Description

[0001] Emergency door opening and damping system [0002]

The present invention relates to an emergency situation door opening and damping system, and more particularly, to an emergency situation door opening and damping system capable of providing the necessary power for an emergency situation and providing a damping force while the aircraft door is open.

Generally, the EPAS (Emergency Power Assist System) is an aircraft door operating system mounted on an aircraft door.

Generally, in the case of an aircraft door, a snubber consists of an actuator and a gas bottle, and limits the opening and closing speed of the aircraft door in normal and emergency situations.

In an emergency situation, such as a landing or an emergency landing, the aircraft body may tilt and the aircraft door may not open easily due to interference with obstructions or other debris.

What is required is a system to help the aircraft door open forcefully so that the aircraft door can be opened safely and quickly so that passengers can safely escape in an emergency.

There have been significant developments in multi-purpose compact door opening and damping mechanisms for modern commercial aircraft doors. The doors are used as an exit for emergency evacuation and everyday use by passengers, periodic service and maintenance, and passengers and crews have been developed to be able to leave the aircraft in a timely manner.

The door opens conveniently and quickly to suit the general situation or emergency situation and has no effect on the surrounding structures and people. Another approach is to use power door opening.

This generally achieves an opening rate more easily in an emergency situation, but it involves many disadvantages, such as the combination of numerous complex parts, the ability to maintain difficulty, and the lack of flexibility.

Another meaning of aircraft door assisted opening is rapid door opening. Some systems use springs in the energy storage space and provide an axial force on the pneumatic cylinder instead of a linear slide. Such a system has a problem in that the spring force is slightly reduced during the usable period, and the energy density of the mechanical spring is lowered.

And, the pneumatic linear actuators allow the drive chain system to be combined with pneumatic linear work pieces with door opening. The disadvantage of this system is that it is heavy and expensive and difficult to maintain.

The aircraft doors are applied to pneumatic cylinder shafts and are basically rotated or linear. The opening and closing of the door can be easily operated, but it is difficult to control the door movement or attenuation of the required operating speed.

In addition, since the amount of gas discharged from the safety valve is not constant, it is difficult to keep the pressure of the gas for driving the aircraft door constant. To control the pressure of the gas, structural problems and correction work must be performed.

Accordingly, there is a need for a system that provides the necessary gas pressure in an emergency and controls the damping force of the door upon opening of the door.
