Abstract

Provided is a coupling structure for airframe components that is capable of ensuring sufficient lightning protection capability. A conductive pattern part 40 made of a conductive material is formed around each fastener member 24 between wing surface panels 21A and 21B. The conductive pattern part 40 is formed, for example, around each of holes 21c and 21d on the plane on which the wing surface panel 21A and the wing surface panel 21B abut against each other. Then, the conductive pattern part 40 is pushed against both the wing surface panel 21A and the wing surface panel 21B by the fastening power of the fastener members 24, whereby electrical conduction between the wing surface panel 21A and the wing surface panel 21B can be achieved.

Claims5

Dependent claims

A coupling structure for airframe components, comprising:

a fastener member that is inserted into a through-hole to fasten a plurality of members constituting an airframe of an aircraft, the through-hole being formed in a portion in which the plurality of members are placed on top of each other;
a conductive area that is formed of a conductive material in a given part of a portion in which the plurality of members are opposed to each other;
and
an insulating area that is formed of an insulating material in a portion other than the given part, of the portion in which the plurality of members are opposed to each other, wherein
the insulating area is formed on an end part side of a member located on an inner side of the airframe among the plurality of members with respect to the conductive area in the portion in which the plurality of members are opposed to each other.
