Abstract

本发明公开了一种运输机货舱大门低振噪比的控制系统，该项目属航空技术领域，包括电子、机械学科，还涉及到控制原理技术。本发明通过对货舱大门驱动装置进行配置，提出货舱大门控制技术使用过程中出现的问题进行优化设计，使飞机满足复杂环境下低振噪比的使用要求。

Description

一种运输机货舱大门低振噪比的控制系统
技术领域
本发明属于中型中程运输机舱门驱动技术，涉及一种飞机货舱大门控制技术。
背景技术
随着的运输装备不断强化，运输机除用来载运重型装备和人员外，还必须具备空投、空降功能。货舱大门是由电磁阀、液压锁、单向节流阀向作动筒开起腔供压，将货舱货舱大门打开。而货舱大门的关闭是经液压锁，向作动筒关闭腔供压，将货舱大门关闭的。在关闭货舱大门时，由于货舱大门自身的重量比较大，使得系统的回油压力达到安全阀入口压力的上限，造成货舱大门在关门初期安全阀频繁开启、关闭，使液压系统出现共振现象，导致液压系统啸叫。这种共振及啸叫现象，严重影响飞机的飞行安全。
发明内容
(一)发明目的：本发明克服了现有技术中的不足，用简单的控制方式提供了一种在进行运输装备或人员空投空降时，货舱大门能可靠地开关的技术。
(二)技术方案：一种运输机货舱大门低振噪比的控制系统，在现有货舱大门液压操纵系统的基础上，在液压锁和货舱大门作动筒之间的关门管路上增加延迟活门，货舱大门在关闭过程中，液压油在延迟活门作用下，先去开货舱大门上位锁，开锁后液压油再去货舱大门作动筒关闭腔进行关门。
(三)有益效果
与现有技术相比，本发明的有益效果(优点)是：本发明在设计上结构简单,涉及面小，可靠性较高，实现了在空投空降过程中将货舱大门可靠地进行开关运行。
附图说明
图1为本发明控制结构示意图；
其中：1.节流管嘴,2.Y8C-5808-800安全阀,3.货舱大门上位锁,4.液压锁,5.16A4-1436-11单向节流阀,6.Y8-5809-70延迟活门,7.货舱大门作动筒。
具体实施方式
下面结合附图与具体实施方式对本发明作进一步详细描述：
货舱大门液压操纵系统由货桥锁机构液压系统、货桥开关液压系统、货舱货舱大门开关液压系统组成。货桥的开启有空降、空投和地面三个位置，空投时货桥开到水平线下与水平线夹角4°20′，空降时货桥开到与水平线平齐。
货舱大门技术上采取了余度设计，货舱大门有电气开关自动控制和手动阀控制两种形式。使用电气开关控制形式时可自动完成全套操纵程序，电气开关自动控制配置了三种操纵方式：
①在正常情况下由右系统供压；
②应急操纵由左系统供压；
③用手摇泵—电动泵系统也可以应急操纵货舱大门。
使用手动阀控制货舱大门时遵循一定顺序进行，不能颠倒，开货舱大门顺序：开货舱大门—关货桥—开货桥锁—开货桥；关货舱大门顺序：开货桥锁—关货桥—货桥上锁—关货舱大门。
货舱大门液压系统内安全活门Y8C-5808-800在货舱大门开关过程中震动和啸叫是由于在关货舱大门的过程中，系统回油腔压力较高，使得安全活门Y8C-5808-800频繁打开，流量脉动造成货舱大门液压系统内压力脉动幅值过大、频率过高造成的。为解决此问题采取的措施：
1)增大关闭货舱大门时系统的回油流量：将飞机货舱大门液压系统中单向节流阀
16A4-1436-9的节流参数：压差10MPa时流量为4.8L/min调整为流量6L/min，经对照标准，采用16A4-1436-11单向节流阀。
2)减少关闭货舱大门时系统回油对安全阀入口瞬时冲击压力：在液压锁和货舱大门作动筒之间的关门管路上增加延迟活门Y8-5809-70，货舱大门在关闭过程中液压油在延迟活门作用下，先去开货舱大门上位锁，开锁后液压油再去货舱大门作动筒关闭腔进行关门。
经过以上解决措施，使货舱大门在收放过程中液压系统流量得到改变，参数匹配比较合理，避免了液压系统共振现象。并且货舱大门液压系统的开关门时间无变化。
采用16A4-1436-11单向节流阀，以及在关门腔增加延迟活门Y8-5809-70的措施来解决货舱大门液压系统关闭时啸叫的故障，新增的附件单向节流阀16A4-1436-11为标准件，延迟活门Y8-5809-70为现有装机产品，改装时可直接选用。并且飞机上有合适的安装空间。并且在多架机上进行地面和飞行试验验证，均表明啸叫现象消失，系统工作正常，收放时间符合技术要求，达到了运输机货舱大门低振噪比优化的目的。
