Description

[0001] DESCRIPTION

[0002] A PROTECTION MECHANISM

[0003] The present invention relates to a protection mechanism that stops and / or damps the impact on the structural part due to the strike in case of an object hitting the structural parts in aircraft.

[0004] Bird strikes cause damage to many aircraft and cause accidents in aviation. In order to minimise the bird strike problem, the thickness of aircraft wing structural parts can be increased or high-strength materials can be preferred in the production of structural parts. Such reinforcements against bird strike cause an increase in the weight of the aircraft and cause negative effects such as flight performance and therefore fuel consumption.

[0005] In the Chinese patent document numbered CN1 10304237B in the state of the art, an aircraft wing structure that helps resist impacts such as bird strikes is mentioned. The leading edge portion of the aircraft wing comprises a leading cabin beam, at least one support rib in the leading edge cabin beam, a skin that connects to the leading edge cabin beam and encloses an interior space with the leading edge cabin beam, with the support rib located in the interior space. The leading edge portion also comprises at least one tensioning cable. By placing the tensioning cables on the leading edge of the aircraft wing, it can damp this impact force and reduce its effect when the aircraft wing receives an impact such as a bird strike.

[0006] By means of a protection mechanism developed with the present invention, elements such as birds hitting the structural parts of the aircraft are prevented from advancing into the interior after hitting the structural part, thus reducing damage to the structural part.

[0007] Another aim of this invention is to provide protection to the structures against object impact without being affected by situations such as expansion of the aircraft that occur in different weather conditions, by keeping the protection mechanism tensioned with a pre-tension. Another aim of this invention is to provide a protection mechanism with a practical and durable structure.

[0008] The protection mechanism defined in the first claim and the claims dependent on this claim, which is realised to achieve the aim of the invention, comprises at least one structural part on the aircraft. The aircraft can be a plane. There are at least two support structures that enable the structural part to maintain its form to carry the loads it is exposed to and provide strength to the structural part. There is a shell that surrounds the support structures and covers them so that they do not come into contact with the external environment, forming the aerodynamic outer surface of the aircraft in contact with the air. The shell forms part of the aircraft exterior in conjunction with the support structures. There is at least one wire extending between the support structures. While the aircraft is cruising, objects coming to the aircraft hit the wire. The wire slows down objects and absorbs the impact they create on the surface they hit.

[0009] The protection mechanism of the invention comprises at least one spring connected to at least one end of the wire. The spring stores energy while it is stationary, keeping the wire tensioned. Thus, by means of the spring, the wire is loaded with a pre-tension in every case. If an object hits the wire, the spring releases its energy and applies force to the wire, stopping the object from advancing through the wire and returning the wire to its previous position.

[0010] In one embodiment of the invention, the protection mechanism comprises a chamber containing the spring. The chamber limits the movement of the spring and stops the wire from moving further after a certain point. At the same time, it protects the spring from environmental effects by surrounding it.

[0011] In one embodiment of the invention, the protection mechanism comprises an intermediate support structure located within the structural part. The intermediate support structure helps bear the loads on the structural part. There are wires symmetrically connected to the intermediate support structure on both sides of the intermediate support structure. Symmetrical wires are connected to each other by the same spring. The spring holds the strings with pre-tension. In this way, when they meet the objects approaching them, a damping effect is created on the progress of the objects in the structural part and the object is stopped. In this way, a two-sided protection mechanism is provided for the intermediate support structure located almost completely in the middle of the structural part.

[0012] In one embodiment of the invention, the protection mechanism comprises at least two openings on the chamber. The wire is bent and passed through the chamber. The spring is passed through the hole formed by bending the wire. Thus, the spring is attached to the wire.

[0013] In one embodiment of the invention, the protection mechanism comprises at least one cover surrounding the chamber. The chamber is located inside the cover. The cover allows the wire to be mounted on the support structure.

[0014] In one embodiment of the invention, the protection mechanism comprises an outer cover that allows the cover to be mounted on the support structure. There is an opening on the outer cover. One end of the spring is passed through the opening on the outer cover, and the other end is passed through the wire. In this way, a one-sided protection mechanism is provided for the support structures located at the ends of the structural part.

[0015] In one embodiment of the invention, the protection mechanism comprises a bearing located between the chamber and the cover. The chamber and cover are preferably produced from metal materials, making them durable and sturdy. Since they are metal, there is a bearing between them to protect the chamber and cover against possible friction and / or abrasion.

[0016] In one embodiment of the invention, the protection mechanism comprises a washer that protects the chamber and the cover against friction in the part where the wire is connected to the spring.

[0017] In one embodiment of the invention, the protection mechanism comprises a structural part that is a wing. The leading edge of the wing can be a structural part.

[0018] In one embodiment of the invention, the protection mechanism comprises a support structure called a rib. The protection mechanism realised to achieve the aim of this invention is shown in the attached figures, and of these figures:
