Definitions
- the invention relates to a structural element of an aircraft with a cavity according to the preamble of claim 1.
- Aircraft have the problem that moisture condenses in the cavities of structural elements of the aircraft due to the large temperature differences on the ground and in the air, when the structural elements have thermal contact with the outer skin of the aircraft. It accumulates in some cavities especially a lot of moisture. However, moisture is undesirable for reasons of corrosion, also condensed moisture can run uncontrolled, for example in the form of water droplets.
- thermoplastic drainage funnels are riveted in a wall section of the respective cavity through which condensed moisture can flow.
- these hoppers are standard parts, they nevertheless have the disadvantage that a large drainage hole must be provided, which leads to a high mechanical load on the affected components of the aircraft.
- the assembly with up to six rivets is relatively expensive.
- aluminum drainage channels are attached.
- welded aluminum drainage channels can be used in a variety of ways, they are not standard parts and are more difficult to produce and assemble. Furthermore, they have a relatively high weight.
- Object of the present invention is to provide a structural element of an aircraft with a cavity, the production of which requires less effort on components and Montageverraumen and with which the mentioned disadvantages are avoided, which occur in the prior art. This object is achieved by the structural element according to claim 1. Preferred embodiments of the invention are the subject of the dependent claims.
- the invention is based on the idea to arrange a drainage element in the structural element with a cavity comprising a hollow cylinder with an external thread and a head at one end of the hollow cylinder, wherein the diameter of the external thread is smaller than the diameter of the head.
- the drainage element can be inserted in an opening through a wall of the structural element and screwed on the external thread on the opposite side.
- a communicating connection is made from the cavity through the wall to the outside, through which the cavity is vented.
- the structural element according to the invention of an aircraft with a cavity and an opening in a wall of the cavity through which moisture in the cavity can escape into the environment, wherein in the opening a drainage element is provided for sealing the opening in the wall of the cavity is characterized characterized in that the drainage member comprises: a hollow cylinder connecting the cavity to the environment, an external thread having a predetermined outer thread diameter and a head at an end having a predetermined head diameter, the outer diameter of the thread being smaller than the head diameter.
- the invention thus has u.a. the advantage that the drainage element contributes little to the weight of the structural element. It is inexpensive and thus brings with it the prerequisites for a standard part.
- the screw connection is a standard method of attachment.
- the diameter of the wall bore is small, which means that the wall is mechanically stressed only slightly by the drainage nozzle.
- the drainage element can be used equally for thick and thin wall thicknesses of the structural element. The installation is simple, replacement of the drainage element is possible at any time and without difficulty.
- Fig. 1 shows schematically a wall portion of an embodiment of the structural element according to the invention partially in cross section.
- Fig. 2 shows schematically an embodiment of the drainage element of the structural element according to the invention in a disassembled state in cross section.
- Fig. 3 shows schematically an embodiment of the drainage element of the structural element according to the invention in plan view.
- Fig. 4 shows schematically an embodiment of the drainage element of the structural element according to the invention in the assembled state in cross section.
- FIG. 1 schematically shows a section through a structural element 1 of an aircraft. Shown is the lower portion of the structural element 1.
- the structural element 1 is a component of the fuselage, the aircraft interior, a door or the like.
- This structural element 1 has a cavity 2 which is empty or contains other elements (not shown) and which is closed by a wall 3. In this cavity may be collected with air from the outside penetrating or due to condensation formed moisture that must be transported into the environment to prevent corrosion or mold growth.
- an opening 4 In the wall 3 of the cavity 2 to an opening 4 is provided, through which an exchange of air between the cavity 2 and the environment takes place and moisture can pass out of the cavity 2 to the outside.
- the opening 4 receives a drainage element 5 (see Fig. 2).
- the opening 4 Through the opening 4, the water collected in the cavity can drain.
- the opening 4 is funnel-shaped. In particular, it has a depression on the surface of the wall 3, so that the opening 4 in the wall 3 of the cavity 2 represents a sinkhole whose dimensions substantially correspond to the drainage element 5 used.
