光环境模拟中的云雾闪电模拟系统设计

Design of cloud and lightning simulation system in light environment simulation

在正常天气环境下,民机驾驶员在驾驶舱内进行视觉作业(如观察判读仪表、显示器等)处在一个较为舒适的光环境中,但在恶劣天气环境下,驾驶舱内突然出现的强眩光源会造成飞行员视觉、生理以及空间方向感的损害,使飞行员的反应时间受到限制,直接威胁到飞行安全。在光环境模拟中的云雾闪电模拟系统设计,针对云层、闪电这两种自然现象的不同模拟指标,采用云雾模拟系统和闪电模拟系统分别在地面进行云雾闪电模拟,实现了在地面模拟恶劣天气环境,如雷暴雨、穿云层等,能为驾驶舱的光学集成设计、视觉工效设计、验证试验、人因工程研究等提供多功能、可复现的光学验证条件。

In normal weather conditions,civil aircraft pilots perform visual operations(such as observation and interpretation of instruments,monitors,etc.)in the cockpit in a relatively comfortable light environment,but in harsh weather conditions,the sudden appearance of strong glare sources in the cockpit will cause damage to the pilot's visual,physiology and spatial orientation,limit the pilot's response time,and directly threaten the flight safety.In the design of cloud and lightning simulation system in light environment simulation,aiming at the different simulation indicators of cloud and lightning,the cloud simulation and lightning simulation system are used to simulate cloud and lightning on the ground respectively,realizing the simulation of severe weather environment on the ground,such as thunderstorms,crossing the clouds etc.,which can provide multi-function and reproducible optical verification conditions for the optical integration design,visual ergonomic design,verification test,human engineering research of the cockpit.
