PROBLEM TO BE SOLVED: To provide a method for giving robust property to leak detection, a piping structure capable of materializing the method and an aircraft with the piping structure.SOLUTION: A piping structure 10 comprises: a pipe 20 that includes a plurality of ducts 21 where gas having temperature higher than temperature in a surrounding atmosphere flows continuously and includes a plurality of couplings 22 for connecting the ducts 21 with each other and that is arranged along an approximately-horizontal direction; and a cover 23 that covers an outer periphery of the pipe 20. The cover 23 defines a plurality of air holes 31 and 32 which allow gas leaked from the pipe 20 to discharge to the outside of the cover 23, at intervals in a length direction of the pipe 20. Each position of at least first air holes 31 respectively corresponding to a plurality of locations 201 where the ducts 21 are connected to each other, out of the air holes 31 and 32, is substantially defined within a range from a two-o'clock position to a ten-o'clock position through a six-o'clock position in a cross-section of the cover 23.SELECTED DRAWING: Figure 2

    【課題】リーク検知にロバスト性を与える方法、当該方法を実現可能な配管構造、およびその配管構造を備えた航空機を提供すること。【解決手段】配管構造10は、周囲の雰囲気の温度よりも高い温度の気体が連続して流れる複数のダクト21およびダクト21同士を接続する複数のカップリング22を有し、略水平方向に沿って配置される配管20と、配管20の外周を覆うカバー23と、を備えている。カバー23は、配管20からリークした気体を当該カバー23の外側へと流出させる複数の通気孔31,32を配管20の長さ方向に間隔をおいて規定している。複数の通気孔31,32のうち、少なくとも、ダクト21同士が接続される複数の箇所201にそれぞれ対応する第1通気孔31の各々の位置は、カバー23の横断面において2時位置から6時位置を経て10時位置までの範囲に、実質的に定められている。【選択図】図2
