摘要
为了精确调节飞机座舱压力,应用CFD软件对排气活门的二维流场进行了计算,得到了特定高度和开度下舱内压力分布以及活门最大流量所对应的飞行高度。计算还给出了不同飞行高度、不同开度下的活门流量,从而绘制出了排气活门的流量特性曲线,获得了排气活门的基本流量特性规律。
In order to accurately regulate the cabin pressure in aircraft, the outflow valve flux characteris- tics should be analyzed firstly. By using CFD software, the 2D simulations were carried out for pressure field and the velocity field of the valve. The fluxes in different flight altitudes and different valve angles are obtained, and the flux characteristic curves are plotted out.
