Title of the invention: Powered Airbag for aeroplane's vertical fall during an accident

Field of Invention

This invention is used in case of aeroplane accidents, that is a powered airbag is used to control the falling of a plane in the vertical direction.

The known solutions

There have been some available methods used to support planes when having problems; however, many terrible accidents still occur including pilots' faults.

Technical nature of invention

The purpose of this invention is to assist planes in case of having uncontrollable problems. When a plane loses its height and falls uncontrollably, the powered airbag will be activated which makes the falling goes vertically, the least damageable falling direction, especially into water.

To achieve the above purpose of the invention, the powered airbag consists of an airbag; a flexible soft tube connecting the airbag with the head of the plane; a container of gas-creating material for the airbag; a valve used to activate the airbag, a button for pilot to activate the powered airbag; a gravitational acceleration sensor used to automatically activate the powered airbag.

Principle of operation: In a normal condition, the airbag will be folded and installed to the head of the plane, in the bonnet. When a problem occurs, all possible methods to control the airplane fail and it starts falling uncontrollably, the pilot will activate the powered airbag, or the gravitational acceleration sensor will automatically activate the airbag. While falling, the very light powered airbag with a larger diameter than that of a plane will be able to turn the head of the plane upwards and the tail downwards due to a hindered force. At the same time, the power of the plane's engines can be used more to blow a force downwards against the gravitational acceleration by the pilot or the automatic system, this will lower considerably the damages to the plane. Preferably, a fall to the sea will bring the best result. Figure of the drawings

The benefits of the invention:

+ lower considerably the damages to a plane when an accident occurs

+ If the plane falls vertically with the head up into the water, it may stay intact.

+ It may be helpful in searching for airplane accident at sea.
