直升机驾驶舱眩光测控研究

Research on Glare Measurement and Control in Helicopter Cockpit

针对直升机驾驶舱眩光问题，提出了一种测控方法。用统一眩光指数评估直升机驾驶舱夜间眩光情况，用日光眩光概率评估白天眩光情况。以某直升机为例，运用光学软件SPEOS模拟实际光学环境，并从结果中测量提取光学参数，评估结果与实际情况相符，并针对该型机存在的问题进行优化。最后，以评估模型为出发点，提出了直升机驾驶舱眩光的可行控制策略，为降低眩光研究提供可行方向。

A measurement and control method to solve the glare problem in helicopter cockpit is proposed. The night glare in helicopter cockpit was evaluated by UGR, and day time glare was evaluated by DGP（ daylight glare probability）. Taking a helicopter as an example, the optical software SPEOS is used to simulate the actual optical environment, and the optical parameters are extracted from the results. The evaluation results are con- sistent with the actual situation, and the existing problems of the helicopter are optimized. Finally based on the evaluation model, a feasible control strategy is proposed to reduce the glare in helicopter cockpit.
