Abstract

Abstract Todays applied design principle of vehicle doors in e.g. aircraft leads to the problem that the cover plate, which is applied to the upper door surrounding, has the problem that it is damaged by fatigue caused by flutter of the cover plate. Different technologies are presented which shall prevent the cover plate flutter phenomena and therefore lead to a mature reliable solution which saves cost and maintenance effort.

Cover plate locking mechanisms

Todays applied Design principle of vehicle doors in e.g. aircraft leads to the problem that the cover plate, which is applied to the upper door surrounding, has the problem that it is damaged by fatigue caused by flutter of the cover plate.

Picture 2 – as is solution with cover plate

Picture 3 – as is solution with cover plate – detailed view with intersection

In the following different technologies are presented which shall prevent the cover plate flutter phenomena and therefore lead to a mature reliable solution which saves cost and maintenance effort.

Picture 4 – The flutter of the cover plate is prevented by the generation of a negative differential / by applying a vacuum pressure due to spoilers / suction diffusers driven by the airstream and sealing and by that the cover plate is pressed to the skin of the airframe

Picture 5 – The flutter of the cover plate is prevented by the use of spoilers which are disturbing the airstream around the cover plate environment and by that leading to pressure conditions which prevent the flutter phenomena. The cover plate is pressed to the skin of the airframe.
