Abstract

The present disclosure relates to a structural component of an aircraft wing body and an aircraft including the structural component. According to an aspect of the present disclosure, a structural component of an aircraft wing body is provided. The structural component includes a body part and a profile. The body part includes an edge portion formed by end portions of a first skin and a second skin of the body part superposed together. The profile is attached to the edge portion. The profile has an outer profile conforming to an outer profile of the body part such that the structural component, as a whole, exhibits an aerodynamic outer profile after the profile is attached to the edge portion. The profile is attached to the edge portion via a plurality of separate intermediate members or by contacting the edge portion.

First claim

The invention claimed is:

1. A structural component for an aircraft wing body, comprising:
a body part having an outer profile;
a profile member having an outer profile;
wherein the body part comprises an edge portion formed by end portions of a first skin and a second skin of the body part superposed together, the profile member being attached to the edge portion;
wherein the outer profile of the profile member conforms to the outer profile of the body part such that the structural component, as a whole, exhibits an aerodynamic outer profile after the profile member is attached to the edge portion;
wherein the profile member is attached to the edge portion via a plurality of separate intermediate members, or wherein the profile member is attached to the edge portion by contacting the edge portion;
wherein the profile member is a substantially U-shaped profile having a first branch portion and a second branch portion, and the profile member is attached to the edge portion in such a manner that the edge portion is disposed between the first branch portion and the second branch portion;
the profile member is made of a composite material and is provided with a profile-conductive-region on the outer profile;
a sealant disposed between a portion of the first branch portion and the first skin,
the at least one of the plurality of separate intermediate members comprises a conductive fourth intermediate member which is in contact with a body-part-conductive-region and is electrically connected with the profile-conductive-region,
the edge portion comprises a first side surface facing the first branch portion and a second side surface facing the second branch portion, and only the first side surface is provided with the body-part-conductive-region,
the fourth intermediate member contacts the first side surface, and
a fifth intermediate member is provided in a first space between the fourth intermediate member and the first branch portion, and a sixth intermediate member is provided in a second space between the second side surface and the second branch portion.

2. The structural component according to claim 1 , wherein the body-part-conductive-region extends to the edge portion.

3. The structural component according to claim 1 , wherein the body-part-conductive-region comprises a copper mesh, the profile-conductive-region comprises a copper mesh, the fourth intermediate member is made of a copper plate, the fifth intermediate member is a sealant, and the sixth intermediate member is made of glass fiber reinforced plastic.

4. The structural component according to claim 1 , wherein:
the profile-conductive-region is provided on an outer surface of the profile member, and
the profile-conductive-region is electrically connected with the fourth intermediate member via a washer in contact with the profile-conductive-region and a conductive fastener in contact with the washer.

5. The structural component according to claim 1 , wherein the profile member is provided with at least one cutout portion allowing a portion of the fourth intermediate member to be exposed.

6. The structural component according to claim 1 , wherein a vertex space defined by a vertex section of the profile member is vacant without any members being disposed therein.

7. The structural component according to claim 1 , wherein a countersunk fastener adapted to fasten the profile member to the body part is provided.

8. The structural component according to claim 1 , wherein the aircraft wing body comprises an empennage and a wing, and the structural component is an elevator of a horizontal empennage of the empennage, a horizontal fin plane of the horizontal empennage of the empennage, a rudder of a vertical empennage of the empennage, a vertical fin plane of the vertical empennage of the empennage, a winglet of the wing and/or an aileron of the wing.

9. An aircraft comprising the structural component according to claim 1 .
