摘要
针对飞行模拟机视景系统助航灯光模块,提出了基于光点的可变颜色灯光仿真实现方法,对精密进近航道指示器进行模拟;深入分析了仿真平台的帧循环机制,完成了仿真坐标轴系与观察坐标轴系之间的转换,进而提出了采用位置补偿降低该机制带来的时间滞后。将其应用于飞行仿真实验平台,在实时性和逼真程度上,取得了预期的效果。
Considering the navigation lighting in vision system of flight simulator,a simulation method was proposed for lights with changeable color based on lighting points,which was used for simulating the Precision Approach Path Indicator（PAPI）.The frame circulation mechanism of simulation platform was analyzed,and the transform between simulation coordinate system and observer coordinate system was completed.Then position compensation was used to reduce the time lag caused by the mechanism.The method was applied in flight simulation experiment platform,and the expected result was obtained in real-time performance and fidelity.
