Emergency evacuation system, in particular for a tailless aeroplane

Abstract

A system for selective emergency evacuation of persons from a first level (I) to a second level (II) located above the first level (I) or to a third level (III) located under the first level comprisesfor evacuation to the upper level a stairs-shaped arrangement (1). According to the invention, the system is connected at one end with the first level (I) and at the other end it can be displaced between the upper level (II) and the lower level (III) or vice-versa, and can be altered to take the form of a slide (2) for evacuation to the lower level (III).; In particular, the system can be advantageously used for selective emergency evacuation of persons from a deck which forms the first level (I), in particular a passenger deck (17) of a tailless aeroplane (20), to the upper side (18) of thetailless aeroplane (20), which forms the second, upper level (II), or to the underside (19) of the tailless aeroplane (20), which forms the third, lower level (III).

Description

[0001] This application claims priority from German Patent Application No. 10 2005 044535.7 filed September 17, 2005, the content of which is hereby incorporated by reference. technical field [0002] The present invention relates to a device for selectively evacuating people from a first floor to a second floor above the first floor or to a third floor below the first floor as required. Background technique [0003] The prior art relates to commercial aircraft comprising a more or less cylindrical pressure chamber which is isolated from the surrounding environment by a passenger door. For evacuation purposes, provision must be made to ensure that passengers can pass through an open door on one side of the aircraft via an evacuation slide to the outside from the aircraft within 90 seconds. [0004] In the event of an emergency landing on water, due to the volume provided below the cabin, ideally the aircraft remains suspended for a predetermined time such that the lower edge...

AI Technical Summary

Problems solved by technology

[0006] With regard to emergency evacuation, there is a significant difference between conventional commercial aircraft and non-traditional wing-body aircraft, which are also called tailless aircraft, because, according to the current design, in the wing-body aircraft Most emergency evacuation doors or hatches do not provide direct access from the passenger cabin to the outside world, because for structural reasons it is not possible to rationally design the entire wing volume as a pressurized compartment
