Abstract
Description
そして、燃料タンクの内部の点検・保守作業等を行うため、主翼の表面に、開口部が形成されている。通常時においては、この開口部はアクセスドアにより閉塞され、点検・保守作業等を行うときには、アクセスドアを開放する。
ドア本体、クランプリングは、それぞれ開口部よりも大きな外形寸法を有している。ドア本体の外周部と、クランプリングの外周部とで、開口部の周縁部を挟み込んだ状態で、ドア本体とクランプリングとがファスナ部材等により締結されることで、ドア本体により開口部を閉塞する。
このため、従来より、主翼の内部側に配置されるドア本体の外周部と、主翼側の開口部との間に、リング状の絶縁材を挟みこむ構成が採用されている(例えば、特許文献1~3参照。)。このような構成では、絶縁材を挟み込むことによって、ドア本体の外周部と主翼側とが電気的に直接接触しないようにして、この部分から燃料タンク内にアーク、スパークが生じるのを防ぐ。
本発明は、このような技術的課題に基づいてなされたもので、耐雷機能をより確実に維持することのできる開口部の閉塞部材を提供することを目的とする。
これにより、第一スペーサが脱落したときには、第二スペーサが閉塞部材本体の外周部と対向面との間に挟み込まれるので、閉塞部材本体とパネルとの間にクリアランスを確保することができる。
このような第一スペーサ、第二スペーサは、閉塞部材本体の周方向に間隔を隔てて複数を設けるようにしても良いが、第一スペーサおよび第二スペーサの少なくとも一方は、閉塞部材本体の周方向に連続するリング状とするのが好ましい。
さらに、閉塞部材本体の外周部において、第一スペーサと対向する部分は、第一スペーサが脱落して第二スペーサが閉塞部材本体の外周部と対向面との間に挟み込まれた状態では、対向面との間にクリアランスを有しているよう形成する。これにより、閉塞部材本体とパネルとの間で落雷時にアーク、スパークが発生するのを確実に防止できる。
この場合、シール材は、押しつぶされて閉塞部材本体とパネルとの間のクリアランスが確保できなくなるのを防ぐため、芯材と、芯材よりも柔軟な材料で形成されたシール部を有するのが好ましい。
このような開口部は、航空機であればいかなる箇所、用途であっても良いが、機体を構成する主翼に設けられ、主翼内に収容された燃料タンクへの出入り口である場合に特に有効である。
図1は、本実施の形態における開口部の閉塞部材を適用した航空機の機体を構成する主翼10に設けられたアクセスドア(閉塞部材)20を、主翼10の内側から見た斜視図である。
アクセスドア20は、主翼10の内部空間に設けられた燃料タンク内に整備担当員が出入りするため、主翼10の上側または下側の表面を形成する翼面パネル(パネル)11に設けられている。
各受け部33は、主翼10の内部空間側に向けて突出しており、クランプリング40に対向する側に開口した凹部33aが形成されている。そして、凹部33a内に、ファスナ部材50を構成するナット51をリテーナ53によって保持するとともに、ファスナ部材50を構成するファスナ本体52の軸部52aを収容する。
クランプリング40には、外表面40a、対向面40bを貫通する貫通孔41が、ドア本体30の受け部33に対応した位置に形成されている。各貫通孔41には、ファスナ部材50の軸部52aが挿通される。各貫通孔41において、主翼10の外表面に対向する側に、ファスナ部材50の頭部52cを収容するテーパ状の座面42が形成されている。
また、翼面パネル11の開口部12の内周部には、クランプリング40の対向面40bの外周側に当たる当たり面14が形成されている。
そして、クランプリング40は、ガスケット43を介して、当たり面14、34に突き当たるよう取り付けられる。
突き当たり面32aにおいて、リング溝60の内周側に位置する環状の外周平面部62と翼面パネル11の翼内表面11bとの間には、環状で所定の厚さを有した第一絶縁体(第一スペーサ)63が挟み込まれている。ここで、第一絶縁体63は、例えばフェノリック樹脂からなり、外周平面部62に接着剤により接着されている。
また、突き当たり面32aにおいて、リング溝60の外周側に位置する環状の内周平面部64と翼面パネル11の翼内表面11bとの間には、環状で所定の厚さを有した第二絶縁体(第二スペーサ)65が設けられている。ここで、第二絶縁体65は、例えばガラスファイバー強化樹脂からなり、内周平面部64に接着剤により接着されている。
また、第一絶縁体63と第二絶縁体65は異なる材料で形成されているため、同一の要因で剥がれが生じるリスクを回避することができる。
また、第一絶縁体63、第二絶縁体65の材質は上記に挙げたものに限るものではない。上記以外にも、ポリイミド、PET、エチレン系樹脂等をはじめとして、絶縁性、耐熱性、耐油性、接着性等所要の条件を満たす材質であればいかなるものを用いても良い。
これ以外にも、本発明の主旨を逸脱しない限り、上記実施の形態で挙げた構成を取捨選択したり、他の構成に適宜変更することが可能である。
