飞机铁鸟舵面加载存在的问题及其解决方法

Problems Existing in the Loading of Aircraft Iron Bird Rudder Surface and their Solutions

由于铁鸟空间狭小,舵面收放独立于加载系统,加载作动筒的行程主要由舵面收放空间运动引起,舵面中立位置存在初始载荷,因而,铁鸟舵面加载系统研制和加载调试普遍存在干涉、跟随困难、安全隐患、加载精度低等问题。为解决上述问题,本文提出了加载机构无干涉设计方法、加载-跟随液压保护模块、加载安全调试方法和铁鸟舵面加载无突变解析控制法。这些方法在某大型民机铁鸟舵面加载系统中成功应用,缩短了加载系统研制集成和调试周期,提升了加载精度和调试安全。

Because the space of the iron bird is narrow,the rudder surface deflection motion is independent of the loading system,and the stroke length of the loading actuator is mainly caused by the movement of the rudder surface,and the initial load exists in the neutral position of the rudder surface,the following problems prevail in the development and loading debugging of iron bird rudder surface loading system,such as interference,follow difficulty,hidden danger,low loading precision and so on.In order to solve the above problems,this paper presents a non-interference design method for loading mechanism,a load-following hydraulic protection module,a loading safety debugging method and a no-mutation analytical control method for iron bird rudder surface loading.These methods have been successfully applied in the loading system of a large civil aircraft,which has saved the development and debugging cycle of the loading system,and improved the loading precision and debugging safety.
