摘要
民用飞机座舱(驾驶舱和客舱)是机组、乘客工作和生活的空间,作为一个密闭的空间,需要有适宜的空气流场,为乘员提供舒适的温度和充足的新鲜空气。当驾驶舱产生烟雾时,排烟通道应该能够快速地将烟雾排除。主要通过数值模拟获得排气通道空气流场,从空气流场的角度进行排烟分析。对比了两种不同的座舱压力调节系统排气活门的布置方案,为系统设计决策提供依据。
Aircraft cabin（including cockpit and passenger cabin） is working and living space of crew and passengers. As a closed room,the cabin needs an appropriate flow field to provide comfortable temperature and adequate fresh air for passengers. When smoke occurs in the cockpit,smoke remove tunnel shall discharge the smoke out of the aircraft rapidly. This article mainly analyzes the smoke remove issue through numerical simulation of smoke discharge tunnel flow field. It compares two different types of Cabin Pressure Control System outflow valve layout and provides the basis for system design.
