基于视觉仿真的飞机座舱风挡眩光分布影响研究

现代飞机座舱内照明灯具、综合显示器以及其他发光显示器件的大量应用，使得座舱内光学环境越来越复杂。不合理的照明和内饰设计，或者不合适的舱内空间布局，将会导致各种有害光的出现，影响飞行安全。采用视觉仿真方法，从操纵台控制显示装置的布置角度、布置位置等方面对其在前风挡形成的有害光进行分析，结果表明：针对大弧度曲面造型风挡，调整控制显示装置布置角度对有害光分布的影响有限，调整布置位置对有害光分布的影响显著，可以大大改善或避免眩光对飞行员的影响。

the effects of center pedestal Control Display Unit (CDU) on resultant windshield glare analyze

Cockpit interior lighting, integrated displays, and other light-emitting display units have been found increased application in the modern cockpit. As a result the optical environment within the cockpit becomes more complicated. Inappropriate lighting and furnishing design or cockpit spatial layout generates glare and affects flight safety. The effects of center pedestal control display unit (CDU) orientation and position changes on resultant windshield glare are analyzed. It is found that, for curved windshield, CDU orientation has limited influence on glare distribution while CDU position has a pronounced impact on glare distribution. Hence in CDU position changes are effective for alleviating or eliminating glare.
