simulation which is based object-oriented design methodology technology is analyzed. The mathematical character of the simulator model was introduced, including dynamic equations, aerodynamic analysis, engine model, standard atmosphere model, etc.2. Mathematic method of the flight dynamic simulation is discussed, include flight dynamics model,motor model, act.3. Net performance of real-time distributed interactive system and the solution of net problems are discussed.4. The whole flight progress was simulated in real time with fixed step. The result of simulation shows that the model can reflect the flight character of the airplane modeled.5. The model contains the hardware return route as the core computation model participation the real-time simulation, has established the flight simulator preliminary frame.The flight dynamic simulation system has a great value in flight simulator. Building software frame which is based object-oriented technology, multi-platform, model size adjustable is mentioned in this paper. The model used in actual flight simulator interactive with display system, 6-DOF motion platform and tutor, completed the initial flight simulator framework.
