基于飞行工程模拟器的视景系统有效性研究

介绍了自主研制的飞行工程模拟器视景系统,并以该系统为研究对象讨论了影响视景系统有效性的关键因素。对于大型场景,提出采用分块调度和实时修正的动态数据管理策略解决了飞行仿真中有限的硬件处理能力与不断增长的大地形仿真之间的矛盾。试验测试证明,驾驶员能够根据OTW场景内容准确的判断仿真飞机姿态、机场位置、地面和空中目标等,从而高效完成相关试验科目和飞行任务。

Research on Effectiveness of Visual System Based on Flight Engineering Simulator

Visual system-based flight engineering simulator developed was introduced. Regarding the system as a research object, some key cueing elements affecting effectiveness of visual system were discussed. For mass dataset terrain, the contradiction between the finite process ability of hardware and the increasing mass dataset in flight simulation was solved by adopting to schedule them in blocks and revise them real time. Testing has proved that the pilot can judge aircraft attitude, position of airfield, and objects both on the ground and in the air, and then test subjects and flight tasks can be completed effectively.
