虚拟技术在模拟飞行训练中的应用

Application of virtual technology in simulated flight training

培养一名飞行员的花费是很大的,如果每次的训练都使用真实的飞机进行作业,不仅其成本高昂而且充满了风险。为了解决该问题,介绍了一种采用飞机动力学、空气动力学和视点变换技术制成的仿真系统,它的优点是其可视的、三维实体的与物理原型无异,使得训练人员具有身临其境的感觉。该系统结构合理而且安全可靠,采用的运动模型和仿真算法满足了系统的实时性和精确度要求,图像显示效果逼真,适合广泛地应用于飞行模拟训练当中。

It is weel known that it is very costly to cultivate a pilot, if using the real aircraft in the operations every time, not only its cost is high but also is full of risks. In order to solve the problem, a kind of the simulation system combined with air- craft dynamics, air dynamics and perspective transformation technology is introduced in this paper. It has the advantages of the visualization and 3-D entity same as the physical prototype, and can make the training personnel has the feeling on the real scene. Testing with the whole system indicates that the simulation system is reasonable and reliable, the mathematic model and simulation algorithm also completely satisfy the system requirements of real-time nature and accuracy, the image display is life- like. It is suitable for widely underwent of simulation training.