- the drainage member serves to seal the opening 4 against the wall 3 of the cavity so as to prevent moisture from penetrating into and corroding the internal structure of the wall 3.
- the drainage element 5 comprises a hollow cylinder 6.
- the hollow cylinder 6 connects the cavity of the structural element with the environment, so that a communicating connection between the cavity 2 and the environment arises.
- a head 8 is provided, with which the drainage element 5 is fastened on the side of the cavity 2.
- the head 8 has a predetermined head diameter "Ko" which is so large that the head 8 can not slip through the opening 4 in the wall 3 of the cavity 2.
- the hollow cylinder 6 For screwing the drainage element 5 on that side of the wall 3, which is opposite to the cavity 2, the hollow cylinder 6 has an external thread 7 with a predetermined external thread diameter "G". This external thread 7 is so long that it emerges on the opposite side of the cavity 2 of the wall 3 from the opening 4 and can be detected by a nut 10. Therefore, various embodiments of the drainage element 5 are preferably prepared for different wall thicknesses.
- the thread 7 has an outer diameter "G” which is smaller than the diameter "Ko" of the head 8. This ensures that the drainage element 5 can be easily pushed through the opening 4 and does not hit an obstacle.
- the head 8 is preferably provided with an inner profile, which is shown in Fig. 3, which is a top view of the head from above, ie in the direction of the external thread 7 represents.
- a standardized tool such as e.g. a hexagon wrench.
- the inner profile then has in particular a regular hexagonal shape with an edge length "a".
- the head has an inlet funnel 9 to direct the draining condensation in the hollow cylinder 6 having the above-mentioned inner profile.
- the head 8 is conically shaped, wherein the narrow end of the head 8 corresponds to the diameter "G" of the hollow cylinder 6 with external thread 7 and the wide end corresponds to the outer diameter "Ko" of the head. Due to the conical extension of the head, the support surface of the head 8 in the opening 4 is increased, so that the sealing effect is increased, thus preventing liquid from penetrating adjacent to the head 8 in the inner structure of the wall 3 and leads to corrosion there.
- a seal (not shown) may be provided between the opening 4 and the drainage member 5, to prevent the ingress of moisture and the like.
- the opening angle ⁇ of the conically widened head 8 is in particular about 100 °.
- the dimensions of the opening 4 in the wall 3 of the cavity 2 and the dimensions of the head 8 of the drainage element 5 in the structural element 1 according to the invention are coordinated.
- the opening 4 a sinking depth "d" in the wall 3, which ensures that the head 8 is completely flush with the surface 13 of the wall. That is, the head height "k" of the head 8 is so small that the head 8 does not project beyond the surface 13.
- the head height "k” is the distance between the head end of the hollow cylinder 6 and the free end of the head 8.
- the surface of the head 8 is thus “d” below the surface 13 of the wall 3.
- the diameter " ⁇ 1" of the opening 4 on the inside of the wall 3 is large enough so that the head can be completely received therein.
- the diameter " ⁇ 2" of the opening 4 on the outside of the wall 3 is so large that the hollow cylinder 6 of the drainage element 5 can be pushed through without difficulty, but the head 8 of the drainage element 5 does not fit through.
- the hollow cylinder 6 has at its one end opposite the head 8 a clamping connection section 11.
- the drainage element 5 in this particularly preferred embodiment is shown in the installed in the wall 3 state in Fig. 4.
- the clamp connection portion 11 serves to hold a hose 12 mounted on the portion 11, which is fixed to the portion 11 by a clamp connection (not shown).
- the clamp connection portion 11 has a predetermined third clamp connection outer diameter "Kl" which is smaller than the outside thread diameter "G" of the thread 7. This ensures that the drainage element 5 can be easily pushed through the opening 4 and does not hit an obstacle.
- the drainage element 5 is in particular made of an aluminum alloy, but of course other materials are suitable for the production, the drainage element 5 can also be manufactured as an injection molded part made of plastic. reference numeral
