七、部件原理

1. General

The passenger door damper actuator installed on the passenger doors of the AIRBUS aircraft is intended for:

– slowing down the door at the end of its travel,

– ensuring door opening in all conditions.

It operates as a damper when opening or shutting the door under normal condition, and as an actuator when opening of the door is made impossible due to an external event.

1. 概述

安装在空客飞机乘客门上的乘客门阻尼作动器，其作用是：

– 在舱门行程结束时减缓其运动速度，

– 确保舱门在任何情况下都能打开。

在正常情况下，该装置在舱门开启或关闭时作为阻尼器工作；当因外部事件导致舱门无法开启时，则作为作动器工作。

2.Description and operation (Refer to Figure 1)

描述与工作原理（参见图1）

A. Actuator Body and Piston

The actuator body includes a clevis to attach it on door arm and bosses on which the pneumatic assembly is secured. Three vent holes in the body allow to shut the door after an emergency opening. The piston includes a ball end for attachment to door arm. The two chambers containing the hydraulic damping fluid are installed on main piston.

A. 作动筒壳体与活塞

作动筒壳体包括用于连接舱门臂的U型夹以及用于固定气动组件的凸台。壳体上设有三个通气孔，可在紧急开启后协助舱门关闭。活塞端部设有球铰接头，用于与舱门臂连接。两个容纳液压阻尼液体的腔室安装在主活塞上。

B. Damping system

Damping systems installed on main piston, slow down it on stroke end on opening or shutting of the door. The force of the impact on the fuselage is by this means, limited to an acceptable level. This damping action is produced by throttling of an hydraulic fluid. The damping in the door opening direction is a two stages damping action depending on the force of arrival of the hydraulic fluid in the damping chamber. In the door closing direction the force remains constant.

B. 阻尼系统

安装于主活塞上的阻尼系统可在舱门开启或关闭行程末端时减缓活塞的运动速度。通过这种方式，舱门对机身结构的冲击力被限制在可接受的范围内。阻尼作用通过液压液体的节流效应实现。舱门开启方向的阻尼为两级阻尼作用，其大小取决于阻尼腔中液压液体的冲击力；而在舱门关闭方向，阻尼力保持恒定。

C. Percussion Mechanism and Accumulator Assembly.

This unit allows to open the door when the manual opening is made impossible by a too high antagonistic force. When the door is opened in emergency condition by the flight personnel using the door opening handle a hammer comes to strike a puncher which perforates a diaphragm. This allows the nitrogen contained in a bottle to enter the rear chamber of the actuator which is then energized and opens the door. The pneumatic assembly also includes a valve to fill the bottle and a pressure gauge to ensure the nitrogen pressure remains correct. A safety device permits to set the actuator in armed or disarmed position with the red flagged pin. A shear pin prevents the inadvertent percussion due to vibrations. It must be replaced after each emergency opening.

C. 冲击机构与蓄压瓶组件

该组件用于在人工开启因反向作用力过大而无法操作时，实现舱门的应急开启。当飞行机组人员使用舱门开启手柄在紧急情况下开启舱门时，一个冲击锤会撞击冲头，从而刺破膜片。这使得储气瓶内的氮气进入作动筒的后腔，作动筒随即被驱动并打开舱门。气动组件还包括用于给储气瓶充气的充气阀，以及用于监控氮气压力是否正常的压力表。一个带有红色标志销的安全装置可将作动筒设置为待命或解除待命状态。一个剪切销用于防止因振动导致的意外冲击。每次紧急开启后，必须更换该剪切销。

八、工作参数

九、在飞机系统中的功能及其互联

1 . General

The doors are installed in the aircraft to give you access to the different compartments. Each door has a special function. There are:

– doors used as an entrance and an exit for the passengers and the crew,

– doors which are used for the loading and unloading of cargo and baggage,

– doors which are used for maintenance,

– some internal doors,

– miscellaneous doors.

You can operate the doors mechanically or hydraulically. All external doors are in line with the fuselage when they are closed. The aircraft has a Doors and Escape Slides Control System (DSCS) which monitors the position of some of the doors. Mechanical indicators are also installed on some doors. They show the CLOSED/LOCKED or UNLOCKED position of the related door.

