面向网络的实时飞行模拟系统模型

Networked Real-Time Flight-Simulation System Model

为提高培养飞行员的效率和质量,节约费用,从整体上设计并实现了一种实时的、面向网络的飞行系统仿真模型。为了使其具有通用性及实时性,采用数据驱动方式,并通过使用稳定系数方式单独设计了一种适用的空气动力的数学模型。通过简单的配置用XML(extensib le M arkup Language)格式描述的配置文件,可以同时模拟各种类型的飞机飞行驾驶,为飞行员的飞行模拟训练提供了仿真平台,模型的建立方法可以为同类设计和研究提供借鉴。实践证明,本模型在通用性、实时性以及仿真度等方面基本符合要求,应用此模型实现了某种国产初级教练机的仪表飞行系统,并被应用于飞行员的仪表飞行训练中。测试结果表明,如果不加控制信号,飞机能保持平飞状态达30 s以上。

In order to improve the training efficiency and quality of the pilots and to save money, a networked real time flight-simulation system model is designed and implemented. In order to improve the capability of generality and real time, we adopted a complete data-driven technique and design an effective aerodynamic math model using stability coefficients. Through a simple configuration of the XML files, it can simulate various aircraft manipulations simultaneously and provide a flight simulation platform for training the pilots. The building method of the model can provide references for congeneric research and study. In practice, it satisfied the needs brought forward and has been used for implementing the instrument flight training system developed for the airforce. Eexperimental result showed, if freed from the control signals, it can keep flat flying about thirty seconds and it approaches the real flying very much.
