To provide a jig for forming a sealant layer which enables to quickly and accurately form a sealant layer having a required film thickness. The jig includes: a sealant cupthat overlays a sealantaround a collar; a cup holderthat determines a position of the sealant cupwith respect to a fastener member; and a dummy cupthat determines a position of the cup holderwith respect to the fastener member. The cup holderis determined in position with respect to the fastener memberby being guided along the dummy cupdetermined in position with respect to the fastener member. The sealant cupis guided along a guide of the cup holderso as to overlay the sealantaround the collarafter removing the dummy cupfrom the cup holderdetermined in position with respect to the fastener member

An aircraft of the present invention includes an outer panelmade of a fiber reinforced plastic material, a support member, and a lightning protection fastener. The fastenerincludes a metal fastener bodyhaving a shaft portionand a head portion, and an insulating membermade of an insulating plastic material and mounted to the head portion. The portionhas a frustoconical-shaped fastener seat surface. The panelincludes a receiving surfaceconforming to the fastener seat surface. The memberincludes an insulating seat surfaceretracted from a plane of the fastener seat surfacesuch that, when a portionA of the receiving surfacewhich is opposed to the fastener seat surfaceis depressed, an insulating seat surfacecomes into contact with the receiving surface

Lightning protection fastener and aircraft

To provide a lightning protection fastener or the like, that can reliably seal an arc between the cap and a member such as a wing panel. An end partA of a capon an opening side, the end partA facing a member(or member), includes a planeorthogonal to an axis line of the capA and a tapered faceformed on an outer circumferential side of the plane. A sealantthat spills out of the capA upon mounting the capA is present between the tapered faceand a surfaceof the member(sealantS).

Lightning protection fastener and cap for lightning protection fastener

Provided is a coupling structure for airframe components that is capable of ensuring sufficient lightning protection capability. A conductive pattern partmade of a conductive material is formed around each fastener memberbetween wing surface panelsA andB. The conductive pattern partis formed, for example, around each of holesandon the plane on which the wing surface panelA and the wing surface panelB abut against each other. Then, the conductive pattern partis pushed against both the wing surface panelA and the wing surface panelB by the fastening power of the fastener members, whereby electrical conduction between the wing surface panelA and the wing surface panelB can be achieved.

Coupling structure for airframe components

A barrier-film forming apparatus that forms a barrier film on an inner face of a container having a concave or convex portion as a processing target, including: a dielectric member having a cavity sized to enclose the container, an external electrode covering an outer circumference of the dielectric member, an exhaust unit installed on an end face of the external electrode on a side where a mouth of the container is located, with an insulating member interposed therebetween, and depressurizing inside of the container through an exhaust pipe, an internal electrode inserted from a side of the exhaust pipe and also serving as a gas blowout unit that blows out medium gas for generating a barrier film into the container, and an electric-field applying unit that applies an electric field for generating exhaust between the external electrode and a ground electrode.

Barrier-film forming apparatus, barrier-film forming method, and barrier-film coated container

A sealantfilled into a capA is caused to overflow through both an opening in a first end portionof the capA and a through-holeof the capA when the capA is pressed against a fastener member. With regard to the capA, a ratio between inside diameter Dof the opening on the side of the first end portionand hole diameter Dof the through-holein the second end portionis set as follows: 0.10&#x2266;D/D&#x2266;0.27.

Lightning protection fastener and mounting method thereof

In an insulating coverA according to the present invention, a dimension of each of an outer-circumferential-side cylindrical partand an inner-circumferential-side cylindrical partfitting in step partsandin an axial direction of a fastener bodyis set large with respect to a tip covering partcovering a tip surfaceof a fastening member. As a result, on an outer circumferential side and an inner circumferential side of the fastening member, a distance from a memberis sufficiently ensured by the cylindrical partand. The tip covering partis thinner than the cylindrical partB and. Therefore, when the fastener bodyand the fastening memberare fastened together, the amount of deformation of the tip covering partin a thickness direction can be made small.

Lightning-protective explosion-preventive fastener

A lightning-protection fastener is provided that is capable of reliably preventing peeling off of an insulation layer during the operation of an aircraft and improving the anti-lightning-strike capability and reliability. There is a lightning-protection fastener that fastens a skin of an aircraft and a structural member positioned inside the skin, in which an insulation layer is melt adhered so as to cover one end surface of a head portion and also to mechanically engage with a fastener-side engagement portion (engagement portion) formed on the end surface.

Lightning-protection fastener

A long-life lightning protection fastener or the like to prevent explosion for aircrafts at low cost is provided, the fastener having a light weight, ensuring sufficient lightning protection, and having extremely less failures and high reliability. A ring-shaped ring memberA made of resin is mounted on a collar. This ring memberA is interposed between a memberand the collarand is in intimate contact with both of the memberand the collar, thereby sealing an interface with the memberfor sealing and preventing the occurrence of an arc at an outer perimeter edge of the collar
