摘要

摘要:
飞机座舱进气流量冲击情况下，气动式座舱压力调节系统(PCPCS)可能由于动态调节速度不足而导致座舱压力尖峰，进而出现“压耳”问题。基于此，对PCPCS的工作原理开展分析，指出小腔可能对排气活门的快速运动产生阻碍。建立PCPCS的动力学模型，描述排气活门中控制腔（A腔）和小腔（B腔）的工作状态；开展PCPCS在座舱进气流量冲击下的动态工作仿真，定量展示排气活门的动态工作特征和活门芯的受力变化；讨论小腔定径孔直径、小腔顶部直径、小膜片直径对排气活门应对座舱进气流量冲击的影响。仿真结果表明：适当增大小腔定径孔直径有助于提升排气活门响应速度，小腔顶部直径对排气活门运动速度没有显著影响，减小小膜片直径对排气活门响应速度的提升较为显著。

Abstract:
Under aircraft cabin inflow impact, the inadequate dynamic regulation speed of the pneumatic cabin pressure control system (PCPCS) may lead to a cabin pressure spike, causing “barotrauma”. Therefore, the working principle of the PCPCS was analyzed, and it was pointed out that the balance chamber may hinder the rapid movement of the outflow valve. A dynamic model of the PCPCS was established. The working states of the control chamber (A chamber) and the balance chamber (B chamber) in the outflow valve were described. The dynamic simulation of the PCPCS under cabin inflow impact was carried out. The dynamic working characteristics of the outflow valve and the force changes of the poppet were quantitatively displayed. The effects of the metering hole diameter of the balance chamber, the top diameter of the balance chamber, and the diameter of the balance diaphragm on the outflow valve’s response to cabin inflow impact were discussed. The simulation results show that appropriately increasing the metering hole size of the balance chamber can help to improve the response speed of the valve; the top diameter of the balance chamber has no significant effect on the movement speed of the outflow valve, and reducing the area of the balance diaphragm improves the response speed of the outflow valve significantly.
