摘　　要：为缩短训练飞行员的周期,提高训练飞行员的质量,设计并实现了一种仪表飞行仿真系统。对系统中使用的各种技术进行了深入的研究,包括应用系数构造法实现空气动力学模型,采用基于组件的方式实现控制系统模型部分,应用树形结构组织管理各种数据以及使用XML(extensib le M arkup Language)语言定义配置文件等。在控制系统部分还给出应用基本控制组件实现PID(Proportional Integral Derivative)反馈控制器。这种基于组件的方式有效地提高了控制系统的灵活性及可扩展性。该仪表飞行仿真系统已应用到国产某型号飞机飞行员训练中,如果不加控制信号,可保持平飞状态30 s左右,非常接近实际飞行状态。实践证明,该系统在实时性和仿真度等方面均符合需求。In order to improve the efficiency and quality and shorten the pilot training period, a networked real time flight simulation system is designed and implemented. In this paper, we make a deep research about the methods used, including how to implement the aerodynamic model using coefficient buildup method, how to realize the control system based on components and how to manage all kinds of parameters using the tree like structure and define the configuration files using the XML （extensible Markup Language）. In control system, we also tip how to realize the PID （Proportional Iintegral Derivative） feedback controller employing the basic control components. This way of based on the components improve the flexibility and expansibility of the control system effectively. The implementing methods of the model can provide references for congeneric research and study. In practice, it is satisfied the needs brought forward and has been used for implementing the instrument flight training system developed for the airforce. If freed from the control signals, it can keep flat flying about thirty seconds and it approaches the real flying very much. We show the experiment result at last.
