交互式飞行视景仿真系统的设计与实现

Design and Realization of Flight Scene Simulation System

基于六自由度运动模型,提出了Vega环境中飞行运动的数学表示及其C++语言描述方法,构建了通用的基于C++/Vega的交互式飞行视景仿真系统的驱动程序流程和模块化功能结构,并基于MFC构架利用Vega的实时仿真驱动开发了交互式的实时飞行视景仿真系统。该系统可与控制主机、光电跟踪设备一起形成控制闭环,模拟飞机对运动目标的跟踪过程,并将相应的飞行参数以仪表的显示方式输出,辅助用户测试和评估光电跟踪设备的性能。

Based on 6-DOF motion model, the mathematic express and its C＋＋ language description of flight process in Vega were described. A general driving process of real time flight simulation in C＋＋/Vega and a general modularized functional structure of Interactive Real-time Flight Scene Simulation System （IRFSSS） were established, and therefore an IRFSSS was developed by means of utilizing real-time simulation driver of Vega based on MFC frame. The IRFSSS with a control computer and photoelectric track equipment could form a control closed loop to simulate the instance of airplane tracking moving targets. Correlative flight data was output in instrument display to assist user testing and evaluating performance of the photoelectric track equipment.
