运输机尾舱门收放液压控制系统的改进设计

Improved Design of Hydraulic Control System for Retraction of Aft Cabin Door in Transport Aircraft

针对现有运输机尾舱门收放液压控制系统需要复杂的逻辑控制及应急打开和关闭时间长问题,改进设计了一种通过系统压力调节能自动控制的液压系统,该系统除能实现舱门打开角度随地形变化的功能,还能实现快速应急功能。

In view of the complicated logic control required by the hydraulic control system for retracting and releasing the aft cabin door of the existing transportation aircraft and the long emergency opening and closing time, design of a hydraulic system that can be automatically controlled by system pressure regulation is improved, this system can not only realize the function that the opening angle of the cabin door changes with the terrain, but also realize the function of quick emergency.