1. 概述

飞机上的舱门用于进入各个舱室。每个舱门都有特定的功能，包括：

– 供乘客与机组人员进出的舱门；

– 用于货物与行李装卸的舱门；

– 用于维护检查的舱门；

– 部分内部舱门；

– 其他舱门。

舱门可采用机械或液压方式操作。所有外部舱门在关闭时均与机身外形齐平。飞机配备有门与逃生滑梯控制系统（DSCS），用于监控部分舱门的位置状态。部分舱门还安装有机械式指示器，显示相应舱门的“关闭/锁定”或“未锁定”状态。

A. Passenger/Crew Doors

The aircraft has six passenger/crew doors, three on each side of the cabin. These doors are called:

– FWD passenger/crew doors (door 1L/Z831 and door 1R/Z841),

– MID passenger/crew doors (door 2L/Z832 and door 2R/Z842),

– AFT passenger/crew doors (door 4L/Z833 and door 4R/Z843).

They are used as entrance and exit doors for the passengers and the crew. The passenger/crew doors are plug-type doors which open out and parallel to the fuselage. You can operate them from the inside and the outside of the aircraft. Each passenger/crew door has an evacuation facility which is kept in a container in the lower part of the door.

A. 旅客/机组舱门

飞机共有六扇旅客/机组舱门，机身左右两侧各三扇。这些舱门分别称为：

– 前旅客/机组舱门（1L/Z831 与 1R/Z841 门）

4 . Component Description

All of the passenger/crew doors have the same structure and mechanisms. The passenger/crew doors on the right of the fuselage are a mirror-image of those on the left. The geometry of the FWD passenger/crew doors is different from that of the MID and the AFT passenger/crew doors (which have the same geometry).

The passenger/crew doors are of a fail-safe plug-type design. They open out and parallel to the fuselage. An emergency escape facility is kept in a container which is attached to the lower part of each passenger/crew door.

4. 部件说明

所有乘客/机组门均具有相同的结构和机构。机身右侧的乘客/机组门与左侧的门呈镜像对称。前乘客/机组门的几何外形与中、后乘客/机组门不同（中门与后门几何外形相同）。

乘客/机组门采用失效安全型塞式设计。门向外开启并与机身平行。应急逃生装置存放在安装于每扇乘客/机组门下部的容器内。

5 . Operation

Each passenger/crew door has two operation modes:

– normal operation,

– emergency operation.

Normal operation of the passenger/crew doors is possible from the inside and from the outside of the aircraft.

Emergency operation of the passenger/crew doors is only possible from the inside of the aircraft. An attempted emergency operation from the outside of the cabin causes a normal operation of the door.

5. 操作

每扇乘客/机组门有两种操作模式：

– 正常操作

– 应急操作

乘客/机组门的正常操作可从飞机内部和外部进行。

乘客/机组门的应急操作只能从飞机内部进行。从客舱外部尝试进行应急操作将导致门执行正常操作。

F. Door Damper and Emergency Operation Cylinder (Ref. Fig. 008)

A door damper and emergency operation cylinder (referred to as the damper cylinder) is attached to the support arm. Its primary components are:

– a body with hydraulic damping system

– an operating rod

– a percussion mechanism

– a shear pin

– a gas cylinder

– a pressure gage

– a charging valve.

The damper cylinder has a pressure gage, which is temperature compensated. It indicates the pressure in the gas cylinder. If the pressure is too low you can refill the cylinder through the charging valve.

The Cabin Intercommunication Data System (CIDS) (Ref. 23-73-00) also monitors the pressure in the cylinder. If there is a low pressure an indication is given on the DOORS/SLIDES page of the Flight Attendant Panel (FAP) (Ref. 52-71-00).

The damper cylinder has two functions:

(1) Normal Operation

During normal operation of the passenger door, it controls the speed at which the door moves (this is important if the wind speed is high).

(2) Emergency Operation

During emergency operation, the door damper helps to open the door (the door damper is then an actuator).

F. 门阻尼器及应急操作缸（见图008）

门阻尼器及应急操作缸（简称阻尼缸）安装在支撑臂上。其主要组成部分包括：

– 带有液压阻尼系统的缸体

– 操作杆

– 击发机构

– 剪切销

– 气瓶

– 压力表

– 充气活门

阻尼缸设有带温度补偿功能的压力表，用于指示气瓶内的压力。如果压力过低，可通过充气活门为气瓶重新充气。

客舱内部通信数据系统（CIDS）（参见 23-73-00）也会监控气瓶压力。当压力过低时，客舱乘务员面板（FAP）上的 DOORS/SLIDES 页面（参见 52-71-00）会给出指示。

阻尼缸具有两个功能：

（1）正常操作

在乘客门正常操作期间，阻尼缸控制门的运动速度（这在风速较高时非常重要）。

（2）应急操作

在应急操作期间，门阻尼器有助于开启门（此时门阻尼器充当作动器）。
